Hi, I'm Dustin Abbott, and whenever I do comparison videos, I always get a number of requests to, of course, add even more different lenses for comparison
0:16
And some of those can get a little bit extreme. But today I want to give a shout out to one of my viewers, Paul O'Neill from the Toronto area in Canada
0:24
And when he wanted to see a comparison to the 2470 G2 with the Canon 24 to 70 L Mark 2
0:32
and knowing that my window was closing and I wasn't going to be able to really get one of those lenses in
0:38
he actually shipped me his own copy of the Canon 24 to 70 L Mark 2
0:44
And so thanks to Paul today, you all are going to get to see a comparison between the Canon lens
0:50
the new Sigma 24 to 70 art, and then of course the new Tamron
0:54
24 to 70 F2.2.G2 lens. And so we're going to jump in and we're going to shoot a series of comparisons
1:02
Here at this setting, I'm going to shoot some infinity work and then I'll shoot the barn wall
1:07
that I like to shoot that gives me a lot of texture information to compare
1:11
We're going to see how image sharpness carries out. But when I come back to do my wrap-up, I'm also going to share some observations from Paul
1:19
himself who owns this lens and how that it performs better in one situation
1:24
than it does in another, and we're going to find out why. So let's jump in. Let's take a look
1:29
All right, so here's the comparison you've all been waiting for. Now, I have heard some reviewers say that while the new, you know, Tamara on 24 to 70 G2
1:38
or the Sigma 24 to 70 art lens, that, you know, they're certainly priced well
1:44
and, you know, they're a good alternative price-wise, but you're going to get the best image
1:49
quality still with the first-party lenses. We're here to determine whether or not that that's true today
1:54
And so we'll compare, kind of back to back, we'll compare the new Tamron 24 to 70 F2.8 and the Canon 24 to 70 F2. L mark 2
2:07
And then of course we'll compare also with the Sigma 24 to 70 F2.8 art lens
2:14
So here we go. Let's get a few things globally here. I'm going to note that I think that there is a bit more barrel distortion on the Tamron lens on the left than what I see
2:24
on the cannon on the right, not, you know, in a hugely noticeable way, but just a slight bit more
2:30
of a bulge here in the center. And then the other question I want to look at as we go through the
2:35
various focal links is when it comes to framing, and thus some of you might have some concerns
2:41
about focus breathing. So we'll look at that as well. Now, just to give you an idea of what I've done
2:45
I shot all of these in raw to make sure that there was no kind of digital trickery that was done
2:51
that might favor the first-party lens. And then all I've done, done is I've output them into fairly large JPEG files. So as we look at the images here
3:03
we're going to see that the Tamron is actually framing a little bit wider on the right hand
3:10
And then if we look over on the left hand, it is framing about similarly. And so thus
3:16
I would say that you're actually getting a little bit more than 24 millimeters, at least compared
3:21
to the cannon. And so that's a... net positive for the Tamron here you want as wide as possible
3:28
Now, looking in the center of the frame, we're going to find that there is definitely a
3:33
bit of an advantage for the Canon lens. It has just a little bit more resolution, and then also it has a little bit better contrast
3:41
center of the frame. Moving off towards the edge of the frame, once again, there is an edge for the canon, although
3:50
towards the edge of the frame, it is, you know, it's not very significant
3:54
at all. And looking over on the right side of the frame, we see, you know, pretty much the same story
4:00
except for I definitely do favor the Canon lens. So now we've got the Sigma lens on the left, 24 millimeters
4:06
Now, one thing you're going to notice that as a trend that I also want to point out as a global thing
4:13
the Canon and the Tamron exposed here at 1 to 50th of a second to get the same exposure on the Sigma
4:20
required a 1-200th of a second. So at 24 millimeters, it does
4:24
definitely doesn't have as good of light transmission. Looking at the center of the frame
4:30
the, you know, once again, the cannon definitely shows more fine detail
4:34
Contrast is pretty good on the sigma lens, but the resolution isn quite as high Moving off towards the edge of the frame however here the kind of the weakness of the sigma is exposed Its sharpness really at 24 millimeters does not reach the
4:50
edge of the frame, and that's been consistent in all of my test. A pretty strong win for the
4:55
cannon there. Looking at this side, the same is true. So contrast, nice on the sigma, light
5:02
transmission is a little bit weaker, but resolution at F2.8, 24 millimeters, favors the cannon, and so wide
5:10
open it is Canon, second Tamron, third Sigma. Okay now if we move both of these to F4
5:18
jumping into the center of the frame, we're now going to find that the Tamron has
5:23
sharpened up and added contrast in a major way and now it looks equally as good, even a bit
5:30
more contrasty than what the Canon Lin does. However, I will say that if you look like
5:36
at this knot here, in terms of the microcontrast, I do think that the Canon lens, it does have slightly superior optics
5:45
There's just a little bit more of the fine details that are rendered there, but it is very, very close
5:51
Here at the edge of the frame, kind of a similar truth. The Canon shows just the slightest edge
5:57
but it is a pretty close run thing. Looking at the right side of the frame, you know
6:03
we've got a similar story here. I still do think that the Canon is delivering a slightly better
6:10
performance but it's not a very big margin anymore. All right now if we throw the
