This is a very important review for me. Not because the Nikkor Z 135mm F1.8 S Plena is a new and hot review (it was actually released in October of 2023, several months before I started to do Nikon reviews and 18 months before this review), but because it represents a very important new connection for me. Since adding my Z8 in spring of 2024 I have been seeking partnerships to get a supply of Nikon loaners here in Canada, but I was largely unsuccessful in my first year. That meant that I have largely reviewed third party Z mount lenses (Tamron, Viltrox, etc…) but only a few first party Nikkor lenses. But on a trip to Japan I developed a friendship with Evelyn Drake of The Camera Store TV on YouTube (a truly lovely person!), and she connected me with Chris at Nikon Canada.

Chris was kind enough to get me a loaner of the Plena, and its my hope that my connection to him will enable me to do a more thorough job of covering Nikon products moving ahead. So far he has been great, so thank you to both Chris and Evelyn!

The Plena 135mm is one of Nikon’s top tier premium prime lenses, engineered to produce as beautiful of bokeh as possible. It’s a lens that I’ve been wanting to test for a while, as I’ve had an opportunity to review (and own) a lot of other premium 135mm lenses over the years and have been very interested in Nikon’s offering. There’s also the factor that Viltrox has now released their 135mm F1.8 LAB lens in Nikon Z mount, (my review here), so for the first time the Plena 135mm has some real competition. There’s no question the LAB is a great lens, but having spent time with the two lenses side by side, there are definitely some areas where the extra polish and sophistication of the Plena shine through. The big question, however, is whether or not that difference is worth a $1600 USD premium, as the Plena costs a whopping $2500. The answer, as usual, is complicated, and really depends on your set of priorities. We’ll explore all those details in either the video review below or in this text review.

Thanks to Chris at Nikon Canada for sending me a review copy of this lens.   As always, this is a completely independent review.  All opinions and conclusions are my own. *The tests and most of the photos that I share as a part of my review cycle have been done with the 45MP Nikon Z8, which I reviewed here. You can find the product listing page for the Nikkor Z 135mm F1.8 S Plena here.

First, a word on 135mm lenses. There are few lenses that I like the look of images more from. To me images shot with a fast 135mm lens are a cut above those shot with an 85mm F1.4 (or even F1.2), but the challenge is that the additional 50mm in focal length makes for a less flexible tool. You need more room to operate, which means that a 135mm lens isn’t going to work in every room. I shot my first wedding using a Canon EF 135mm F2L lens rather than a 70-200mm type zoom, and I regretted it afterwards. There were several shots where the framing was unnatural because I didn’t have enough room to fit everything I wanted in the frame. But there’s no lens that I like more for environmental portraiture. The ability to have a full length portrait while still having beautiful separation of the subject from the background makes for incredibly special images.

There are sharp lenses and there are lenses with beautiful soft rendering…that creamy bokeh that we all love. Lenses that have both qualities are very rare, as it takes masterful engineering to accomplish this. Nikon’s engineers prioritized the rendering in the Plena, working to engineer right out to the edges of the frame. They wanted round specular highlights across the frame, low vignette so that it wouldn’t interfere with that rendering, and as generally pleasing bokeh as possible. One of the first banners on the listing page says, “Beauty that reaches every corner.” It’s that attention to detail that sets the Plena 135mm apart. This comparison hows that extra little something special when compared to the LAB, with rounder specular highlights right into the edges.

We’ll explore more of those little details in the review.

Nikkor Plena 135mm Build and Handling

Nikon’s lineup of Z-mount premium lenses – the S-Line lenses – is known for many things, but being small is not one of them. Nikon has taken the old Zeiss Otus philosophy where performance is by the greatest object and size and weight are not really significant considerations. I think they can get away with it, too, when they often have a Small | Medium | Large option at that given focal length. It’s true now of a 35mm, 50mm, and 85mm, where F1.8, F1.4, and F1.2 options all exist (though ironically the F1.4 options are often the smallest!). Obviously that’s not true of the 135mm focal length, where the Plena is the lone entry, but the Plena is definitely a part of the F1.2 crowd in design philosophy.

