|The lens arrived today. I recently obtained an ETR to Nikon F adapter, in line with most of my other lenses for Sony A7r3.
Unless someone has come up with a way, other than by operating the DOF preview slider, I will have to hold that with my finger.
The particular question is the function, via this adapter, of the cam at about 10 o'clock in the adapter. Its function seems to be to rotate those two pins anticlockwise, past the two green spots. I'm sure it has a vital function on a Bronica camera but why provide this for an adapter with no moving or electronic parts?
