Sony a7C2 (ILCE-A7CM2) Review

Dustin Abbott

November 10th, 2023

About three years ago Sony debuted their first Sony a7C model, a compact full frame camera with a body similar to their APS-C models like the a6600 but with the internals of the Sony a7III…howbeit improved in a number of areas. They shrunk the IBIS (In-Body-Image-Stabilization) system, improved the autofocus, and the end result was an effective little camera that is great if you’re wanting to travel light. As always, there were some ergonomic compromises made at the altar of compactness (a less than stellar viewfinder, fewer physical controls), but the camera was a great pairing with the many compact lenses available in E-mount, from Sony’s mini-lineup of F2.5 G lenses to Samyang’s “Tiny” series and even many of Sigma’s I-series lenses. I’ll provide a quick link directory to some of the great lens options for this compact camera down below. The success of the a7C paved the way for its successor to arrive in 2023, and today’s review breaks down the performance of the new Sony a7C2, which Sony dubs the ILCE-A7CM2. The a7C2 has slightly improved ergonomics and is largely built around the internals of the a7IV, a camera which my team owns and really likes. Sony has also released an a7CR which does something similar with the 61MP sensor from the Sony a7RV. You can find out all of my thoughts in the video review below…or just keep reading.

Thanks to Sony USA for sending me a review loaner of this camera. As always, this is a completely independent review.

Here’s a list of great compact lens options for the a7C2 that are hyperlinked to my review of them.

In a bit of fortuitous timing, another interesting compact lens option arrived for review on the same day as the a7C2, and that’s the Viltrox AF 20mm F2.8, a very interesting (and very inexpensive) wide angle prime. Many of the photos shown in this review have been taken with that lens, as it was a very natural pairing due to the compact size.

Here is a breakdown of some of the key features of the a7C2:

  • 33MP Full-Frame Exmor R BSI Sensor
  • BIONZ XR Image Processor
  • Shooting Up to 10 fps, ISO 50-204800
  • 10-Bit Full-Frame 4K30p Video
  • S-Log3, S-Gamut3, S-Cinetone, User LUTs
  • 7 Stops of In-Body Image Stabilization
  • 759-Point Phase Detection, 94% Coverage
  • 2.36m-Dot OLED Electronic Viewfinder
  • 3″ 1.03m-Dot Vari-Angle LCD Touchscreen
  • Internal Mic + Inputs, USB Streaming

The MSRP on the a7C2 is $2198, or a savings of about $300 off the price of the bestselling a7IV. You can get the original a7C for about $1600 due to market pressures bringing the price down. The original a7C came to market at a very aggressive price point of $1800, so Sony is pushing the price up $400 in this newest iteration. We’ll see how the market reacts…

Sony a7C2 Build, Handling, and Features

The basic shape and size of the new a7C2 is near identical to the original a7C. The new a7C2 is 4.9 (W) x 2.8 (H) x 2.5″ (D) or 124 x 71.1 x 63.4 mm, while the older a7C was 4.9 x 2.8 x 2.4″ / 124 x 71.1 x 59.7 mm. Bottom line is that the cameras are the exact same size save the new a7C2 has a slightly deeper grip, which is a welcome change in my book, particularly since it comes at the cost of only 5 grams of additional weight. The a7C2 weighs 514g (1.1lb) vs the 509g of the original a7C. The feel of the grip is pretty good, though those with larger hands like myself will find the camera not tall enough; I have no place to put my pinky finger and the lower pad of my palm. It all ends up having to curl under the camera when gripping it.

The two cameras look largely the same until you look a little closer, where a few key ergonomics improvements make a big difference. Take a careful look at the two cameras from a few angles (comparison chart courtesy of mirrorlesscomparison.com):

Starting with the front view we see a key addition: there is a control wheel below the shutter button. That missing wheel was my top complaint in my review summary of the a7C. Good camera control requires at least three wheels, and I really missed that typical control touchpoint from the a7C. The addition of that wheel on the a7C2 makes using it more functional.

You might also notice that while Sony experimented with a different type of grip pattern with the a7C, they’ve returned the familiar “leather” texture style shared with most of their camera models. I noted in my review of the a7C that the new texture looked cool but didn’t provide as much grip as the older style. Sony must have agreed, as they have scrapped the new and gone back to the old.

Switching to the rear view everything looks mostly the same but with the addition of a C1 (custom) button next to the menu button. Sony moved the cut-out area that allows you to grip the screen to swing it out to the bottom and utilized that area at the top of the camera to center the MENU button more and add the C1 button that was missing on the first a7C (which takes care of another complaint of mine). The “trash” button has a secondary label of C2, giving these buttons a more familiar layout to Sony shooters from other cameras.

A look at the top shows a few important improvements. They have repositioned the ON/OFF dial so that it doesn’t interfere with the new front control dial, and also enlarged the shutter button, which is a good improvement as it will be easier to use while wearing gloves now. Sony also added a secondary dial underneath the mode dial that allows to switch between separate setups for Stills | Video | S&Q (slow and quick). This allows you to have multiple control setups (and even custom menus) for your photography and video setups, enabling this to be a better hybrid camera. Like the a7C, the “hotshoe” is Sony’s newer “Multi-Function” shoe compatible with digital audio, and Sony (along with a few other brands) have continued to release new microphones that leverage that capability.

A more subtle change is that they have removed the markings from what is (by default) the control wheel for exposure compensation. This allows more flexibility in assigning a different area of control to that wheel if so desired.

Most of the other controls are the same in location and default function. We still don’t have a navigational joystick, which I do miss.

The LCD monitor is a vari-angle (articulating) 3.0″ screen as before, but the resolution has been slightly improved to 1.04M dots of resolution (from 921,600 dots before). Sony’s touch has also improved over the past few years, and one now has full control of all menus via touch.

On the left side of the camera the ports and card slot is essentially the same though with a very slight reorganization. The top one opens up to reveal that the USB-C port has moved up to join the microphone input. You can charge the camera’s battery in camera via the USB-C port so long as your power source has the correct power delivery spec.  The middle compartment opens to reveal (thankfully!) the memory card slot.  I despise when the memory cards are relegated to the bottom of the camera with the battery; this is much easier to access. There is a single UHS-II rated SD card slot located there.

