The more I think about it the more I think I will buy the 24-70 Art. Just not to fond of the 24-105 performance.

Just noticing that the new Sigma has an inner focus design so the lens doesn't extend while zooming, as opposed to the 24-70 2.8 ii

The official page here https://www.sigmaphoto​.com/24-70mm-f28-dg-os-hsm-a (external link)

reports IF design "this lens moves the inner focus groups without changing the lens' physical length"

You are confusing inner focus with zooming. They are not the same.

I had the Tamron 24-70 2.8 VC and I found the IQ & OS great!!! Almost the same like the 24-70 II but with VC.
Eventually I sold it as I couldn't get used to the backward zooming, this would be made like this for filmmakers.

The Sigma 24-70 OS Art has no price available yet, but It will definitely be expensive.
I'd rather keep my Canon 24-70 2.8L MKI, a standardzoom is just for casual (boring) maistream work, so not woth all that money  :p
And if you shoot for customers, they don't notice a tad sharper anyway :)


I really hate to burst your bubble. But the Tamron 24-70 is no where remotely close to performance and IQ of canons 24-70 v2.....not on this planet nor anywhere else in this universe

We tested 6 copies against my Canon 24-70V1 and a 24-70V2 and the tammys were not as good as the canon V1.....against the V2....it could not hold a candle to it in terms of sharpness and IQ...........zoom in to 100% and the file was a distant 2nd to both canon 24-70's and especially to the V2 lens from Canon

The VC copy I had when I owned the II was pretty darn close.

For those who shoot Canon or Nikon & are currently wanting to get a 24-70. See comparison for the current contenders.

IS is important to video, far more important than it is to still, and more important than minor increases in IQ that won't be visible in the moving image anyway. If the Sigma lens matches the Canon model I and then adds OS, it will be more important for video than the Canon model II lens.

The tamron vc sat between then mk1 and mk2 and worked great for video. Too bad it never worked for me on the 5d4 but I fully suspect the art to work great.

I'm willing to bet it matches the mk2 in every department

It won't. Even if it matched it optically (which it won't - quite), it'll never match the AF performance. No third party lens ever has or could match the AF of a genuine Canon.

Depends what your other lenses are. Every review of the Sigma ART lenses I've ever seen has commented that the AF can 'miss' occasionally. For all their optical excellence, it's their biggest single issue.

I used to have a 35 ART and, much as I loved it, the occasional AF miss was irritating. It may only be very rarely that it happens but, if you can't trust it completely, you end up taking multiple shots of things just to be safe, especially at something like a wedding where you can't afford to find your only shot of something is out of focus.

I clearly undertand your point...there is no more irritating issue than an inconsistent AF, it just drives you nuts. I have an hit and miss behaviour from my 135L instead the 35 art is spot on every single shot at 1.4.
There are several reports of Sigma lenses with hit & miss behaviour, though the situation has improved with the Art series, once you get a good copy it shines. For a pro dealing with this issue would be unacceptable.
It seems that the 85mm Art has also improved the AF accuracy on Canon bodies (most of the complains are from Nikon shooters).

BTW my other lenses are in the signature (5 Ls +1 USM)

HAHAHAHAHAHAHAHAHAHAHA​HAHAHAHAHAHAHAHAHAHAHA​HAHAHA

Oh wow that's funny.

This idiot (me) has shot a lot of 3rd party glass... I've also owned all the finest L glass too outside of a few of the super tele.

Thanks I really needed that laugh.

You wouldn't think a 200 F2 and 5d4 would ever miss but mine has missed on some shots that's left me saying wtf

There is multiple stages of AF. I also have had many 3rd party and Canon lenses. As for continuous AF, where the lens just has to track along on a subject, Sigma's HSM is quite good, and is actually better than some of Canon's lenses (for those without true USM, like the 50 1.4, etc).

However, I haven't had a case where a Sigma lens can immediately lock on a target instantly when I pull up the camera and mash the AF on button. The Sigmas lag just a bit before they acquire lock where Canon true USM lenses (like on the 70-200) are nearly instant. That is where I have had to stop using Sigmas, during sporting events, they couldn't keep up with the instant action part of the event. HSM is nice, but it still falls slightly behind Canon's. For any other kind of AF need though, Sigma HSM is quite good and most likely will appear to be equal to Canon's.

when I look at your sig, and see you have a 5DSR, I think this may have something to do with your comment

as a previous 2 body 5DSR owner, now only have one, any longer non IS lens is almost impossible to consistently nail - I sold the 135L because of the 5DSR

in terms of lenses that are amazing on the 5DSR
- 70-200 2.8 II IS, 100-400L II IS , Sigma 24-105 F4 OS, Canon 35F2 IS, Tamron 45/85 18 VC
- Canon 24-70 2.8 II and 35 L II 1.4 are good but need very, very high SS - they are both amazing however on a 5D3 / 1Dx_II

The only two lenses I never ever worry about missing a single shot are the Canon 24-70 F2.8 II and the Canon 70-200 2.8 II IS on a 1DX_II - never missed a single shot at a wedding with either of these on a 1DX_II - a close second is the Sigma 24-105 F4 - it is a great lens shot wide open at F4 at all FL and I have never missed a shot at almost any SS on the 5DSR with that lens.


Hockey and wedding photographer. Favourite camera / lens combos: a 1DX II with a Tamron 45 1.8 VC, an A7Rii with a Canon 24-70F2.8L II, and a 5DSR with a Tamron 85 1.8 VC. Every lens I own I strongly recommend [Canon (35Lii, 100L Macro, 24-70F2.8ii, 70-200F2.8ii, 100-400Lii), Tamron (45 1.8, 85 1.8), Sigma 24-105]. If there are better lenses out there let me know because I haven't found them.
