We’re told that Sigma is aiming to announce a 24-70mm f/2.8 OS Art series lens ahead of CP+ in Yokohama, Japan, which starts on February 23, 2017.</p>
<p>We’ve seen one patent for a new Sigma 24-70 f/2.8 <a href="http://www.canonrumors.com/patent-sigma-24-70mm-f2-8-dg-os-hsm-art/">back in March of 2016</a>.</p>
<p>We’re also told that Sigma hopes to have the lens at retailers before the summer and that the announcement could be pushed until after CP+ if they can’t meet that target.</p>

Canon engineers are furiously updating firmware so that this lens won't AF properly on Canon bodies... ::)

They won't need to. Not because of Sigma's error, but every Canon camera focuses differently, and has a database in the camera to tweak it for each Canon lens on that camera. Third party lenses have a uphill battle to get there lenses focusing well on Canon cameras, they tell the camera that they are a Canon lens, but they do not act the same as a Canon lens on each and every camera, so some camera - lens combinations will work better than others.

They will probably set it up to do as best it can on a 5D MK IV but owners of other Canon models may not get the peak performance. It might even struggle on the 5D MK III since it has a different AF system.

Those who are able to use DPAF will see very accurate AF performance, since the camera uses contrast detect as a final step to get very accurate focus. Speed may suffer, but accuracy will be excellent.

I might well have been interested before I switched from full-frame to crop. One of the reasons I did is because the Canon 24-70/2.8 II doesn't have IS so it has limited advantages over the far-cheaper Sigma 18-35/1.8, and the rest of the full-frame system has disadvantages for me (no practical hyperzooms, no light-weight video-friendly telephotos, no built-in flashes, no reasonably-sized body with 10fps, low pixel density except for the slow 5Ds).

But now that I've made the switch, I can't see switching back any time soon, so too late Sigma.

I do not anticipate any reason to move off my EF 24-70 II, which is ridiculously good.

But, I do like to see new stuff. I love my 50A and 150-600S. I am very impressed by the reviews I have seen of the 85A. So, impress and entertain me Sigma, but just don't count on getting my money this time around.

More quality lenses no matter whom they are manufactured by is a good thing. I like, occasionally love certain Art series lenses but since I own the Canon Mk2 of this zoom, it won't be for me. But man, I really loved the Sigma 24-35 while I had it and I think that they really have the AF dialed in for shorter zoom spreads now.

It would be cheaper than current Canon counter-part. And I doubt it to be less of a quality than it.

However my main concerns are regarding AF speeds. My bet is that Canon ones will be always hard to match again just like the 70-200 IS 2.8 II.
Not to mentioned the 24-70 2.8 IS which is rated as CR2 already. I think that the most general lense (especially well utilised from it biggest market - the wedding colleagues) it is an essential feature.

But again for most of the rest who are not concerned with AF speed the Sigma ART would be a better choice. That is at the better price offer, of course. :-)

This Sigma announcement however is good. Maybe it would make Canon hurry up with street release date for that awaited IS 2.8 beauty. :-)

So you are speaking for yourself and the many other photographers who don't care if subjects are in focus? Sigma certainly has tapped a market.

This might be great news for those of us that shoot both Canon 6D/7DII and Sony A7II. With a Canon mount I can use the Sigma MC-11 to mount on my Sony. I use my Canon L glass and it works great with the MC-11 on the Sony and AF is pretty fast. Expect this new lens will work just as well.

Don't quite get you? What made you believe I don't care about the focus?

When it comes to Sigma, "AF speed" is a euphemism for "AF sometimes."

As I already said speed is not good. But the 50 mm ART is nat that slow but quite good on getting most images sharp.

As for first zoom ART lense we are about to see your theory. However please do not missinterpred anymore my words in future.

Thank you in advance. :)

Ah, there it is. I was wondering where you were headed with that. I welcome others' thoughts on this.

To me, Sigma appears to be turning a corner with AF:


  • The 35 f/1.4 Art (aka 'the 35L II minus the 35L II's AF') would inconsistently swing and miss in non-dock-correctable ways. That's a non-starter for me.

  • The 50 f/1.4 Art would inconsistently swing and miss in non-dock-correctable ways. Ditto: Non-starter.

  • The 85 f/1.4 Art appears to be a new animal, and AF testing of that lens has shown much stronger performance. If I was into portraiture (scripted, lit portraits are simply not my bag), I'd strongly consider one over the 85L.

  • Recent non f/1.4 Sigma lenses naturally have fared better in comparison to their wide aperture brethren. If I needed one, I'd snap up a 150-600 or 12-24 f/4 from Sigma without much concern.

I doubt Sigma will ever have the same AF speed / reliability as a contemporary Canon USM lens, but the idea that you'll miss a quarter of your wide open shots should no longer be a pain point in opting in for the newest Sigma lenses. With the 35 and 50 Art, people complained, Sigma listened, and apparently they've made positive changes.
