Does anyone know what the differences are between the two Voightlander/M Bayonet Adaptors? One is for 50/75mm lens and the other is for 28/90mm lens. I guess my query comes from not being able to discern any visable difference between the two.....thanks and cheers! Sam

There's no difference if you use them on Cosina-Voigtlander bodies, but on a Leica, they bring up the right framelines for the focal lengths marked on the adapter, so you buy the one for your lens you intend to use with it, so you get the right frames in your Leica.
The framelines are actuated by one of the bayonet lugs on the back of the adapter (or the back of a lens with an M-Mount). One of the four lugs varies in length depending on the framelines the lens is intended to trigger, and a sensor cam inside the camera body senses the length of this part of the lens mount to bring up the right framelines.

Thanks a lot Chris!! Head scratching solved ..... I use the Bessa R2A & R3A as my bodies du jour, so I assume that my 50 and my 85 Russian Jupiters can go on either adaptor. My 35 Nokton is a bayonet anyway so no probs there. Thanks again. Cheers, Sam