The bottom compartment opens to the side and reveals a headphone monitoring jack and a micro-HDMI port. I recognize that the size of this camera makes having a full size HDMI port difficult, but micro-HDMI always feels a little flimsy for serious video making.   

The viewfinder is still located to the left rather than central to the camera, and I continue to find that a frustrating position ergonomically. The viewfinder is mostly similar (0.39-inch OLED panel with 2.36 million dots and a maximum refresh rate of 120Hz), but it is slightly improved with better magnification (0.70x vs. 0.59x) and a longer eyepoint (22mm vs. 20mm). That’s not enough of an improvement to me, however, as the viewfinder remains a weak link in the design and I don’t particularly enjoy using it.

The a7C2 continues to utilize the same NP-FZ100 battery as before, but the newer camera is a little more power hungry, so the battery life drops from a CIPA rated 540 frames when using the monitor or around 510 images when composing with the EVF – about 200 shots poorer than the a7C. The real world battery life still feels pretty good (about the same as the a7IV), but that’s obviously a drop compared to the original a7C.

You can get the a7C2 in either the silver finish pictured in the comparison earlier or the more typical black that I’m reviewing here. The function of both cameras is the same; the different look is purely cosmetic. Either version is well made with an aluminum alloy chassis along with a wide variety of seal point to ensure the camera is ready for all weather conditions.

One core improvement is to the miniaturized IBIS system. The IBIS in the a7C was rated at 5 stops of assistance, but the new and improved version in the a7C2 is rated at a whopping 7 stops of assistance. In video mode you also have the option of selecting “Active” stabilization which throws a little digital/gyro assistance in there while moving to give more stabilization, though at a very minor 1.1x crop.

While I personally prefer a camera with a little more meat on its bones, I think that Sony has done a great job of improving the ergonomics and usability of the a7C2 while staying true to the mandate of keeping the camera small and light. The additional control points allow me to more easily imitate the setup of my normal Sony cameras, and the changes that Sony has made are subtle but add up to a significantly improved camera. I think that just about everyone can appreciate the changes Sony has made here.

Sony a7C2 Autofocus Performance

The a7C had a hybrid AF system with 693 phase and 425 contrast-detect autofocus (AF) points that covered approximately 93% of the sensor.  Sony has improved the core focus system to where there are now 759 points with 94% coverage. The low light sensitivity is -4Ev with a f/2 aperture at ISO 100.

Perhaps more important is the improved processor (BIONZ XR) and the AI processing unit that allows for more trackable subjects and more intense tracking of some existing subjects. Trackable subjects now include humans, animals, birds, insects, car/trains and airplanes.

I was impressed with the performance of the a7C at the time of my review, but there’s no question that autofocus has gotten more sophisticated since that point. The AI tracking applies to video recording as well as photos, though I will note the number of active AF points drops to 627 PD points during video recording (still plenty!)

When shooting stills, it was pretty easy to grab photos during rapid action even with the third party Tamron 70-180mm F2.8 VC G2 that I recently reviewed.

Tracking Nala can be a chore, as she is small and moves very quickly. I had fairly good success with tracking her in so-so light. The Tamron/A7C2 combo did drop some frames, but I have confidence that if I used a GM lens instead that I would have seen near perfect results.

I had my wife shoot a few frames with the 35mm F1.4 GM to highlight me using the Canon RF 28mm F2.8 STM for that review, and there was accurate focus using the 35GM even at F1.4.

There is a consequence for increasing the resolution from 24MP to 33MP but not improving the storage medium. Sony is running up against some of the limits of the data pipeline of this current configuration. You can shoot up to 10FPS (as with the a7C), so the hit isn’t to the framerate. The hit comes with the buffer depth. While the a7C could take 115 RAW or 223 JPEG images before the buffer filled, the limits (at least for some file formats) comes quicker. Here are the specs from Sony:

JPEG Extra fine L: 88 frames, JPEG Fine L: over 1,000 frames, JPEG Standard L: over 1000 frames, RAW: 44 frames, RAW and JPG: 35 frames, RAW (Lossless Compressed): 27 frames, RAW (Lossless Compressed) and JPEG: 20 frames, RAW (Uncompressed): 18 frames, RAW (Uncompressed) and JPEG: 16 frames

The maximum RAW files that you are going to see is just 44, and if you are shooting lossless compressed (my preferred format) that is dropping to 27 frames before the buffer filled. I quickly ran into that when shooting action sequences, so I had to drop to just shooting JPEGs to avoid that issue. While you’ll only see 88 Extra Fine JPEGs, you can drop to Fine JPEGs and get virtually unlimited frames. The a7IV allows you to use CFExpress Type A cards and has much, much deeper buffers (1000+ Compressed RAWs or JPEGs). If you are looking for a sports oriented camera there are better options than the a7C2.

Video AF was solid. Sony has really worked to tweak both the focus system and the AI machine learning to allow for essentially equal autofocus performance for either stills or video. This is a true hybrid camera, and I wouldn’t be surprised if a decent part of the market for the a7C2 is from those looking for a lightweight video camera that retains a quality full frame sensor. Sony has so many great lenses at this point for the system, and that includes a lot of lenses that are both compact and well equipped for video capture.

All in all, I had a mostly frustration-free autofocus experience with the Sony a7C2. The shot above was taken in very low light, but autofocus was nearly instant.  I and my team own the a7IV, a7RV, and the Alpha 1, and autofocus with the a7C2 felt pretty similar in most situations. I would say the only exception was when shooting action, but that is mostly because the Alpha 1 is such an amazing camera for sports. The a7C2 is more of a jack-of-all-trades, but it does enough of everything well enough that I think most photographers and videographers will be very happy with it.

Video Specs and Performance

The a7C was a popular camera for video enthusiasts, and that will be even more the case with the a7C2. There are some clear improvements, including the ability to shoot 4K60 (though in Super35 mode, or with a 1.5x crop). There are plenty of APS-C lenses that will allow you to retain a wide angle of view even with that crop, however. While the a7C had a minor 1.2x crop if you shot 4K30, the a7C2 uses the equivalent of a 7K area with full pixel readout and no pixel binning (no crop). While the a7C was limited to 8 bit internal recording and a maximum of 100Mbs, the a7C2 allows for 10-bit 4:2:2 internal recording and an All-Intra compression option up to 600Mbps. In other words, we’ve got much more upscale video specs with many more options. Here’s a look at the full list of video modes available:

Sony’s menus make it pretty easy to find what movie format you want and quickly employ it, and remember that you have the ability to set up custom buttons and menu options separately for video recording.

