As the name of the camera “RB67” already suggests, the picture format is
6x7cm. Recorded on 120 film, which is still available today.
Good to know, the mystic scale
Unlike other cameras, The Rb67 Pro s is not focused directly on the lens, but with the help of a bellows.
Only the aperture and shutter speed, flash and mirror lockup, are set on the lenses.
Due to the fact that a bellows is used for focusing, the way of the light, from the lens to the film, is getting longer and the exposure times must be adjusted accordingly. This is done with the help of the “mystic” scale on the side of the
Mamiya RB67 which becomes visible when the bellows are extended.
Please transport the film by hand
After taking a picture, it is not only necessary to re-load the shutter, but also to manually advance the film.
This task is not happening when re-loading the shutter, like on newer Hasselblads but has to be done by hand. Unless you have a magazine from the first series and want to create a double exposure. Then you can safely leave the lever untouched.
If you have a newer magazine, but still would like to make multiple exposures, after re-loading the shutter, press the small metal burl right above, on the side of the magazine and you are able to releases the shutter.
The thing with the old magazines
Anyone purchasing a Mamiya RB67 will often encounter the problem that the seals of the old magazines are in bad conditions.
This inevitably leads to the incidence of light in the magazine (light leaks), which can be seen as an ugly stripe on the negative. Here it usually helps to renew the seals by a repair service or to replace them yourself. Here you can order a pack of new light seals. Advertisement
