This sale is for a really excellent condition Mamiya RB67 ProSD 120 6x7cm back suitable for use on any RB67 Pro, ProS or Pro SD camera.
This back is in really excellent condition. It has only normal very minor signs of use, but the rear plate on the rear of the back (with the film box lid slot) can slide out. This is not a real problem and a spot of glue would stick it in place if it bothered you. Price reduced because of this. This works perfectly, fully tested. You get 10 6x7cm frames on one roll of 120 film.
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!
