    Works perfectly. My Sigma EF mount lenses focus much faster than they did on my Rebel T6i. No wiggles or looseness at all.

    Mine broke within a couple of months of use. The metal part that holds the lens in bent. It still works but my lens doesn't fully click in which makes me nervous with bigger lenses.