6:15
Sigma into the mix once again it's exposed at one one hundredth compared to
6:18
one 25th for the Canon and the Tamron lenses. Looking at the center of the
6:24
frame here you know the the at F4 the the Canon has obviously tightened up a bit
6:30
more because if anything the gap has widened a little bit here in terms of the
6:35
resolution from the Sigma and so the Sigma is definitely not as good as the Tamron and then definitely not as good as what the Canon is
6:45
And once again, its corner performance is still not fantastic. The gap is kind of widened there with the cannon on the right versus the Sigma
6:55
And so once again we've got a similar kind of story here that the best lens here is the Canon
7:02
However, now the Tamron is incredibly close. So what happens if we go on down to F5.6
7:10
You know, I think it's pretty much the same story as at F4 for the Tamron
7:15
Both of them look very, very similar, but if I'm going to give an edge to any lens
7:20
it's going to be in that fine detail rendering. It's going to be to the Canon, which really does deliver an exceptional performance there
7:29
At the edge of the frame now, you know, it's close, but the slight edge still goes to the Canon lens
7:36
And so once again, we'll just break down our winners at 24 millimeters
7:42
It is Canon, followed closely by the Tamron, particularly when stopped down
7:47
And then kind of a distant runner-up is the Sigma, which looks pretty good in the center, wide open
7:53
but is really outclassed at the edges of the frame. So now we're going to jump ahead to 50 millimeters in the focal range
8:00
And so looking at these two images globally, once again, let's take a look at the focus breathing situation
8:06
on the Tamron, and so if we look at the right side, the Tamron is actually framing a hair tighter here
8:13
than what the Canon lens is, and then if we look over to the left side
8:19
the Tamron is also framing tighter on this side, and so if there's any focus breathing taking place here
8:27
it's actually by the Canon and not by the Tamron, and so that's a positive for those concerned
8:32
about something like that with the Tamron. Now, center of the frame's sharpness here at 50 millimeters
8:38
Once again, the resolution is actually pretty much identical. The contrast, however, does favor the Canon lens at the edge of the frame
8:47
I've noted, as have other shooters, if you end up buying the Tamron 24 to 70, a G2 lens
8:53
all you've got to do is really stop down to F3.2 and that contrast jumps way up
8:59
So just a little tip if you want to maximize your lens shoot at F3.2 instead of F2.8 if you want that extra contrast
9:08
Edge of the frame, pretty much a similar story. Resolution is actually quite similar
9:12
but there is a little bit more contrast for the Canon lens
9:16
On the right side of the frame, at least in this copy, the Canon is actually the stronger on the right side
9:22
And so it a little bit wider a gap although again not by a whole lot on the right side Now when I tested the Sigma lens it actually was the strongest performance its strongest performance was at 50 millimeters And so as far as focus breathing
9:37
also not an issue on the Sigma, it's framing tighter on this side
9:42
and it is framing tighter on the other side as well. And so at 50 millimeters
9:47
you're getting a tighter framing by the third party lenses than you are by the first party
9:51
So those that like to start rumors to not substantiate them, take that
9:55
Anyway, as far as sharpness goes, center sharpness, the cannon has the edge here
10:02
You can see that superior microcontrast at F2.8. Out at the edge of the frame, however, the sigma I think is pretty much every bit as good in both contrast and resolution
10:15
This is where it is strongest, most even consistently across the frame
10:19
And look here on the right side, this is where the Tamron didn't show so well
10:24
The Sigma actually shows really well on this right side at 50 millimeters F2.8
10:29
And so in terms of center sharpness, the cannon has the slight edge
10:34
The Sigma actually has the better edge performance, wide open F2.8. The Tamron, of course, is very close to both of them
10:43
Stopping down to F4, and here we're going to see for the first time that at least at 50
10:50
millimeters we have found that the tamron actually requires even less exposure than what the cannon does
10:56
and definitely than what the sigma does. And so the superior light transmission of the very new
11:02
Tamron lens shows up here. It requires less light than these others. Now once again, we see a huge
11:08
uptick in sharpness and particularly though in contrast with the Tamron lens that now has every
11:15
bit as much contrast as the cannon and looks pretty fantastic here in the center of the
11:20
frame. Very similar performance and if anything I would give a slight edge to the Tamron in terms of the
11:27
overall pop of the image there. Looking out at the left side, I would say that, you know, there's some
11:35
give and take there. There's areas where I like the look like on this board. I like the look of the
11:39
cannon a little bit better around this knot area. The Tamron is every bit as good and over to here
11:45
So it's kind of a draw towards edge of the frame. And here on the right
11:50
right side. If anything, I think I like the Tamron, you know, the resolution throughout this area
11:57
it's definitely beaten out the cannon. And so stop down, the Tamron actually becomes the better
12:02
lens at F4. Now, stopping down the Sigma to F4, I want you to know one thing, it's exposing at
12:09
150th of the second, whereas the Tamron is exposing at one one hundredth of a second there at F4
12:17
The Canon is at 160th. And so the Tamron is definitely. has better light transmission here
12:23
