Hi, I'm Dustin Abbott and I'm here today to give you the first of a two-part series taking a look at the image quality
0:13
comparisons between the 24 to 70 millimeter F2.8 Gmaster lens from Sony, which comes in at about $2,200
0:22
And the brand new Tamron 28 to 75 millimeter F2.8 RXD lens for Sony
0:29
Sony F E and this one comes in at $800. So of course, you know, you might say, well that begs the question
0:38
why are you comparing a $2,200 lens with an $800 lens? It's almost a third of the price
0:44
And of course, the reason is that there really aren't a whole lot of options
0:48
for lenses like this on Sony F.E mount. And so this is really going to be a lens that a lot of shoppers
0:55
particularly those that are budget conscious, are going to be cross-shopping with the G-Mount
0:59
with the G master lens, which to this point has been the only real, you know, kind of
1:04
professional grade F2.8 zoom that covers this focal length. Now in terms of the focal length, number one, I do want to point out that a 28 to 75
1:14
millimeter lens is not a 24 to 70 millimeter lens, as we're going to see in the comparison
1:20
that we're about to jump into. The reality is, is that a lens going to 24 millimeters of focal length requires a lot more
1:28
engineering and as you can see it also takes a lot more size and heft involved
1:35
with it and we talked about that deep those details in the first episode of
1:39
comparison where we broke down the building the design of the new Tamron as a
1:44
part of that but as you can see even in this quick visual comparison the G master
1:48
lens is huge compared to the Tamron lens which while it's kind of long and
1:53
slender it's really still a reasonably compact lens and just on a practical
1:57
level where I note things like that is that for example I'm in the process of
2:02
reviewing this peak design everyday sling bag it's the 5L and I already own the
2:07
20 L backpack I really like it so I'm trying out this everyday sling right now so I
2:12
noted that for example I can have the A7 R mark three with the tamron attached
2:17
and I can actually mount it face down into the bag and of course have lots of
2:21
room for other lenses clearly that's not going to be happening with the G master
2:27
lens which is a fair bit larger all around and so it's just some of those little things to
2:32
where the tamron you know is a little bit more of a convenient choice but it's not 24 to 70
2:38
millimeters now I'll break down a little bit more how some of these things play out in the second
2:42
episode in the second episode I'm going to be looking at things like more things like color
2:47
rendition and bouquet quality I'm going to be looking at microcontrast with real everyday
2:52
three-dimensional objects you know and even throw in a portrait comparison there, some of those other metrics. Today we're going to be looking just at resolution. And how do
3:02
these two lenses shape out both at a kind of a portrait distance and then at infinity distance
3:10
if you're wanting to shoot, or a landscape distance, I should say. And so we're going to jump in and
3:14
look at a visual comparison. And this is going to be detailed. Just, you know, stay tuned for a little
3:19
bit. But you're going to find this is probably going to be the most detailed comparison that you've
3:23
seen yet on this new Tamron. So let's jump in. Let's take you. a look
3:28
We're going to start by looking at the image at 28 millimeters out of the new Tamron, 28 to 75
3:34
millimeter for Sony FE. So one thing you're going to note, looking at the image on the left is you most certainly
3:40
have some rather pronounced barrel distortion that's taking place here. And so you can see a pretty strong bulge in what should be the straight lines along the edge
3:53
Now on the right, while there isn't yet a profile in. Lightroom or Adobe for full correction
3:59
I found that just a few minor tweaks through some just manual corrections
4:05
eliminated most of the distortion here. I think you can see maybe just the slightest
4:11
bit of a curve that still left her along the top. But I think that throughout the image
4:16
that's not a difficult correction. All of the lines look acceptable at this point
4:21
Now for those of you interested in seeing what I did here to correct this
4:25
I dialed in under the manual correction. under lens corrections, I dialed in a 10 on distortion
4:31
and then I did a 26 on vignette and moved the midpoint to 18
4:36
And as you can see, that's resulted in a pretty even illumination across the frame
4:42
So the first comparison to note is that the 24 millimeters on the GM lens
4:47
is a whole lot wider than the 28 millimeters on the Tamron
4:52
And so, I mean, if you're, you know, your priority is getting
