welps, sure enough, it's junk, .50 is unusable.
sigma 50, can no longer AF
EF 100, all over the place with AF. It does detect the eye, lockon AF enabled, but it wont lock and loses it.
if you mount with the button, then it reverts it to current day metabones, however, I dont want to mount it that way every time I uses it, so back to .46. I'm glad that MB is headed that direction
