I had saved money for the Sigma 35f/1.4 A, but my tax return was higher than I expected, so I just ordered the Canon 24-70f/2.8 II instead!!! Wish me luck!

It is my most used lens and the performance is outstanding. I don't think I have a single bad images I can blame the lens for (I have lots of them though
). Have fun!

There are some people who have problems with the 35A, but on a scale perspective, probably not more than those who had problems of various nature with the Canon (coating peeling off, zoom clicking sound, copy-to-copy inconsistency etc..).
My Sigma had backfocusing problems only at medium distances (5-10m). In close and infinity focus it was spot-on out of the box. It's the reason why the USB dock is great: it lets you AFMA at different distances. At the moment I'm strugling a bit with the Canon 24-70 f/4 L: it seems to have a similar problem and I wasn't able to correct it yet because at some distances it works great, at other distances it doesn't, and there is no single value that can fit all situations. I need to spend quite some time on FoCal to find the best compromise.

Haha ... I thought so too but only later and didn't bother editing my post ;D
The point though is that you usually suffer "bad luck" if you get a bad Canon lens - a very high percentage of Canon lenses work find right out of the box, but you need "good luck" to get a Sigma lens that works great right out of the box.
Sigma is improving but given that they have to reverse engineer the Canon AF to get their lenses to work on EOS bodies, the AF feels a bit of a let down compared to the Canon lenses.
Additionally, from personal experience, I've found that if a Canon lens does not work properly on a Canon body, I can send both to Canon for calibration. With a third party lens, Canon refuses saying it's the third party problem while the third party blames Canon. So basically, I feel safer with Canon gear

When the Sigma 35 Art is well focused, the IQ is very good. But the AF is not consistent. When I got it last summer and the days were long and light was good and I normally used f5.6 or thereabout, it was excellent. In November days are shorter, light dimmer and f-stops wider and I got more and more out of focus images. I did a new AFMA (Focal) and focus had drifted 7 points. Whether that was a one-off or something that I can expect to happen again is yet to be seen.
My Canon 24-70 f2.8L II has been outstanding from day 1. I have not had any of the problems other report. Like some other posters here, I am also a bit reluctant to buy non-Canon lenses, due to reverse engineered AF solutions. Sigma does seem to have something going though.

To my mind, you can't have a FF Canon without a 28-70.... It seems like the perfect lens, closely followed by a 70-200..

I have both lenses. They are nice company to each other on 5dmk3, that 1.4 matters a lot when there's not enough light. My 24-70mk2 doesn't show any clicking problems and IQ is on par with any prime lens, from corner to corner. Sigma needed +5 AFMA and still exhibits slight front focus issues at mid distances (2m to 5m) while L zoom needed -2 AFMA at wide range and +1 at longer range. Don't know why but sigma's coating seem more pleasing to my eye. You'll love your 24-70!

Kudos. I'm not that big of a fan of the focal length... so I'm staying with my 24-105 until the reviews for the sigma 24-70 f/2 come out... provided the lens ever comes out.
At that point... I'll make my choice... but who knows maybe canon will finally release their 24-70 f/2.8L IS...
