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!
I would have wished you luck had you got the Sigma given the AF performance can be a bit troublesome. With the 24-70 II you shouldn't need luck, it is the as close to a perfect lens you can have in this FL range.
There are quite a few users that would disagree with you
I'm sure there will be a few. TBF, I did choose my words carefully ... no?
In fact my comment was about the perfection of the 24-70 II
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.