That being said, it’s not as if 135mm F1.8 lenses tend to be small and light in general, and while the Plena is a little wider in diameter than the Viltrox LAB option, it’s actually shorter and lighter.

The Plena is 98mm (3.9″) in diameter and 139.5mm (5.5″) in length. It weighs 995g (35oz). But the LAB 135Z manages to top that. It is 93mm in diameter (3.66″), a little narrower, but is a bit longer at 147.6mm (5.74″) in length. That’s not bigger (the Plena has an internal volume about 1% higher), but the Plena is actually lighter than the LAB. The Plena weighs 995g (35oz), which is heavy enough, but the LAB weighs a whopping 1268g (44.72oz), or about 270g more than the Plena. For that matter, the Plena is shorter and lighter than any of the S-Line F1.2 options. That’s right – the Plena is the lightweight option! It’s all about perspective.

What makes this a big, heavy lens is that there is a massive amount of glass inside right past those 82mm front filter threads.

The Plena is a premium lens with an excellent build. It has a tough outer shell of mostly metal alloys, and, internally, it has thorough weather sealing throughout.

There is a protective coating on the front and rear elements and then roughly 11 (by my count) internal seals at the rings, buttons, and switches. That allows you to have confidence when shooting in the elements.

I do have one gripe with modern 135mm lenses, and this criticism applies to all of them…not just the Plena. One of the things I appreciated about the old school Canon EF 135mm F2L (my first quality 135mm) was that it was fully compatible with teleconverters, allowing one to get a nice quality 190mm (ish) F2.8 lens with an F1.4x TC or even a 270mm F4 lens with a 2.0x. That just added to the versatility of the lens, but that seems to have be a forgotten element of modern 135mm design. Nikon instead touts that the rear element (located nearly flush with the mount, meaning that there is no physical room ever for a TC) is actually curved to allow for lower vignette.

At least this design has a specific purpose (more on that in the image quality section).

Nikon has a specific design ethos of the feature set of these upscale S-Line lenses, which includes a few more control points than the average lens. That starts very early on the lens with an AF | MF switch that is located very close to the lens mount.

Maybe too close to the lens mount, at least on certain cameras. On my Z8, there are two controls located way too close to this area. There is a flash sync port behind a rubber cover along with the camera release button. That means if I’m reaching around with my left thumb to operate the switch, I’m having to thread the needle through a couple of obstacles. Perhaps placing it on the same tier with the Fn buttons would have made more sense.

Next comes Nikon’s “clickless control ring”, which could serve as a manual aperture ring but could also function to control ISO, exposure compensation, or a few other functions – whatever you’ve set up the ring to do in the menus. Those controls can be found in the Custom Settings menu, then by selecting group F (Controls), and finally choosing custom setting F2 (Custom Controls Shooting) to change the function of the ring.

As an aside, I will note that I was able to do smooth aperture racks through the control ring without any visible steps. That wasn’t true of the LAB lens, where I could see visible steps even when I had the aperture ring in the declicked mode (at least on Z-mount).

The aperture iris has eleven rounded blades, and the aperture iris definitely does a nice job of keeping the specular highlights round. The screenshot above is somewhere around F5.6 or F6.3, and shows a very circular shape with very minimal evidence of the individual aperture blades.

Here’s what that aperture iris looks like from the inside.

I’m personally more a fan of a traditional manual aperture ring (with marked positions) as I think the function works better than using the control ring for aperture, where there is no natural visual representation of the current aperture. Unlike Sony (at least at the present), some of Nikon’s cameras have a top mounted LCD screen (including my Z8), which at least gives you some visual feedback on the current aperture. I can also appreciate that not everyone is a fan of manual aperture rings, and Nikkor’s approach allows that ring to be used for other purposes if so desired. Viltrox seems to have been taking a similar tack with their LAB lenses (and I’ve been complaining about it there, too!)

Many 135mm lenses employ a focus limiter switch, but Nikkor has skipped that on the Plena. The positive spin is that they clearly have confidence in the autofocus speed and don’t feel it is necessary.

In the middle of the lens there are two Fn buttons, one on the top and the other on the left side. These are redundant (both have the same function – whatever has been assigned to it in camera) but are in duplicate so that you have one easy to hand whether shooting in horizontal or vertical modes.

