Make sure you test by taking a shot and not just focusing.
Today though I put my 50L on it and headed for a walk on my A7RII. Focused and took the first image and all went great. It was when I tried to take the second image that all went sideways. It was completely over exposed. With a puzzled look I wonder what I did wrong. Tried again. Some results.
Same thing happens with my Canon EF 24-105/4L IS with the MC-11 adapter on my A6300. The images are being made with a considerably slower shutter speed that results in the over exposure. However, the AF (AF-S) with that lens on my old Commlite adapter works much better on the A6300 than it did on my A6000 and no over exposures.
My Canon 70-200/4L IS, 35/2 IS, 40/2.8 STM, 100/2.8L IS, and Sigma 150-600 C don\'t exhibit any over exposure errors with the MC-11 and AF-S works.
My EF 300/4L IS doesn\'t AF with either adapter but aperture control and IS works. My EF-S 24/2.8 doesn\'t fit on the MC-11, but it does fit on teh Commlite and AF-S works well enough.
