I never had an issue with the lens and it's focus on 5DII, if anything when focusing very close it seems to not be spot on sometimes, but I blame that on super narrow DOF + focus and recomposing, and this is the only lens I didn't have a need to AFMA. This shot below may not be perfect (F/1.4 anyways) but I put the camera up to my face, and took my first shot, and a winning photo popped out!
I also have done a lot of street candids shooting from hip, I've gotten quite a lot of tack sharp faces of passer-byers, and not to mention how sharp the lens is overall.

Definitely check your AFMA before you go any further.  Here's an easy guide:

I'd get FoCal or a LensAlign instead.  I find the moirĂ© pattern approach has too much 'slop' (camera can be moved quite a bit with no discernible change in the moirĂ©).

I have the sigma 35. focusses like a dream straight out the box. Servo performance is good and no AFMA needed on my 5d3.

I tested both the canon 35L and sigma 35 before purchasing and found the canon to be faster on AF but softer @ f1.4.

My siggy 35 even rocks on my 5DII's "ancient" AF system. I was actually using it in servo the other day while catching clear bubbles floating through a bright blue sky. Not necessarily high speed action, but still tricky for such an "inferior" AF system nonetheless.

Nicely done.  That is a strong image - subtle and beautiful!

To the OP...isn't the new Sigma 35mm f/1.4 the one that can be configured via a computer without having to send the lens to Sigma?  I thought it had the ability to adjust front / back focusing issues until you get it correct. 

As others have also said, there is the MFA available on the 5D III itself.  One or the other should fix it, but I'd prefer to fix it on the lens. 

Kind regards,
Jason