4:56
lens it also goes quite wide, then obviously the GM lens does a lot better job of getting to 24
5:04
millimeters than what the Tamron does. And as you can see that four millimeters, it may not sound like
5:09
a lot, but in the real world, that represents a lot of additional image. So as you can see
5:14
looking at the image from the GM lens, certainly it has just as much, if not more barrel distortion
5:21
wide open here. And so, I mean, that's not necessarily an advantage
5:27
Just taking a quick look, I'll do a more detailed comparison at 24 millimeters
5:32
But let's take a look at, or excuse me, at 28 millimeters. But at 24 millimeters versus 28 millimeters, Tamron's going to be on the left during this
5:40
A couple of things to note. Number one, is we're going to see as a trend
5:46
I think the light transmission favors the GM lens. It just seems a little bit, a little more light
5:51
light in. And of course, it has an 82 millimeter front filter thread
5:55
and thus a much larger entrance pupil compared to the 67 millimeter on the Tamron And so it definitely delivers a brighter image at equal settings What we can also see however is that center of the frame
6:08
the Tamron actually probably has a little bit more contrast and punch
6:13
You've got great correction on the Sony lens. The Tamron, though, has a little bit more nuanced delivery here
6:21
Now, as we move off towards the edge of the frame, and of course, edges aren't completely apples to apples at 24 versus
6:27
28. But you can see that the GM lens is doing a better job of maintaining a sharpness off towards
6:35
the edge. And, you know, neither one of them is necessarily exceptional here at the very edge of the
6:41
frame. But we can see that it does slightly favor the GM lens on the edge of the frame
6:48
Now, if we can compare 28 millimeters versus 28 millimeters, we're going to find that at 28 millimeters
6:54
the distortion pattern has started to diminish on the Gmaster lens, and so it is delivering a, you know, just a more geometrically correct image
7:05
than what the Tamron is. We can see, once again, even with equal settings
7:08
obviously you have a much brighter image from the GM lens. You also have a different in the interpretation of color
7:16
and I would say, as we're going to see more in kind of a future episode
7:21
and that there actually is more color saturation for the Tamron lens
7:26
than what there is for the Gmaster lens. So taking a look at center sharpness
7:31
what we're going to find is that while they're not hugely different
7:36
I think you could definitely argue that there is more detail and definitely more microcontrast on the Tamron lens at the center of the frame
7:45
But as we begin to move towards the left edge of the frame, we're finding that the Gmaster lens
7:51
lens is definitely stronger off towards the edge of the frame at 28 millimeters and
7:56
that's true on both sides of the frame to roughly equal amounts and so center
8:01
sharpness favors the Tamron but edge sharpness definitely favors the G master
8:06
as does the amount of kind of correctness to the image now if we stop them
8:11
both down to F5.6 maybe a more traditional landscape aperture we're going to find
8:17
that looking at the center of the frame we have got roughly similar results
8:24
I mean, they're basically so similar in terms of contrast and resolution that I think you would be hard pressed
8:32
to see a difference between them in the field in the center of the frame. So we move off towards the edge of the frame
8:39
however, while it's not a large margin necessarily, the Gmaster is definitely the better performer
8:45
towards the edge of the frame. And so that's true wide open. It's also true with the two lenses
8:50
stop down. And of course at 28 millimeters because the G master is engineered to go all the way to 24
8:57
millimeters, we're also seeing that there is less distortion that's taking place. And so end product is that
9:03
you have a better edge performance, stop down with a nearly identical center performance at
9:09
28 millimeters between the two lenses. Now at 50 millimeters, both lenses are showing a bit of a pin cushion
9:16
distortion that you can see here and here. And I would say it's maybe a little bit more pronounced
9:25
on the Gmaster lens and what it is on the Tamron. Once again, a light transmission and just kind of
9:31
general brightness, illumination across the frame, wide open favors, the Gmaster lens. Now in terms of
9:37
our resolution here, we have what I would say is the strongest advantage for the Tamron in the
9:43
center of the frame performance. And that it's deliberately, delivering a brilliantly sharp middle of the frame performance
9:50