Here’s the list of video highlights courtesy of Sony.

  • Record in 10-bit 4:2:2 using the advanced XAVC S-I format for consistent performance and quality at bitrates up to 600 Mb/s.
  • Full-frame 4K recording is possible with frame rates up to 30p, up to 60p in 4K with a Super35 crop, and full HD recording up to 120p, using full 1:1 pixel readout without binning.
  • The high-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate set to either 30p or 24p.
  • Slow & Quick (S&Q) mode allows shooters to capture 4K video at specified steps between 1-60 fps and Full HD between 1-120 fps, depending on the format. These settings will allow you to slow down action as well as speed up a slow-moving scene.
  • The S-Log3 and S-Gamut3.Cine gamma curves allow for more than 15 stops of dynamic range and for increased post-production flexibility, including matching video from other Sony Cinema Line cameras.
  • S-Cinetone can be used to deliver distinct colors and healthy-looking skin tone rendering that is based on technology from the professional Cinema Line cameras, such as the VENICE. This color profile offers natural mid-tones, soft colors, and especially well-controlled highlights.
  • Creative Looks can be baked into the recorded footage to create a specific mood during recording and minimize the need for editing.
  • User-created LUTs and presets can be set for accurately monitoring footage or previewing a specific look during shooting and can be applied to the camera’s monitor, EVF, or HDMI output.

I did a variety of different filming options on the a7C2, from run and gun footage using a baked-in picture profile to Log recording. I enjoyed the ability to easily set a LUT (Look Up Table) so that you can visually see how a shot will look after some editing. Being able to add your own LUT or preset is extremely useful as well, particularly if you are filming with a certain “look” in mind. I was testing a unique Sirui anamorphic lens (1.6x), and so I got some really interesting footage with the combo (the Sirui lens is extremely lightweight, making for a very lightweight combo). Here’s a screenshot from one of those clips:

Sony’s sensors have excellent dynamic range, so if you shoot in S-Log3 you can get 15+ stops of editing room – extremely useful!

The improvements to video tracking and AI learning are very welcome for video work, and the improved Steady Shot (IBIS) is as well. This is a lot of video camera for under $2000!

If you are more video focused, I really recommend the Samyang V-AF series as they really designed with hybrid video/stills capture in mind. You can see that there are a couple of these that I haven’t reviewed as they are either unreleased or I haven’t gotten a review copy yet.

These lenses are a real treat to use on the a7C2, as they have a lot of great video-specific features and weigh in at just 280g. The compact size is a great pairing for the compact camera.

Sony a7C Sensor Performance

Where the a7C inherited the basic 24Mpx Full-Frame backlit BSI sensor from the a7III, the new a7C2 gets the upgraded 33MP full-frame Exmor R CMOS sensor from the a7IV along with the newer/faster BIONZ XR processor. The native resolution is 7008 x 4672 pixels, though recent Sony cameras (finally!) have the ability to choose lower resolution points for Lossless Compressed RAWs as well as JPEGs. You can choose L (large), M (medium), or S (small) Lossless RAW options:

  • 33 MP (7008 x 4672)
  • 14 MP (4608 x 3072)
  • 8.2 MP (3504 x 2336)

This feature is more valuable on the high resolution cameras, obviously, but there might be applications when you want/need less resolution. I’ve personally found the native resolution in the a7IV (the same sensor) to be near perfect for a lot of applications. I own the highest resolution cameras from each brand I test so that I can give lenses the most rigorous testing, but for actual photography there are few photographers that need more than 33MP. The a7C2 also supports 10-bit HEIF format recording.

The sensor in the a7C2 has slightly more dynamic range than that in the a7C, though the tradeoff is slightly more noise at higher ISO values due to the higher resolution. We’ll take a deeper look at the performance in our tests.

Dynamic Range

Dynamic range has become one those topics debated ad nauseum on photography forums and harped on by certain reviewers to the place where some perspective has been lost on the topic.  I can definitely say that there are a number of situations where improved dynamic range gives the photographer (and particularly the post-processor) more latitude to fulfill their vision. This could be in the ability to recover a blown-out sky or shadowed area as a landscape photographer or the ability to balance a foreground subject with a background or sky for portrait photographers.  I frequently use good dynamic range in portrait photography to bring up exposure on the faces of subjects when shooting with only available light. I did that with this shot taken with the a7C2/35GM because my face is naturally dark, and using dynamic range to open up the shadows some on my face definitely improves the end result.

I can also balance the exposure in a landscape image, recovering some of the sky while also bringing up some of the information in the shadows, leaving a nice looking exposure afterwards.

The a7C2 is rated at right over 15 stops of dynamic range, and while there is a lot of latitude there for recovering shadows and highlights, I did notice the capacity for some noise in the shadows with very aggressive recovery. This shot, for example:

You can see that I was able to significantly recover information previously crushed in the shadows, but at the cost of significant noise. Why? Because I was shooting at ISO 1600 rather than my tests which are done at base ISO. Remember that dynamic range is significantly attached to ISO, so if you want a lot of dynamic range, you need to keep your ISO down.

There are some good denoise tools out there now, however, including a AI Denoise tool built right into Lightroom. The tool isn’t fast (it took about 13 minutes to render this image, but the end result is significantly cleaner other than some “hot” pixels here and there.

That’s a pretty extreme recovery, however. We’ll see how the a7C2 does with my typical series of tests to be a little more scientific.

We’ll start with shadow recovery. I established a proper exposure as the base exposure, and then purposefully underexposed progressively by 1 stop through to 5 stops. In post I add the exposure back to test how well the camera does with shadow recovery. We’ll use the 4 stop example first, and you can see how deeply crushed the shadows were in the original on the left and how well they have been recovered on the right.

Zooming in to a pixel level shows just how clean that recovery is:

But even if I go all the way to 5 stops and examine the areas that should remain dark, I can see that the results are still very clean.

At base ISO there are very, very few full frame sensors that are outperforming the shadow recovery we see here. This is one of the very best performances out there.

