Pro

  • Magnifying “chimney” hood – better light sealing and high magnification than waist level finder. The chimney finders look directly down on the screen, they do not contain a pentaprism. Hence, they keep the left/right reversal of using the waist level finder.
  • Dual magnifying “chimney” hood – similar to the above but magnifies the center view between 3x and 5x.
  • CdS “chimney” – built in CdS meter with TTL metering. This is a bit strange of a meter, you actually move a little sensor around the view finder, giving you a spot meter. Note, this meter is not tied to the camera in any way, you have to move the settings read from the meter to the camera, there is no connection. This meter only features a on/off switch, so if you forget to turn it off, the batteries will drain.
  • CdS prism finder – A bit simpler than the chimney CdS meter. This is an averaging meter and it is a prism, so it corrects the left/right reversal. It only features an on/off switch, so the batteries can be drained.

Prism Magnifier FD701

A little magnifier optic that flips over the PD Prism and Prism Model 2.

Dual cable release

Due to the somewhat tricky nature of using a cable release on the RB67, Mamiya sold a dual cable release. It is a single plunger with two connectors, one is connected to the normal shutter release on the body, the other to the shutter release socket on the lens. As you press down on the plunger, the cable connected to the body triggers first triggering the mirror up, the cable connected to the shutter release on the lens is triggered, which activates the shutter.
