So I had a shoot last night, my 1st AC mounts the lens (a Cooke 20-100 zoom) normally in the PL mount, at least he says so.
We try to swap it out for a prime and we can't actually twist the lens mount! We had to transport the camera home with the lens still attached.
Any recommendations? Advice? Ideas? I'd like to break down my camera rig before long ...:umm:
