The Mamiya ZM is a 35mm camera released in October 1982. It was the last Mamiya 35mm camera produced. Designed by Tsuneaki Munakata, it is an advanced version of the ZE-2, incorporating some features from the ZE-X. The ZM has an aperture-priority automatic time control, which is based on center-weighted TTL readings. It features a metal electronically controlled automatic shutter-speed range from four seconds to 1/1000, and a manual range from two seconds to 1/1000, plus Bulb mode. The camera is powered by two 1.5v LR44/SR44 coin-type batteries.