Typically modern cameras are much better at shadow recovery than they are at highlight recovery, but Sony sensors tend to be some of the best in this regard.

In this instance I purposefully overexposed by one, two, three, and four stops and then reduced that exposure in post to test highlight recovery. I typically see most cameras do reasonably well with recovering 2 stops of highlights, but a 3 stop recovery is rare, and a 4 stop recovery just doesn’t happen.  Several things happen in overexposed images: there are “hotspots” where textures and details are blown out and various colors start disappearing. If you look at the image on the left below, you can see that both of these things are true. But the recovered image on the right looks fairly good. There are a few hotspots where a bit of information is lost, but most of the colors are back and the image looks natural.

That’s actually one of the best 3 stop highlight recoveries I have seen. If we zoom in we can see that most of the textures and colors have been recovered, with only a few exceptions.

If we try to push our luck and go for 4 stops, we quickly find the limit.

I’ve never seen any camera pull off a 4 stop overexposure successfully, and the a7C2 isn’t the first. Still, however, this is up there among the best of Sony’s sensors, and Sony’s sensors are some of the very best on the market for dynamic range performance.

ISO Performance

The Sony a7C2 has a 100-51200 native range with extended levels that go as low as 50 and as high as 204800.  I typically don’t recommend going into the extended levels (particularly on the high end), as you get reduced performance.

If you look on a global level, there is very little visual difference between ISO 100 and ISO 12,800.

If we zoom into a pixel level we can see that there is some additional noise and that the shadows are raised a bit due to some uneven pixels.

A look a the textures elsewhere show that fine noise pattern, but nothing too disturbing.

Moving up to ISO 25,600 shows the pattern continuing. There are more uneven pixels in the shadow information and the noise gets a little rougher. By ISO 51,200 you can see the effects even at a global level.

If you move up into the expanded limit, you’ll start to see some other issues like a green color shift and more patterns in the shadowed areas. I would avoid the expanded zone above 51,200. Even at lower ISO settings (ISO 12,800, in this case) I can see some odd effects in certain images in the out of focus area, like here:

There is some patterning in what should be a uniform area to the right of the guitar. I think it is more obvious in a monochrome, but I can see it some in the area above the books in this ISO 25,600 image.

That is shooting in very low lighting conditions (nearly dark), however, and you will get better results in better lighting conditions. I regularly set my ISO at 3200 or 6400 in church or event settings to eliminate motion blur and hardly notice the noise.  Here’s one at ISO 3200 from this last Sunday:

The Sony a7C2 isn’t quite as good as the a7C for low light performance due to the higher resolution point, but it remains a good option in most ISO conditions.

Color

Sony has slowly and steadily tweaked its color science over the past five years. The end result is a more nuanced performance that is very close to the level of Canon and Fuji, though I do very slightly prefer those brands for their color. One thing I will say is that Sony’s cameras do a better job with white balance than what either of those other brands do. When doing my chart tests, for example, I always have to correct the white balance when testing on either Canon or Fuji, but my Sony test cameras deliver a consistently good white balance with a variety of lenses. Sony has always done a good job with colors for landscapes:

What has improved over time is their skin tones, which are now more natural with a variety of different skin types. Here’s an uncorrected image that shows a few different skin tones, all of which are rendered accurately.

Sony has updated their “creative looks” with some new options. This is their version of Fuji’s film simulations, and while Sony’s options aren’t as varied or interesting as Fuji’s, there are some widely different ways to approach your images. Here’s a shot taken with the Viltrox AF 20mm F2.8 and rendering with Adobe’s Standard color profile:

What will follow is a series of the same image using Sony’s color profiles along with Sony’s descriptions of what each creative look does. Here’s that same image using  ST:Standard finish for a wide range of subjects and scenes.

 PT:For capturing skin in a soft tone, ideally suited for shooting portraits.

 NT:The saturation and sharpness are lowered for shooting images in subdued tones. This is also suitable for capturing image material to be modified with a computer.

VV:The saturation and contrast are heightened for shooting striking images of colorful scenes and subjects such as flowers, spring greenery, blue sky, or ocean views.

 VV2:Creates an image with bright and vivid colors with rich clarity.

 FL:Creates an image with moody finish by applying sharp contrast to the calm coloring as well as the impressive sky and colors of the greens.

 IN:Creates an image with matte textures by suppressing the contrast and saturation.

 SH:Creates an image with bright, transparent, soft, and vivid mood.

 BW:For shooting images in black and white monotone.

One final option not shown is  SE:For shooting images in sepia monotone.

There are plenty of options to play with there. Obviously different looks are going to suit different scenes/subjects better than others, so developing some familiarity with them might be useful. Remember that you can also select any of these creative looks for video as well. You can check out many more images from the camera by visiting the image gallery here.

Sony FE 28-60mm F4-5.6 Kit Lens

Sony debuted a new kit lens with the a7C, a retractable zoom design.  That lens continues to be the standard kit lens with the a7C2, and, while I didn’t have a copy of the lens with my loaner of a7C2, I did previously review the lens with the original a7C. I’ll include that section here for those interested.

I personally have a hard time getting excited over any lens with a small, variable aperture and that only reaches 60mm, but I have to confess that I was very pleasantly surprised with the optical performance of the Sony FE 28-60mm F4-5.6 kit lens.

First of all, however, let’s take a quick look at the build.  When in the retracted position, the FE 28-60mm is a miniscule 45mm in length, which is considerably shorter than the 83mm for the 28-70mm.  It also weighs in at only 5.9 oz / 167g, which is considerably less than the 10.41 oz / 295g of the 28-70mm.  This is obviously going to really enhance the idea of portability in the lens.

The lens is 66.5mm in diameter, but because of the retracting inner barrel, the filter size is a very odd 40.5mm.  Frankly I have never seen any lenses with this filter size before, so I was surprised to discover that a number of filters do exist in this unusual size.  They are pretty universally inexpensive, as well.

Sony has elected to not include OSS in the new lens, likely due to the fact that most of their recent cameras have IBIS whereas almost none did when the 28-70mm was released.  Since I tested in on the a7C, which does have effective IBIS, I didn’t notice the lack of OSS in the lens at all.  IBIS did an effective job for my purposes.  The first shot I shared in this section was taken at 1/20th of a second and is tack sharp.

