I see AF (backfocus) issues in some reviews, are these false or not ?
Any figures about how much % of the lenses would affect this ?
Normally quality control would be strict for the Arts as it's a more expensive class.
I didn't have any problems with my 35 Art & 50 Art
It's because I got a nice bid on my 85L (MKI) for the same price of a new Sigma 85 Art.
The 85L doesn't pass any distance info to the body, I don't know in which way this can affect pictures without & with flash (wireless setup).
