The Topcon Super DM is a manual focus 35mm film SLR camera from Tōkyō Kōgaku.

It uses an interchangeable lens system based on the Exakta lens mount. The most common lens with this camera is the RE GN M 50mm f/1.8 or f/1.4 Topcor. The focal plane shutter has speeds from 1s to 1/1000 plus B. The shutter release button has a standard cable release screw and surround by a lock to prevent accidental exposures. Flash sync is at 1/60 a sec. It features an metering system using a CdS photo cell. The meter has a range of 2 to 16 EV at (ASA 100, f/1.4), settable to film speeds from 25 to 1600 ASA. Focusing is controlled on the lens barrel, with a split image rangefinder on the focusing screen. The focus screens are interchangeable with 5 different types. The film transport uses a single stroke film advance lever. A motor drive option is available. Film is rewound with a rewind crank and is powered by a 1.3v mercury battery.