And so looking at the center of the frame, this is also a strong performance by Sigma
12:29
with both of them looking roughly the same out on the left side of the frame
12:35
I think that there may be just, again, it's a tiny hair more for the cannon
12:41
but if we move just that one board extra towards the center, I think that the Sigma looks a little bit better
12:48
out on the extreme right side, the Sigma looks a bit better than what the cannon does. So stop down both of them to F4. Note the difference in the exposure. You know, the shutter speed required to get similar exposure. But look here in the center of the frame. Tamron has just a little bit more pop than the Sigma does, although they're both extremely, extremely close. I just like the F4 contrast a bit better on the Tamron. On the left side of the frame, you know, I would say here
13:20
the Sigma maybe has the slightest, slightest edge and then looking at the right side of the frame
13:28
I'm gonna say the same thing, Sigma has a slight edge there
13:32
And so, you know, 50 millimeters is a little bit more of a toss-up
13:36
All of them have different kinds of winds here. And so don't buy it for 50 millimeter sharpness
13:42
There's not enough difference there to be worthwhile. Now, jumping to 70 millimeters, let's check on our framing here
13:50
Again, Tamron on the left and Canon on the right. Exposure values have equalized here, both them at 1 25th of a second
13:59
As far as our framing goes, the Tamron is the slightest hair wider at this point here
14:07
but over on this side it is framing basically just as tightly And so the cannon here has a hair breath but it not enough to be it not even a millimeter difference
14:22
It's not enough to really be a consideration. So focus breathing is essentially a non-issue
14:29
Now sharpness, however, is a different story. Center frame wide open F2.8, 70 millimeters
14:36
The cannon is going away winning here. Better contrast, better resolution. That's an easy win there for Canon
14:44
Out on the edge of the frame, however, you know, the Tamron delivers great evenness
14:48
That's a real strength that I've seen. And here on the edge of the frame, it is, other than I think there is a tiny, tiny bit like here, of more contrast for the Canon
14:58
But it's too close, really, to call. They're virtually equal on the left side
15:04
On the right side, I think there's a bit more contrast for the Tamron, or excuse me, the Canon at F2.8
15:10
As far as the center, it's a better center performance than what we saw on the Tamron in terms of the contrast and the resolution
15:18
I do think that I very, very slightly favor the canon, but it is within the margin of error for field use for sure
15:28
Out on the left side of the frame, once again, pretty much the same story
15:33
They're more similar than they are different. Potentially a very slight edge for the cannon, but on the right side of the frame
15:40
the frame, I would say, you know, they're very close with the Sigma maybe having the slightest
15:46
edge. So once again, we're seeing some give and take there. All right, now at F4, both the Canon and
15:53
the Tamron are exposing similarly. And so looking at the center of the frame, you know, once again
15:59
the Tamron takes a big leap forward in terms of center sharpness. However, I'm just seeing
16:06
where I, just a few places where I see just a little bit of an edge in terms of
16:10
of resolution and contrast for the cannon. So while it's much, much closer, I'm going to call it
16:16
still a win for the cannon in the center. On the edge of the frame here, however, looks like
16:22
the Tamron is every bit as good. And so, you know, that advantage is lost by the time you get
16:31
out to the edge of the frame. On this right side here, you know, they're fairly close towards
16:36
this edge. But, you know, if you look at this area here, the Tamron is actually a hair
16:40
better. And so once again, just stopping down the Tamron just even a little bit really
16:46
bumps up its contrast and its overall performance. Now comparing the Sigma, once again
16:51
a little bit more shutter speed there, 150th instead of 160th to equalize results. Here we're
16:58
seeing that the the TAM, excuse me, the Sigma is giving a pretty similar performance to
17:04
that which we saw from the Tamron. It is close, but the edge goes to the cannon there in the
17:10
center of the frame. On the left side of the frame, however, you know, the sigma sharpness
17:15
it doesn't quite reach the edges as well as what either the cannon or the Tamron does. And so
17:21
here we're seeing an edge for the cannon on that side there. And on this side, they're about
17:28
similar, the slightest edge for the sigma right in that spot there. And so once again to wrap that
17:34
up center sharpness wide open. It's definitely the cannon and wide open center sharpness
17:42
The sigma is in second place. However, it's in third place at the edges. Stop down to F4. The Tamron is
17:50
as good basically as the cannon and the sigma is a little bit behind, particularly at the edges
17:56
Now for the sake of length, I'm going to cut it off there and we're going to pick up in
18:00
part two. And we're going in part two, we're going to look at infinity focus, but we're
18:04
We're also going to look at an interesting twist. And what happens with these results if you switch from going to a very controlled, stabilized
18:14
tripod result that obviously favors pure optics, and you go to a more real-world hand-holding
18:22
type result in the way that a lot of these lenses are going to be used
18:26
That's going to produce some interesting effects when we look at that. And so stay tuned for the second part of this head-to-head-to-head series
18:34
and I'll be coming back to you with it very shortly. I'm Dustin Abbott, and if you look in the description down below