The retractable design requires you to first extend the inner barrel to the 28mm position before use.  This extension adds around 30mm to the overall length.  

The action to move it from the retracted position to the 28mm is quite stiff, with a fair amount of force required to start the process and again right before the 28mm (engaged) position.  I can understand the need for resistance at these points, but the action here feels a little cheap and betrays the lack of engineering sophistication in the lens.

The rest of the design is pretty straightforward, as there aren’t a lot of bells and whistles here.  The length of the lens changes depending on focal length, and it is a “dip” design where it is longest at 28mm and 60mm with a “dip” to a slightly shorter length around 38mm.  There’s a very slight variance in resistance as you turn the zoom ring near that point, and the zoom ring action itself is not particularly smooth.  Not a big deal, but again it is one of the reminders of the “kit lens” origins.

The maximum aperture varies by focal length.

  • F4 – 28-30mm
  • F4.5 – 31-34mm
  • F5  – 32-41mm
  • F5.6 – 42-60mm

This is not a “fast” lens in terms of aperture.

The manual focus ring is fairly narrow, and will be hard to find separately from the zoom ring if you are wearing gloves.  The damping is very light, but everything turns smoothly.  Focus seems to be linear and works fine, though without much tactile response due to the “focus-by-wire” nature of manual focus in mirrorless.  Some Sony lenses do a fairly good job of emulating manual focus, but this isn’t really one of them.

On a positive note, the lens does have dust and moisture sealing.  The build otherwise feels very much like a kit lens, and the $498 USD price for the lens feels a little steep for the lens based solely on the build and handling.  This feels more like a $200 lens.  Fortunately it is what’s inside that delivers the value.

The FE 28-60mm employs linear focus motors, and autofocus is fast, quiet, and accurate.

This lens does a nice job in video focus pulls, with quiet, smooth action that is aided by the fact that depth of field is never particularly shallow due to the smaller maximum aperture values.

Where I was most impressed, however, was in the optical performance.  The only real downside is some fairly strong barrel distortion at 28mm:

Though the barrel distortion is strong, it is nicely linear, so I was able to effect a perfect correction by dialing in a +23 in Lightroom.  The vignette was similarly fair strong, but a +40 and midpoint of 7 did the trick.  The upside here is that the fact that I can get a very clean manual correction of the flaws means that profile corrections (in camera for JPEG/Video and in software for RAW files) will also be very clean.

At 60mm the lens is essentially distortion free and has little vignette.  I did nothing to correct distortion and added only a +20 for vignette correction and then slid the midpoint over to 15 for a nice, linear correction.  All good news here.

At 28mm, the FE 28-60mm proves to be very sharp from wide open on.  It has high levels of contrast, great detail, and is consistently good across the frame.  There is little to no evidence of lateral chromatic aberrations, too, which will allow this to shine for landscape applications.  Here are greater than pixel level crops from the center, mid-frame, and corner:

I saw the same results in real world situations.  You can see from this shot and the crop that the detail and contrast are very high.

Stopping down to smaller apertures will give a slight boost in contrast, but performance is already high and just mildly improves.  Minimum aperture is F22, and, while there is a bit less contrast and detail isn’t as crisp, diffraction hasn’t done as much damage due to the lower resolution of the a7C.  The R series will give you more of a hit at apertures past F11.

Performance at 40mm was also excellent with very good levels of contrast and detail across the frame and a mild improvement at smaller apertures.  Choose F8 for peak performance across the frame.  Here are greater than pixel level crops from the center, mid-frame, and corner:

Here’s a wide open real world shot and crop, and it looks pretty good to me.

Minimum aperture is now F25, so you’ll see a bit more diffraction.

The high level of performance extends through to 60mm, which is outstanding even at F5.6 across the frame.  Here are greater than pixel level crops from the center, mid-frame, and corner:

Minimum aperture is now F32, so diffraction will be even stronger at F32.

Real world shots have great detail and contrast whether shot at close focus distances or landscape distances.

Here’s the framing difference between 28 and 60mm:

Even the bokeh is pretty decent, though you’ll have few situations where you can really “blow out” a background with a lens that tops out at 60mm and F5.6.

Minimum focus distance is 30cm, and the resulting maximum magnification is a fairly unimpressive 0.16x (this won’t be confused with a macro lens!), but this is compensated for somewhat by a good up close performance, which looked pretty yummy.

I was also fairly impressed with the flare resistance of the little lens (that does come without a lens hood), as it was able to shoot directly into the sun with little consequence in either loss of contrast or in ghosting and flaring.

All told, this is an impressive little lens optically, and I have to confess that it exceeded my expectations on virtually every level.  I was not impressed with the 28-70mm at all, so I was very pleasantly surprised by the fairly premium optics in this cheap housing.  The price of the lens drops to $300 if purchased in kit with the a7C, and I suspect that after market forces work for a while we may see the price drop further (the 28-70 costs $200 in kit).  Normally I wouldn’t advise people to purchase the kit lens, but this really isn’t a bad little compact option.  You can see more images from the lens in the image gallery here.

Conclusion

There was obviously a market for Sony’s compact full frame series considering that Sony has followed up the a7C with two different new models in the a7C2 and the a7CR. For some the greatest promise of the transition to mirrorless was the idea of smaller and lighter gear. The a7C series allows Sony shooters to really realize that vision, and there are more quality compact lenses available for Sony FE than probably any system has had before. The a7C2 makes it easy to travel light when you pair it with the right lens.

Sony has addressed a lot of the issues I raised with the handling and ergonomics of the a7C, and I appreciate the additional wheel and custom button along with Sony’s progress in their touch function on the LCD since the a7C. I still don’t love the placement and performance of the viewfinder, but that’s part of what allows the camera to be so compact. There are a variety of subtle improvements that make the a7C2 a better camera than the a7C was.

I was pleasantly surprised with the autofocus performance of the original a7C, and the a7C2 has improved pretty much everything in the autofocus department, with more autofocus points, new AI learning and tracking, and a better job of making the refinements available for both stills and video. Video performance is also enhanced with many more options and some higher end cine features now included.

