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.

We’ve seen one patent for a new Sigma 24-70 f/2.8 back in March of 2016.

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.

CR guy:  Your title was only so interesting, but your first post to this thread has OS in it! 

Very cool to see.

About time. To bad for Sigma I do not buy their lenses anymore. This is the lens they should have released instead of the 24-35mm f/2 which was a stupid focal length.

This will be interesting.
I'm a huge Sigma fan, but let's see this lens top Tamrons excellent 24-70/2.8 with stabilisation.

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.

As opposed to my thoughts, no freaking way I am excited. Just one exclamation point makes all the difference!
Too often we lose sight of the fact that photography is about capturing light, if we have the ability to take control of that light then we grow exponentially as photographers. More often than not the image is not about lens speed, sensor size, DR, MP's or AF, it is about the light.

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.

Lost you there.

You have a 24.2MP 80D + Sigma 18-35mm f/1.8 set to 22mm vs 22.3MP 5DmkIII + Canon 35mm f/2. What difference does the pixel density make?

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.
