This sale is for a really excellent condition Mamiya RB/RZ67 100-200mm Lens Holder for supporting the zoom lens on the camera, reducing the strain on the bellows / focusing rack on the camera body. It is in perfect working order, but the riser bars for use with a RZ67 winder are missing. There are only normal very minor signs of use, just the usual small paint chips along the edges.
Use this Mamiya RB/RZ67 lens holder to protect your camera from the weight of the lens. It is intended for use with the fairly heavy zoom lens, but can also be used with other long lenses such as the 250mm or 360mm. This lens holder can be used with both the RB67 and RZ67 cameras, although you cannot use it with a RZ67 with power winder attached; the riser bars are needed for the RZ if you are using a power winder.
