Mamiya RB67 ProSD 6x4.5cm Back Filter Type_Neutral Density This is the correct insertThis Mamiya RB67 back is set up to shoot 6x4. 5cm images rather than the usual 6x7cm, which means you get more shots per roll and you can switch easily between vertical and horizontal formats, thanks to the RB67's rotating back. This is a later ProSD back, but it will fit any RB67 body. Cosmetic condition is very good, with light finish wear; function is excellent.
