The Mamiya RZ67 was an electronic "upgrade" version following the previous RB67 series of cameras. It refined some features of that camera, such as coupling film advance to the main lever of the camera, so that one no longer had to worry about forgetting to advance film and inadvertently double exposing.
The camera also became battery dependent, which brought both pros and cons. The biggest benefit to this change comes if you pair the camera with the AE Prism. This combination allows the RZ67 to operate in aperture-priority auto exposure, or in a metered manual mode. The electronically-controlled leaf shutters for the RZ system also have an extended range of shutter speeds, going as long as 8 seconds, while topping out at 1/400. The RZ67, like the RB67, makes a great studio camera. It shines on a tripod due to its size. It makes nice, large 6x7cm negatives and uses excellent Mamiya lenses to make these images. Speaking of lenses, the RZ67 can even be used with the older RB67 lenses. But don't expect your RZ lenses to be backwards compatible.
There are a couple different iterations of the RZ67 camera:
RZ67 Pro II - Fine focus control knob added to right side of camera. Shutter speeds can be set in 1/2 stop increments. Improved focusing screen with LED indicators for various camera states. Slightly improved film back with extra frame counter window to make it easier to see regardless of back orientation.
RZ67 Pro IID - Integrated interface for accepting digital backs. Some minor internal mechanical improvements to the camera.
Mamiya RZ67
There are several distinct advantages to the Mamiya RZ67.
One of our favorite features is its extended focusing rack, which allows super short minimum focusing distances with any lens you put on the camera. Even with the standard focal length, the camera is capable of focusing at a minimum distance that is roughly equal to the length of the camera itself.
Splendid!
Just wait til you put something like the 50mm on there and see how close that lens can focus...
