Mamiya 35mm back for 645 Super and Pro format_Instax Wide this ring complements the BR-2This Mamiya back lets you shoot plain old 35mm film in your Mamiya 645 Super or Pro camera. Yes, there's a crop effect (this is the APS C to 6x4. 5's "full frame") but you get 36 frames instead of 16, and it looks just like the normal 120 back, so your reputation as a big shot medium format shooter will remain intact. In excellent condition. Viewfinder mask is not included.
