Has anyone mounted non-Mamiya lenses to the RB/RZ? Maybe use a body cap as a lens board? Or, does anyone know which lenses might be compatible to do this and have infinity focus? Having a shutter is not mandatory.
I've chucked a 35mm format 50mm lens on... backwards.. fun macro times. No shutter though, annoying. But in the dark, using off camera flashes its good.
I've done several adaptations using body caps. These include a 50mm macro lens from a 35mm Mamiya ZE, and lenses in shutters from old Ansco and Kodak folders; these are often around 100-140mm in focal length. I have access to a drill press so I was able to cut the exact size hole for each lens.
EDIT: The way I mounted the 50mm macro lens was by drilling holes in both the Mamiya RB body cap and the rear cap for the macro lens, and then gluing both caps together. The macro lens was simply mounted on the lens cap. It did cover 6x7 with no problems at macro range.
i've played with this a bit but the lack of a shutter is a pain in the ass. Most any large format lens longer than say 100mm will reach infinity no problem on the RZ. Rather than use a body cap (which don't lock), I'd cannibalize either an extension tube or a junk lens and take the mount off, and use that (mounted to another lens board of aluminum, or something. )