Whereas the Gmaster, this appears to be probably the weakest point of it optically than what is what I've seen
9:56
And off to the edge of the frame, there's, frankly, there's not a lot to distinguish the two
10:03
I'm going to give a very slight edge to the Gmaster. Neither of them look incredible along the edge of the frame
10:09
And here again at the side of the frame on the right side, they look more similar than different
10:14
But I think that there is just, there's a little bit better contrast, just a little bit of a kind of a haze that is there, kind of a veiling that's on the Tamron that's not on the Gmaster at the very edge of the frame
10:28
Now, if we stop them both down to F5.6, we see once again at, you know, a more traditional landscape aperture
10:35
Things have really, really sharpened up for the Gmaster. The Tamron also looks equally good right at the center of the frame
10:42
but if you begin to move off center even a little bit, you see that the advantage now favors the Gmaster
10:48
and that it has more resolution to bring to the table when stopped down
10:52
than what the Tamron does. So the Tamron delivers a pretty strong across the focal length
10:57
delivers a strong center of the frame, wide open performance, but when stopped down
11:03
it's definitely not making the improvements, particularly at the edge of the frame that the Gmaster lens is
11:09
Now at 75 or 70 millimeters, whatever the case may be here, a few things to observe
11:15
The vignette pattern on the Tamron is fairly strongly pronounced, and definitely more so than what you're seeing on the Gmaster
11:23
The Gmaster is exhibiting more pincushion distortion than what the Tamron is
11:28
Its distortion is fairly neutral. I do see just the slightest hint of pincushion
11:34
but I definitely see more of it on the Gmaster lens. Now, in the center of the frame
11:39
both of them are delivering a roughly similar, result but I do if you look at this line across here you can see that the G master is a little bit better corrected and thus there is there not any kind of veiling The edge is a little less distinguishable here on the Tamron lens and that is due to a little bit of veiling Also if you take a look at this kind of natural patterning in the the stone there you see that the microcontrast on the G master lens looks better and so that looks a little bit more three than what it does here on the Tamron
12:12
We move off to the edge of the frame. A familiar pattern in that the Gmaster is better, though it's
12:18
not better by a huge margin, but definitely edge of frame performance wide open favors Gmaster
12:25
Now with the lenses stop down to F5.6, we're going to see, you know, somewhat
12:30
similar patterns. Gmaster does a great job when stopped down. I mean, it looks, you know
12:35
incredibly, incredibly sharp there. Contrast looks very good along this. And, you know
12:41
resolution is pretty similar for the Tamron. Contrast, I think, favors the Gmaster a little bit
12:47
Moving off towards the edge of the frame here. You know, frankly, there isn't a huge amount of
12:53
difference. I do think there's a little bit more contrast. If you look at this kind of grout area
12:57
here. You can just see a more three-dimensional result from the Gmaster than you can on the Tam Run
13:03
It's, you know, it's definitely there. And so it's not, again, it's not by a huge margin
13:10
but I definitely favor the Gmaster performance stop down. Now, if we go out into an infinity
13:16
type scene, a couple of observations to make. Once again, as we saw with the results on the
13:23
on our wall test, we see that there's definitely a difference in the interpretation of color and that the the g master lens is a
13:33
little bit cooler the tamron is a little bit warmer now when it comes to dealing
13:37
with greens this may be a taste related thing so which which you favor will
13:43
depend down on your interpretation of course some of this you can tweak and
13:46
post now if you're interested in knowing whether or not it's just a matter of
13:50
white balance and the way that the you know the the lens kind of instructs the
13:55
camera to record white balance. Reality is they actually delivered an almost identical white balance
14:01
The Gmaster lens delivered a 5,700 Kelvin with a shift to plus 11 and the Tamron lens delivered
14:13
a 5600 with a plus 11. And so in this case I've actually brought the Tamron up to 5,700, which of course it actually
14:22
just makes it a little bit warmer. And so it's definitely a difference in the glass itself
14:27
And so again, tasting. Now in terms of looking at the sharpness itself
14:33
center of the frame wide open here, there is, as we saw before
14:38
there's really not a whole lot to distinguish the two lenses. I mean, they're delivering a very, very similar performance
