Hi I have the commlite on my sony canon a7s for optical ring, the problem is that diafragama control only works in video mode, photo mode is that the iris at its maximum aperture, someone happened to him?
I've been using the Commlite adapter with my a7s for about 5 months now. Up until a couple of days ago I would have said, "it's fine, save your money" But after the lens lost contact with the camera out in the field, I took off the lens and found that two of the screws were halfway out. It was literally falling apart and if I didn't notice it when I did, I probably be out of a lens right now.
I've had problems with Metabones but they never fell apart on me.