The superior resolution is better suited to a modern camera, and I have found the 33MP resolution point to be really useful for a wide range of photographic pursuits. The bottom line is that the a7C2 is a clear upgrade over the original a7C in a lot of ways. I noted in my review of the a7IV (the camera the a7C2 is most based on) that Sony had moved the a7 series upmarket with the release of the a7IV, and the same is true of the a7C series with this release. But, like the a7IV, the price has moved upmarket as well, and the MSRP of nearly $2200 is a $400 premium over the original MSRP of the a7C…and $600 higher than what it is selling for now. You’ll have to decide whether or not the upgrades are worth the price, but there’s no question the a7C2 is a lot of camera…or a small amount of camera, depending on your perspective.

Pros:

  • Stays nearly as compact as the original
  • Ergonomic improvements – missing dial and buttons are now here
  • Improvements to the touchscreen make navigation easier
  • Love the ability to have a separate custom setup for video
  • Improved IBIS is top notch
  • Autofocus improved in every way
  • More AI tracking for both stills and video
  • Many more video options
  • Excellent dynamic range and high ISO performance
  • Higher resolution

Cons:

  • Buffer depth is diminished
  • Less battery life
  • Low light performance not quite as good
  • More expensive

Viltrox AF 20mm F2.8 STM Review

Dustin Abbott

November 7th, 2023

Viltrox has continued to hit their stride as a lens maker, and, while most of 2023 has been focused on more upscale lens options like the full frame 16mm F1.8 for Sony FE and the excellent Pro lineup for APS-C (the 27mm F1.2 and 75mm F1.2 lenses), Viltrox has managed to also deliver a very interesting lens for the budget side of the equation. The Viltrox AF 20mm F2.8 STM is a very interesting option for Sony FE, Nikon Z, and Fuji X mounts. It’s a wide angle prime lens with a moderately fast aperture of F2.8, but is also very compact (under 60mm long) and weighs only 157g. It also carries a price tag of just $158 USD, which you can lower another 8% by buying from Viltrox and using the code “DUSTINABBOTT”. That makes it an extremely affordable alternative to lenses like the Tamron 20mm F2.8 or even the Sony FE 20mm F1.8 G. But does the performance of the lens make it a worthwhile alternative? Find out my thoughts by watching the video review below…or just keep reading.

Thanks to Viltrox for sending me a review loaner of this lens. As always, this is a completely independent review. *The tests and most of the photos that I share as a part of my review cycle have been done with the Sony a7RV along with the Sony Alpha 1 that serve as my benchmark cameras for Sony lenses along with the Sony a7C2 that I happened to be reviewing at the same time.

__________________________________________________________________________________________________

As noted, the Viltrox AF 20mm will be available in three lens mount initially (my review has been done on Sony’s full frame E-mount), but one of those mounts is APS-C only (Fuji X). Fuji’s 1.5x APS-C crop means that the lens will have an effective focal length of 30mm, and, while that is less interesting than 20mm on full frame, it remains a useful focal length. Both Sony and Nikon also have APS-C cameras that share their respective mounts, so the compact size and low weight of the Viltrox AF 20mm makes it an interesting lens for APS-C there, too.

20mm is in the sweet spot for landscape type photography on full frame, with an angle of view of 91.6°. It allows you to get beautiful, dynamic images that really pop.

It just so happened that I received a loaner of the Sony a7C2 for review at the same time as the Viltrox, and it was a wonderful pairing for that compact camera. Many of the images shown in this review were taken with that lightweight combo. I would call the Viltrox AF 20mm F2.8 one of the best wide angle options currently available if you want to travel light. Why? Let’s dive into the details together and discover the reasons.

Viltrox AF 20mm F2.8 Build and Handling

Many of the recent Viltrox lenses have a metal, more hefty feel to them, but the Viltrox AF 20mm embraces a more conventional, lightweight design in polycarbonates (engineered plastics). The very first Viltrox lens I reviewed was a manual focus 20mm F1.8 lens, and that lens weighed in at a whopping 775g, or 618g heavier than this new lens. The new AF 20mm is a completely different kind of lens, only 65mm in diameter (2.6″) and 59.5mm in length (2.3″). It weighs only 157g (5.5oz). The strength of this lens will be the compact size, as it currently is (I believe) the smallest and lightest full frame 20mm lens on any of these mounts. Here’s a breakdown of the various specifications.

Up front we have a 52mm filter thread, which is a small but relatively common filter size.  The front of the lens fascia has a variety of information imprinted on it and has a classic profile. You’ll want to stick to slim filters to avoid adding any additional vignette.

There is a very slim lens hood included that bayonets into place but without as much precision and confidence as I would like. It doesn’t feel like it really “clicks” into place and locks in the right position. A lens pouch is also included. The pouch doesn’t add a lot of protection value, but, like the hood, at least it is included. There are many more expensive lenses that include neither a pouch or a hood.

In a rare departure for Viltrox’s autofocusing lenses, there is no aperture ring. There are no switches, either. The only feature on the lens barrel is a wide manual focus ring. The manual focus ring has a nice amount of damping and moves smoothly. All manual focus aids (including automatic magnification of the focus area) will work with the Viltrox.

The Viltrox AF 20mm employs a lower blade count in the aperture iris with 7 blades. I like a higher blade count on many lenses, but sometimes a lower blade count on a wide angle lens works better to produce cleaner sunstars.

The Viltrox AF 20mm is somewhat stuck in between, however, as the lower blade count keeps the aperture from being completely circular when stopped down, but I also don’t find the 14 pointed sunstars to have incredible definition (points to the rays).

We have an important Viltrox standard in the form a USB-C port on the metal lens mount that allows you to connect the lens to a computer and update the firmware directly.  I’ve been reviewing a prelease copy of the lens and Viltrox has actually done several firmware updates already to bring the lens up to release standards.

Viltrox lenses have traditionally had a fairly poor minimum focus distance and maximum magnification standard, but fortunately that is starting to change. The Viltrox AF 20mm has a minimum focus distance of 19cm and a respectable maximum magnification of 0.17x. That’s still behind the Sony 20mm F1.8 (0.20x) and definitely behind the Tamron 20mm F2.8 (0.50x), but it is high enough to be useful.

Before this year I had never seen a Viltrox with a magnification figure higher than 0.10x, so 0.17x sounds like a win. It’s enough to get close to a subject and blur out the background a bit.

While some Viltrox lenses have started to come with weather sealing, this inexpensive 20mm lens does not have it. It does have a HD Nano multilayer coating with water-resistant and antifouling coating on the front element.

