Lots of nice photos in this thread.  Do any of you know (first hand or otherwise) whether this lens has suffered from the AF inconsistency problems that people complain about re some of Sigma's primes?

I use this lens on my 7D to shoot my very active daughter (see the many pics in this thread) and have no complaints on it's AF accuracy.

I have to say I really liked the lens overall, but I also had some AF issues on my 7D II. That is also why I didn't buy it after the test period.

Still can't see the need to "upgrade" from my "ancient" 7D. This lens kills it every time.

Some harsh summer light with the terrible 7D, and this lens still performs.

Just started my review of this lens.  IQ looks nice, but on the wide end I had to max out AFMA (+20) to calibrate it.  It was so bad that the automatic function of FoCal couldn't calibrate it.

The funny thing is that with tele end was basically dead on and needed no calibration.  Never seen that with any lens before.

Wow that's odd. I shoot this lens on a 7D in Ai Servo mode at both ends, never adjusted a thing and get in focus shots easily over 90% of the time.

The AF inconsistency issues will continue to hold Sigma back. This is also why I switched from the Sigma 35 Art to the Canon 35 2 IS.
