Sigma 35mm 1.4 Art Canon Focus Issues. 35mm f/1.4 lenses tend to be low in/void of ca (chromatic aberration) and the sigma 35mm f/1.4 dg hsm art lens performs well in this regard. Actually, almost if not identical, with the same work around we reported before the official fix.
An an owner of the sigma 50 f1.4 no art and the sigma 35 f1.4 art, i can perhaps shed some light on this by sharing my experience. Broke twice off the mount and constant focus issues, i know it is extra money but get yourself a 35 for whoever makes your body.

But it seems once again canon and sigma just aren’t playing nice together. But this is still a darn nice lens that produces outstanding images.