The Viltrox AF 20mm F2.8 is a deviation from any of Viltrox’s current series of lenses. They have tended to produce lenses in series with common design elements, but I’m glad to see them diversifying. In 2023 they have produced both more premium lenses than anything they’ve previously made, but also produced this inexpensive, stripped down lens that will serve a different kind of audience. The biggest selling feature is the compact size and light weight. The lens is light but doesn’t feel cheap or flimsy. There are no bells and whistles here, but that’s okay at this price point.

Viltrox AF 20mm F2.8 STM Autofocus

The Viltrox AF 20mm STM utilizes a stepping focus motor (STM) that makes fast, quiet focus changes.  Focus felt silent unless I put my ear up next to the barrel, where I could hear some very light whirring during major focus changes.  When doing focus speed tests, I could feel inertia shifting in the lens, but there wasn’t anything to hear. I had no problem locking quickly on to subjects near or far.

I did a focus speed tests both indoors and outdoors and was generally impressed with focus speed and the confidence of focus acquisitions. Focus speed was nice and quick; not quite instant, but with no obvious lag between near and distance subjects. Viltrox has impressed me with how quickly they have learned how to do autofocus well. The Viltrox AF 20mm locked on focus quickly and accurately even when I was shooting a narrow subject matter.

I had no problem locking onto eye whether straight on or in profile, and my cameras’ “pose detect” AI seemed to work perfectly. You can see just how well focused the result is here:

The same positives apply to video AF. Autofocus continues to be silent during video focus pulls and pulls are quick and confident. No lag, no settling, and no sound. There is a fairly small amount of focus breathing that shouldn’t prove a problem for video shooters.

I didn’t have any issues with static video shots. There was no pulsing and focus stayed settled on the subject. When filming a trackable subject, focus stayed locked on the subject without any issue.

This will a solid lens for either gimbal work or vlogging. It’s very lightweight, allowing for a wider variety of gimbals to be used. It tracked effortless for a vlogging test I did, staying perfectly locked on my eye as I moved along or spun around. Here’s a screenshot from a vlogging sequence:

There isn’t much to complain about here for autofocus…particularly in such an inexpensive little lens. I don’t review on Nikon, but I suspect autofocus won’t be quite as robust on Fuji…particularly for video, but that’s more about Fuji’s autofocus being a bit less sophisticated. Here on Sony, however, I had a solid autofocus performance all around. As I moved around during video capture the lens stayed solidly locked onto my subject.

Kudos to Viltrox. There may not be many bells and whistles on the feature side of the equation, but this is a lens that functions well in the ways that matter most.

Viltrox AF 20mm F2.8 Image Quality

The Viltrox AF 20mm sports an optical formula with 10 elements in 8 groups. This includes 2 ED lenses, 1 HR element, and 2 aspherical elements. The MTF chart suggests good but not exceptional center sharpness with a steady decline towards the edges wide open and with a nice uptick in sharpness when stopped down.

As with the 28mm F1.8 that I recently reviewed, I felt like real world results were stronger than what the MTF suggests, though with one significant caveat that I’ll detail in just a moment. Real world results looked sharp and detailed across most of the frame with a bit of a dip in the corners.

We’ll work through the chart results by first looking at distortion and vignette.  Much like the 28mm F1.8 I just reviewed, there’s not a lot of distortion here, though what does exist is fairly complex. You essentially can’t correct it one direction without creating some distortion in another. For example, if I treat the distortion as pincushion distortion (a -2 correction in Lightroom’s Distortion slider), I can get the outside rectangle as close to straight as possible:

This comes at the cost of creating a bit of bulge in the inner lines, however. Alternatively, I can work at getting the inner lines as straight as possible by correcting for barrel distortion (a +9 correction). This has the negative effect of really exaggerating the distortion in the corners, however.

Bottom line is a correction profile tuned for this distortion is going to work best. Thankfully the quantity of distortion is quite low, and that means that you can mostly get away with leaving it uncorrected.

For context, however, at worst the Viltrox needed a +9 to correct the barrel distortion. The Tamron 20mm F2.8 OSD has an absolutely massive amount of barrel distortion, requiring a +42 to correct.

I definitely saw the distortion from the Tamron in the field, while with the Viltrox I shot scenes with square lines (like the interior of this barn), and the result looks fine without any kind of correction.

That being said, there is a significant amount of vignette. I used a +78 to correct, which points to about 3 stops in the corner. You are probably more likely to see uncorrected vignette than you are distortion in real world images. This image has not received correction for either:

At this point, Viltrox lenses aren’t receiving correction in camera for JPEGs or video.  I mostly shoot RAW images, so I don’t think about it much, but those of you who typically rely on in-camera corrections and shoot JPEG are going to be disappointed here.  My hope that is Viltrox gets to a place where they get more support and their lenses get in-camera corrections.  

The 20mm F2.8 showed relatively low amounts of longitudinal chromatic aberrations.  I saw very minimal amounts of fringing here.

That’s not really unusual for a wide angle lens with only a moderately large maximum aperture, but it does happen. Not having an issue with that allows you to shoot in high contrast situations without worrying about fringing.

If you look back earlier to the image of the barn interior, you’ll notice that the extremely high contrast of the light coming through the wooden slats shows very little fringing (even if I zoom into a pixel level). Many lenses I have reviewed would show a lot of fringing in that particular application.

Lateral Chromatic Aberrations usually show up along the edges of the frame as fringing on either side of high contrast areas (like bare branches framed at the edge of images), but that doesn’t seem to be an issue here. You can see a nice, neutral transition from black to white on the corners of my test chart.

So how about resolution and contrast?  All chart tests done with a Sony a7RV (61MP) using a tripod and a two second timer. Here’s a look at my test chart:

And here are the crops (at roughly 170% magnification) from the center, mid-frame, and extreme corner at F2.8:

The center looks excellent, with high acuity (a word I use to describe resolving fine details) and strong contrast. The midframe looks very good as well.

But the corners? Terrible.

Whenever I see such a big discrepancy between the midframe the corners in a way that the MTF chart doesn’t suggest, I start to try to diagnose why. I repeated the chart tests with identical results, so it wasn’t user error. I did notice that the corners don’t seem to be properly focused, so I redid the test with the focus in the corner:

Wow! That’s a night and day difference, obviously. But here’s the problem – if we look back to the center of these two images, here is what we find:

If you focus in the corner, the center is unfocused and soft. If you focus in the center, the corner is unfocused and soft.

