Question about Sigma 50mm f/1.4 DG HSM ART, Canon EF
how well does the af work on the 5d mark 4? are there any problems? does anyone have any experience with it?
No, there are no problems. The AF motor works very fast, not quite at Canon L level, but in practice I never had any problems. It is very precise and never pumps, which is a big plus when filming!