The manual focus ring is slightly raised and has a rubberized, ribbed texture.  It moves very smoothly and has a nice amount of weight to it. I was able to pull off really smooth manual focus pulls and focus with very nice precision. I also love the fact that I can do full time manual overrides even when in AF-C mode.

You’ll note that there is a third rubberized section near the front of the lens, but that appears to just be a grip section and not a movable part. It’s a rather odd design choice, actually.

There is no lens based stabilization, so you will need to rely upon the in-camera stabilization if your camera is so equipped.

The lens hood is relatively deep and does have a small lock on the right side. The hood is made of plastics and feels fairly ordinary. Unlike the Viltrox, it doesn’t have a rubberized front edge. I would argue that a premium lens like the Plena deserves a nicer hood.

Minimum focus distance is 82cm, giving a maximum magnification figure of 1:5, or 0.20x. That falls a little behind the LAB lens, which can focus 10cm closer and gives a 0.25x magnification. The performance of the Plena up close is fantastic even at F1.8, with excellent sharpness and contrast and a nicely flat plane of focus.

That excellent detail and contrast holds up well with a three-dimensional subject as well at minimum focus distances.

This is one other area where being able to throw on a teleconverter would be nice, as you could significantly boost that magnification into more macro territory.

There is no VR (vibration reduction, or optical stabilization) built into the lens. That’s not a problem on a body like my Z8, which has good camera based stabilization, but could be a problem for those of you shooting on a camera without VR.

I have loved using the word “Plena” as my keyword in this review. I wish that all lensmakers would apply a designated name to their premium lenses, as it becomes an easy way to distinguish it from alternatives and gives the lens a touch of elegance. The word “Plena” comes from a Latin word that means “full” or “complete”, and the latter meaning seems most appropriate. The words in nicely etched into the barrel of the lens and becomes a visual focalpoint for the lens design.

This is a big, heavy, expensive lens, but it is also beautifully made and is a nice match for a beefier camera like my Z8. It does carry a premium price at roughly $2500 USD, but it is also a premium product.

Autofocus (Stills)

I was a little surprised to see that the Plena employed dual STM focus motors, as I tend to associate Linear or VCM style motors with the more premium options. But having used the lens for a variety of applications, I’ve got no real reservations about the AF performance. Focus is very nicely reactive, able to keep up with more difficult subjects that I regularly photograph, including a fastly scampering little Nala.

I’m not sure if you’re aware, but cats are not very cooperative subjects. Most often when they are sitting nicely you can guarantee that they will start moving the moment you go to pick up a camera. Nala was perched on a planter in the sunshine, so I went to grab my Z8 with the Plena mounted on it, delighted to get a shot with her in a nice position. She immediately ran to the end of the planter and jumped off. I snapped a picture in frustration anyway, knowing that it would be out of focus.

But it wasn’t.

Not only was it not out of focus, but it was perfectly focused, despite her A) being backlight B) being on the move and C) my having no opportunity to start tracking and reacting properly to her movement. Here’s what a 100% crop looks like.

Now we’re talking!

So, autofocus speed belied my expectations of an STM-equipped lens. Maybe the solution is having two of them!

In my formal tests I saw mostly good speed, but I also a pretty consistent quick rack in the wrong direction before a then quick journey to the right focus destination. The Plena doesn’t seem to love those forced racks between a close and distant subject. In real world shots, however, focus changes tend to be smaller and I didn’t really notice the same things.

Focus accuracy was generally excellent in my tests. You can shoot with precision even in situations with a tiny depth of field, like this:

I did a portrait session with a friend (thanks, Justin!), and worked at a big range of focus distances – from a little over a meter to nearly 20 meters (4-55 feet). I switched between the Plena and the Viltrox LAB lens and had Justin hold poses so that I could get as scientific of results as possible. What I found as a general rule is that I had more consistent accuracy with the Plena than the Viltrox. That’s pretty much what you would expect, obviously, though I’m still waiting for the Viltrox to receive a firmware update that will hopefully improve the performance closer to what I saw on Sony FE.

I had very good focus results with the Plena whether working at close distances:

Medium distances:

…or further distances.

The only sequence that I saw some issues was in this one where some prominent branches sometimes confused the AF system.

