Does anybody else have issues with recessed boards and cable releases? I seem to recall some highly flexible release adapters and also a 90 degree angle adapter available somewhere (Calumet?). Can anyone point me in the right direction? I have no choice but to use a recessed board on my old Calumet monorail when I mount my 90/8 Super Angulon. The bellows just won't compress enough to get infinity focus.
