Has anyone experienced some focus hunting issues when adapting Canon lenses onto Sony bodies? I recently got a Sony A7 III, and the performance so far has been pretty impressive, especially considering the adapted lenses. However, occasionally the lens will just go completely berserk when focusing. It acts kind of like a Canon lens on a Canon camera when it can't achieve focus and you have "Lens drive when AF impossible" set to "on." The focus racks way out, to the point where you have to grab the focus ring and twist it just to get the lens back to some kind of reasonable focus. At first I thought this was just the camera struggling in low light, but it's done it a few times in decent lighting. If I could just iron out this bug, I think this camera would really be viable to use with Canon glass, and I have to admit that it's got some very solid features. Hoping that Canon can come out with something that has all this technology and a menu system that isn't garbage. :
For reference, I'm using a Canon 50mm 1.2L and a Sigma MC-11 at the latest firmware on the Sony A7 III. I'm going to try a Metabones adapter as well to see if that's any better, as admittedly the Sigma adapter says straight up that it's only meant for use with Sigma lenses.