Those of you who watched or read my initial review of the Viltrox LAB lens on Z-mount know that I had a similar problem there with snowflakes, so I think that Nikon’s Eye AF is just not quite as good at looking past obstacles as either Sony or Canon.

With a little persistence I got the result that I wanted here.

So autofocus for stills was generally very good. I wouldn’t put the Plena in the same class as a lens like the Sony FE 135mm F1.8 G Master, however, which utilizes dual XD Linear motors and has essentially flawless autofocus for both stills and video, but that’s not necessarily relevant on the Nikon platform.

Autofocus (Video)

Video autofocus was less impressive to me. Focus pulls felt a little rough, with plenty of little pulses, racks, and an end result that felt anything but cinematic. There’s a fairly strong amount of focus breathing as well (not unusual for a 135mm lens).

The focus breathing further detracts from the cinematic quality of video focus pulls. When I compared the LAB and Plena closely, however, it doesn’t seem like one is any better than the other.

Both also equally failed my hand test where I alternately block the view of the camera to my face with my hand and then remove it to test reactiveness. Neither lens decided to move from my face to my hand in any of the sequences.

Things were better when I approached the camera and stepped in and out of frame. They both did a pretty good job of moving focus on me when I approached in a linear fashion. With both lenses there was a pretty pronounced lag before focus snapped back into place on me if I stepped out of frame, however. I’d say the Plena was a couple of percentage points better, but neither was great.

The Plena did fine with static video shots where I just needed it to hold focus without pulsing or hunting. Overall video AF was probably the area where I was least impressed during my review, however.

Image Quality Breakdown

There’s rarely anything sharper than a good 135mm lens, and the Nikkor Z 135mm F1.8 S Plena is a sharp one. The optical design is 16 elements in 14 groups, and as you can see from the cutout below, six of those are exotic elements including Aspherical, ED (extra-low dispersion), and SR (short wave refractive) elements. The MTF shows a 90% mark across about half the frame and then a slow slide to the corners at F1.8.

On paper, the Viltrox LAB is the sharper lens.

But we’ll verify (or dispute) that for ourselves.

One of the big marketing points by Nikon is that the Plena has been designed with a unique rear element that is both larger and curved, allowed light to more evenly illuminate the whole image circle. And, when examining the my chart results, I found that the Plena showed very low vignette.

I used about a stop of correction here (+30), and even that is gone by F2.8. There’s a tiny bit of pincushion distortion that corrected easily with a -3.

That means that real world results at F1.8 even without correction are going to have an essentially invisible amount of vignette, like this (uncorrected result – no profiles or manual correction).

This was also the way that I found the LAB on Sony, but that’s just not the case on Z-mount. The Viltrox lens shows a lot of vignette on the larger diameter Z-mount.

For perspective, I needed +50 to correct the vignette on the Z-mount version of the LAB, or nearly twice as much. There is no distortion on the LAB lens.

I also saw very minimal amounts of LoCA (longitudinal chromatic aberrations), and that is the case here. I see mostly neutral results on either side of the plane of focus with only a tiny amount of fringing after the lane of focus.

This real world result shows no visible fringing before or after the plane of focus.

Brilliant.

LaCA (lateral chromatic aberrations) typically show up along the edges of the frame with high contrast transition points.  I saw nothing but clean transitions on either side of the black and white transitions.

So far those are all really excellent results.

We’ll move on to inspecting our test chart.  This test has been done on a 45MP Nikon Z8 sensor.  I use a high end tripod and two second camera delay to ensure vibration doesn’t affect images.  Here’s a look at the test chart that we will examine at high magnification:

If we take a look at crops (at 200%) at F1.8 from the center, mid-frame, and lower right corner, we find that center and mid-frame performance is exceptionally good, and that sharpness extends right to the corners.

If I compare my chart results with those I’ve done with the LAB, I find that I prefer the Plena in the center, the LAB in the mid-frame, and it is mostly a wash in the corners.

If I compared the two lenses for portraits, I had a hard time picking a winner. They both gave essentially equal amount of contrast and detail, and even skin tones look pretty similar. The LAB lens may give very slightly deeper levels of saturation, but they are very, very close.

