This sale is for a genuinely mint condition Mamiya RB67 ProSD 120 6x7cm back suitable for use on any RB67 Pro, ProS or Pro SD camera.
This back is in mint condition. It has absolutely minimal signs of use; it was previously used for taking images from an electron microscope (really!) and had never been mounted on a camera until I tested it. It is not new, but it has barely been used at all. There are only a few very faint marks and no wear at all.
The big thing about this back compared to the usual ProS back is that you do not have to worry about rotting light seals – this back does not use or need them.
Not so easy to find now as every RB user wants these backs – grab it quick before someone else does! You will not find a better example unless you come across a brand new back.
