Hey guys..... looking for your highly valued opinions. I've been considering a Canon 24-70 2.8 to go along with my 7D Mark ll. I've mentioned this before and the problem I related earlier was the lack on IS. I've been reading and talking to people about the Sigma 24-70 2.8 ART with OS (optical stabilization) and I'm impressed by what I see. At $450 less than the Canon and with OS it sounds like a very viable option.
Let me know what you guys think.
Thanks, Danny
First of all, I have the Canon 24-70/2.8L personally and it's an excellent lens. And I actually like it better for portraiture on an APS-C camera such as my 7DIIs, than I do on full frame (where it seems a little "short" for portraits, though I know many people use it that way).
IS is the least of my concerns, with this range of focal lengths... especially with a zoom that goes to f/2.8 and cameras that can easily do good quality images at ISO 6400, maybe even higher depending upon the intended use of the images.
HOWEVER, it's big, heavy and expensive. The Canon 24-70/2.8 "II" requires 82mm filters. (So do the Tamron and the Sigma... the Tammy weighs about the same as the Canon... the Sigma is 25% heavier still.)
Unless I need the flexibility of the zoom, I often just carry some smaller, lighter primes such as 28/1.8, 50/1.4, 85/1.8. I also use the Tamron 60mm f/2 Macro/Portrait (crop only & slower focus, but fine for macro & portraits). The 35/2 is on my short list, too. All these are one to two stops faster than the zoom and I can buy about three primes for the price of one EF 24-70mm!
If I were setting up a full frame, landscape kit personally I'd get the EF 24-70mm f/4L IS USM... for it's smaller size, lower price, excellent edge-to-edge sharpness and unusually high 0.7X magnification capabilities (no need to carry a macro lens, too). It uses smaller, more reasonably priced 77mm filters, too. And, yes, it's got IS, though for a lens like this that's a pretty low priority consideration. (Note: I love IS on
telephotos... have been using some with it for fifteen years and swear by it. While nice to have on them, I just don't consider IS a very high priority on lenses shorter than - say - 85, 90, 100mm.)
But for use on and APS-C 7DII, the EF-S 17-55mm f/2.8 IS USM might be a better choice... Sure, it's not an "L". But it's smaller, lighter, much less expensive... and equally high image quality/focus performance... and it has IS (and 17-55mm really is not all that different a range from 24-70mm).
Yes, third party lenses are definitely an option worth considering, and might be a good value. But there's always a risk with those, that they may or may not work properly with a future camera upgrade.