If we step back and look at the image as a whole, there is again very little to distinguish between the two lenses.

One more interesting comparison is a full length F1.8 shot with a lot going on in the scene. I’ll let you spend the time trying to find the differences; they aren’t easy to spot.

Now, before you get too bent out of shape, know that Sony shooters have already dealt with the same angst, as, if anything, the Plena actually outperforms the Sony GM. The LAB lens is just shockingly sharp for the price.

Stopping the Plena down to F2 produces a slight contrast boost across the frame, but probably not enough that you would notice without them side by side and at high levels of magnification. That’s not true at F2.8, however, where the improvement is far more noticeable…particularly in the corners, which are now razer sharp.

If we jump back to a real world result, we will find that sharpness and contrast are just gorgeous…as is the general rendering from the lens. As mentioned in the intro, this is one of those rare lenses that has both gorgeous defocused rendering and razer sharp detail/contrast.

Look at the amount of detail in Justin’s beard and mustache.

After F2.8, it is hard to tell much of a difference through F8. It’s just amazingly good all throughout. Landscape images are going to be pretty flawless.

Physics will affect even the mightiest of lenses, however, so expect diffraction to start to soften the image by F11 and more obviously by F16, which is minimum aperture (though this lens is still sharper than many lenses at its weakest!)

But the Plena isn’t all about sharpness. Bokeh is at the heart of its design. It is very easy to get extremely pleasing backgrounds with very creamy defocus and great colors.

You also get great subject separation, with an excellent level of 3D subject isolation.

I brought along a vintage hatchet to the photo shoot with Justin, not really knowing how I’d use it but grabbed it on a whim. It turned out that the area we went to had just had some clearing along the path, and the heavy machinery had just chewed everything into splinters. I knew exactly how the hatchet would work, and got Justin in the midst of the carnage as if he’d done it all with the hatchet. See the amazing cutout effect effect that you can achieve even at a distance?

I was using natural light for these shots, but if I had used strobes, it would have seemed essentially like I had “Photoshopped” him into the scene as strobes will often just intensify the cutout effect.

Part of that rear element design was not just about vignette, but also about being able to evenly distribute light for the sake of specular highlights. And there is no question that the Plena is the best 135mm lens that I’ve used for keeping circular specular shapes (bokeh balls) right into the corners even at F1.8.

The bokeh rendering is fantastic from the 135mm Plena.

I only have one optical complaint, and it is more of a general Nikon complaint. I find magentas a little too strong, so I find that in Caucasian skin tones that I often feel that I need to take some of the red/magenta out of people’s faces.

Darker skin tones look more natural to me.

Cat fur tones are also excellent, and I just love the amount of sharpness and contrast I get from the Plena.

Flare resistance was also very strong on the Plena. I didn’t see any lost of contrast in real world shots, and here you can see with the sun in the variety of positions and with a variety of apertures (from F1.8 to F11) that there is never really any veiling, either. The various coatings by Nikkor (Meso Amorphous Coat and ARNEO Coat) are doing a fantastic job.

The Plena thrives in all tested metrics. This is one the good ones.

The bottom line is that this is one the most complete lenses that I’ve tested optically, with strong performances in basically every optical category. If you’d like to see more images in my extensive image gallery, just click here.

Conclusion

Nikon’s premium S-Line lenses represent the pinnacle of their Z-mount engineering, and the Nikkor Z 135mm F1.8 S Plena is one of the best. It has it all going optically – great sharpness, great bokeh, and no real aberrations or flaws.

The only fly in the ointment is the new Viltrox AF 135mm F1.8 LAB Z, as it shares a lot of those optical strengths and comes at a much lower price tag. But as I used the two lenses side by side, I could see the many little ways where the Plena proved its superiority. It just works better, whether it was doing aperture racks, getting better consistency when doing portraits, or even manually focusing.

The Plena is still the premium option, however, with an amazing performance all around. It produces the kinds of images that you can only associate with professional photography, and you won’t ever have to worry about someone’s phone producing images that look like your 2 kilo combination of Z8/Z9 and the Plena. If you are a portrait photographer (particularly if you do environmental portraits) and you want a lens that can reliably produce images that you’ll love, then check out the Plena. It’s a treat.