14:45
in the center of the frame. I do think that the microcontrast here favors
14:50
the Sony, the Gmaster lens. And as you start to move off
14:54
center. What you're going to see is, as we saw with the brick wall test, the Sony does better as you
15:00
get out towards the edge of the frame, and it just delivers a stronger performance. Looking back here
15:04
at a global level, you can see it also delivers a much wider at 24 millimeters. It's delivering a much
15:11
wider than the 28 millimeters. So that's certainly a factor. Looking at this side edge of the frame
15:18
you can just see that some of these textures are a little bit muddier, and they're a little more sharply pronounced here
15:23
on the Gmaster lens. And so it's definitely, I would say, the stronger landscape lens
15:28
Now, if we stop them both down to F5.6, what we find is that center of the frame
15:34
you know, once again, it's in a landscape setting, I don't think that you can really tell a difference there
15:40
Now we're seeing a little better microcontrast, you know, on this kind of bare-limbed tree
15:47
But as I look at, say, the texture in this, you know, smaller tree area here
15:52
you can see there's just a little bit better result on the Sony. We move off to the edge of the frame and you know the Sony
15:58
sharpens down really great for a landscape type work here whereas the Tamron is
16:04
just not as compelling at the edges of the frame and so once again you know
16:09
looking at this versus this the margin may not be as big as it what it was before
16:14
but if anything the Sony makes as much or more significant gains when stopped
16:19
down compared to the Tamron at edges of the frame. So in our brick wall test we
16:23
that the tamron was particularly strong at 50 millimeters and so let's see how that compares at landscape
16:30
distances what we're going to find is that the tamron does look a little bit sharper a little
16:36
crisper in some of these textures and details if you look at the needles here compared to the gmaster
16:41
they're a little better defined on the tamron at the center of the frame now as we move off center
16:47
even a little bit to you know that bare tree which is a great kind of texture test along with the
16:53
next to it, we see that the Tamron's gain or advantage is very much reserved to the center of the
16:59
frame. And the Gmaster, it begins to show its superiority at the edge of the frame performance
17:06
in a significant way. And, you know, for example, if we compare these two trees here, while it's not a
17:13
huge difference, you can definitely see more microcontrast on the Gmaster at F2.8. Okay, with them both
17:19
stop down to F5.6. As we saw before, the Gmaster making... some really great gains in its center of the frame performance when stopped down
17:30
It's not enough to make it notably better, but you can see if you look right in this area
17:36
compared to here, a little bit better contrast and details are just more finely rendered
17:42
as opposed to the Tamron. And of course, the further you move along here, the more obvious that becomes
17:47
The GMaster sharpens down great towards edge of the frame, whereas the Tamron is just not holding up
17:53
in terms of the raw resolution towards the edges of the frame
17:57
On the right side, I think it's maybe a little less pronounced
18:01
The Tamron seems to be a little stronger on the right side both in the brick wall test and here But at the same time I do think that the G master is the stronger of the two
18:12
So the first thing I wanna point out is that at 75 millimeters versus 70 millimeters
18:18
the Tamron definitely is zoomed in further. And you can see that quite notably
18:22
if you look at this area here versus, you know, it's showing up much more on the Sony
18:29
Not a huge difference on the right side, but here on the left side, frame. You can see, for example, that this bear tree is much closer to the edge of the frame
18:36
than what it is on the Sony. That being said, I think that we can all agree that the focal length
18:42
difference at 75 millimeters versus 70 millimeters is not as significant as the focal length difference was
18:49
at 24 versus 28 millimeters. I would say for myself, the extra 4 millimeters on the wide end would make
18:56
a much bigger difference to my day-to-day shooting than would the 5 millimeters at the end of
19:02
the focal length. Now, going beyond that, one thing you might have noted when we zoomed into this
19:08
is that center of the frame at 75 millimeters, we've definitely got a stronger looking result from
19:13
the Tamron here. Looking at the very center of the frame, textures in these needles, and there's a lot
19:19
