Introduced in December 1980, the Mamiya ZE-2 continued the quartz-regulated metal focal plane shutter that begun in the ZE camera. Both cameras have automatic exposure with aperture priority and, once it is determined, the aperture setting on both can be locked. The ZE-2 added a shake-prevention warning and a shutter-speed dial, and allowed a manual override (you can't select a shutter speed manually on the ZE). An electronic sensor coupled each lens to the camera through six gold contact points. The sensor automatically selected the slowest hand-held shutter speed possible for that focal length. Like the ZE, the Mamiya ZE-2 requires four (4) MS76 or equivalent batteries. It also uses the same sharp, Mamiya-Sekor E or EF optics that were found in the entire Z-series. However, perhaps because the ZE-2 is seen less often than its ZE cousin, it frequently brings a slightly higher price in auction. The Mamiya ZE-2 was also rebranded and sold in Germany as the Revue AM.
