The Mamiya RZ67 is a medium format film SLR introduced by the Mamiya Camera Co. Ltd in 1982. It is the successor to the earlier, fully mechanical, Mamiya RB67. The RZ67 features an electronically controlled shutter which ranges from 8 seconds to 1/400th of a second, and a bulb setting. The RZ67 uses Mamiya-Sekor Z lenses electronically, or can use Z lenses at 1/400th of a second and earlier mechanical lenses with its mechanical backup mode.