of fine details there, but they're just a little better rendered in the center of the frame
19:23
you know, very center of the frame on the Tamron than what they are on the Sony. However
19:29
moving off to the edge of the frame, the Sony is a, little bit better, although in this case, I don't think that it's hugely better. If we look over at
19:38
the other side of the frame, again, it's more similar than different, a little bit better microcontrast
19:45
on the Sony lens than what there is on the Tamron lens. Not a significant difference though
19:50
with both them at the long end of their focal length at wide open. With both lenses stop down to
19:57
more typical landscape apertures, we can see that they're now both delivering quite a brilliant
20:02
sharply sharp result. Right here at this portion of the frame, I would still very, very, very
20:07
slightly favor the Tamron, although it's, without having them side by side, you wouldn't be
20:12
able to tell the difference. Center of the frame, both of them are delivering a just a brilliant
20:17
result. Lots of detail. Looks great. Moving off towards the side of the frame, once again, it's
20:24
it's not really a big enough difference to note much here on the left portion of the frame. Maybe
20:31
G Master, but not enough again in fuel conditions to tell the difference. So at 75 versus 70 millimeters
20:39
at landscape distances, the Tamron is holding its own against the Gmaster. The best is what we've
20:44
seen in the focal range. And while I do think the Gmaster is ever so slightly better in terms of
20:52
its microcontrast, it is, you know, within the margin of error, there's not much difference
20:58
And so as you can see, you know, there's There's pros and cons for both
21:03
I would say in an absolute sense, the G-master is the stronger lens
21:08
but it's really only the stronger lens and the outer portion of the frame
21:12
And so if you're kind of determining resolution-wise whether the Tamron is going to work for you
21:17
I think the question to ask yourself, the first question maybe, is what is your shooting style entail
21:23
If you're primarily shooting things that fit within the middle half of the image circle
21:29
you're not only going to get as good of reason, as with the much more expensive Gmaster lens
21:33
you may even get better results, depending on the focal length. But if your compositions are more about landscape orientation
21:40
I would say the G master is the better lens for that
21:44
And so I would say yes, in an absolute sense, the G master is the stronger lens
21:49
In terms of pure resolution, you're going to have to determine for yourself
21:53
whether or not it is nearly three times as good for you, if that extra little degree of edge sharpness is enough to make the dead
22:00
enough to make the difference for you. Of course there's more to be determined here than just
22:05
resolution alone. And that's why we're going to come back with a subsequent episode on that
22:09
And then my final review of the Tamron, yes, I will be addressing autofocus, but I'll also say
22:14
two things on that note. Number one, Tamron is in the process of rolling out a firmware update
22:20
to solve an autofocus issue. This is a fully first-party compatible like lens in that it will be
22:28
updated just during through a firmware packet through your Sony camera body just like any first
22:34
party lens would be the second thing on that is that I've done everything I could to recreate
22:39
the issue that the internet has been buzzing about and at least with the review copy I have I have been
22:44
unable to recreate that issue so for me it's been a complete non-issue and so I can't really report
22:51
on the issue because I haven't seen it at all so stay tuned and I'll be following up with
22:55
subsequent image quality episode shortly along with with a final verdict on the new Tamron lens
23:01
I'll do a little bit of autofocus tracking with it with the two lenses, see how they compare
23:05
shoot some portraits, all of that, so stay tuned. In the meantime, if you look in the description down below, a couple of things happening there
23:13
Number one, you can take a look at linkage to the image gallery where I've been adding images
23:17
to taken with the A7R3 and the A73 and the 28 to 75 Tamron
23:24
You can also find a order link there. And on that note, my sources within Tamron tell me that expect for a while for demand to outstrip supply
23:35
This is going to be a very popular lens. And at the moment, there are a lot more orders for the lens and there are lenses available
23:42
I say that to say that if you are considering getting the Tamron, you might want to consider getting an order in to get yourself in the queue for it
