Mamiya Winder Model 2 RZ
An extremely important accessory for almost all professional applications. The Winder RZ frees the photographer from the need to manually activate the film advance/shutter cocking mechanism. This lets the photographer concentrate fully on the subject, while the winder takes care of the film, shutter and mirror settings. Single-frame or sequential film advance (1.5 sec/per frame).
The Winder RZ Model II is powered by six "AA" type batteries (alkaline or NiCad) and will give about 300 - 500 consecutive shots. Weight 19.4 oz. (550g.) without batteries