Fortunately in the real world it isn’t quite so dire. It’s rare to shoot scenes where you need corner to corner focus at F2.8 anyway, and this field curvature issue is exaggerated by shooting at the very close distances for test charting. In a typical landscape image like this (shot on the Sony a7RV at F5.6), the corners are softer than the center, but not the mush we saw in the chart tests. They are acceptably sharp.

When shooting at larger apertures one is typically focusing on a subject, like in this shot of Nala.

Even when composed near the edge of the frame, the image is still sharp because the optics are sharp when the lens is properly focused in that zone.

Bottom line is that I don’t like this aspect of the lens, but it also may not be nearly as much of an issue in real world use. I will note that when I looked carefully at the centering of the lens using the corner focused results I did see good centering. By this I mean that I got equal results in all four corners of the image.

Stopping down to F4 showed an uptick in contrast and (to a lesser extent) resolution. You can see from this comparison in the midframe that contrast has significantly improved.

There’s a little bit more on tap if we stop on down to F5.6:

By F8 depth of field has increased enough that now the corners are starting to look pretty good even in the center focused tests.

After F8, diffraction will start to soften the image, though the effect isn’t as pronounced as on some lenses. The image is still pretty usable at the smallest aperture of F16, though I would say that sharpness and contrast peak at F8.

This inexpensive lens makes for a nice landscape lens. It’s a great focal length, and the light weight makes it a breeze to bring along as a compliment to something longer.

While wide angle lenses are rarely top options for getting strongly defocused backgrounds, but the reasonable close focus ability of the Viltrox AF 20mm does allow you to blur out the background somewhat.

There is a little more outlining of the bokeh than what I would like as it makes the background less creamy, but on the whole it isn’t bad. Here’s another where the bokeh looks pretty nice:

In this shot where a lot of the out of focus area is in the transition zone where it is not strongly defocused I find the quality of the bokeh to be a little jittery.

Color is subjective to some degree, but I didn’t notice anything unusual or off about the color rendering. It seemed reasonably neutral to me – neither garish or flat.

It’s currently late autumn in Ontario, Canada, where I live, which unfortunately lens itself to less color after the leaves have fallen. There are a lot of flat, grey days. It takes a little more work, but you can still find some interesting images.

Overall I found that colors seemed accurate and I was generally happy with the images that I got during my review period.

Flare resistance was fairly good but not exceptionally good. At all tested apertures contrast stayed good, but there is a flare/ghosting pattern that is faint at F2.8 but becomes more defined when the lens is stopped down. These various images show the little blobs of flare related color ghosting with different compositions. This is an area where the much more expensive Sony 20mm F1.8 G had a clear advantage.

It’s easy to produce good looking, detailed images with this lens, however, and that’s pretty impressive in such an inexpensive wide angle lens.

I personally find the combination of light weight, low price, and this optical performance to be a pretty compelling package. This lens feels as compelling as many lenses that I’ve reviewed costing 2-3 times as much. You can see more beautiful images by visiting the image gallery here.

Conclusion

The Viltrox AF 20mm F2.8 STM is a surprisingly interesting lens. It might get a little overlooked among the higher profile lenses from Viltrox this year, but the truth of the matter is that it actually fills a need. There are few lightweight, inexpensive lenses this wide. There’s the aforementioned Tamron 20mm F2.8 OSD, and, while that lens has some great strengths (high magnification, good price, good sharpness), it also has two serious flaws in the form of a less sophisticated focus motor and severe distortion. It also costs about $100 more than the Viltrox. The Viltrox compares even better to the Samyang AF 18mm F2.8, as while the Samyang offers a more compelling focus length, the Viltrox has a nicer build, better autofocus, and is sharper overall. The Samyang retails for $329 USD at the moment (both the Tamron and Samyang prices are sale prices), which makes the $150 price point of the Viltrox seem very compelling.

This is a great focal length for a lot of different applications, and I found it an easy lens to throw into the bag and bring along for a wider perspective.

I know that Viltrox has plans for even higher end lenses than their Pro series (rumored to be called their LAB series), and I’m very excited for those lenses. But I’m also excited about this lens, as there are plenty of potential customers who don’t have deep pockets but can benefit from a good performing, inexpensive prime lens. I also really liked the Viltrox AF 20mm F2.8 STM as a nice compliment to a compact camera like the Sony a7C2 that I used extensively in this review. It’s great to be able to travel light. I can’t think of a better wide angle option for $150 on any system.

Pros:

  • Lightweight, compact design
  • Well executed, smooth manual focus ring
  • USB-C port for firmware updates
  • Quick and quiet autofocus
  • Good focus accuracy
  • Good center and midframe sharpness wide open
  • Excellent sharpness across most of the the frame when stopped down
  • Fairly low distortion
  • Good color rendering
  • Fantastic price to performance ratio

Cons:

  • Field curvature makes it tough to get both center and corners sharp
  • Strong vignette
  • Distortion pattern a little complex
  • No weather sealing or features

Viltrox AF 20mm F2.8 Gallery

Dustin Abbott

November 7th, 2023

Viltrox has continued to hit their stride as a lens maker, and, while most of 2023 has been focused on more upscale lens options like the full frame 16mm F1.8 for Sony FE and the excellent Pro lineup for APS-C (the 27mm F1.2 and 75mm F1.2 lenses), Viltrox has managed to also deliver a very interesting lens for the budget side of the equation. The Viltrox AF 20mm F2.8 STM is a very interesting option for Sony FE, Nikon Z, and Fuji X mounts. It’s a wide angle prime lens with a moderately fast aperture of F2.8, but is also very compact (under 60mm long) and weighs only 157g. It also carries a price tag of just $158 USD, which you can lower another 8% by buying from Viltrox and using the code “DUSTINABBOTT”. That makes it an extremely affordable alternative to lenses like the Tamron 20mm F2.8 or even the Sony FE 20mm F1.8 G. But does the performance of the lens make it a worthwhile alternative? Find out my thoughts by watching my original video review or reading my text review. You can also enjoy the video below where I use the lens for travel and document my thoughts.
