I have tried for some time now and cannot figure this out:
I have put an adapter on my gfx 50s for Nikon.
The lens is a manual focus 135mm zeiss apo sonnar.
I get the lens on and it seems to be very good, but
I can not take a picture. The little display at the top of the camera says
f.0 no matter how I turn the apperture ring. The screen on the back seems
to understand that the apperture is changed because the live view is changing.
Anybody have any idea what I do wrong?
