The Auto-Lux 35 is a 35mm fixed lens SLR introduced in 1963 by Mamiya. It features a Copal-X leaf shutter with a Mamiya Sekor 48mm f/2.8 3 group, 3 elements lens. The camera has an external selenium metering. This allows for shutter priority auto-exposure although the camera can also meter in manual mode. The camera also has a Bulb setting which is accessible after pressing a switch on the lens barrel. The leaf shutter allows flash sync at all shutter speeds. The Mamiya Auto-Lux 35 was rebranded in European markets as the Rank Mamiya Auto-Lux 35, Revue Auto-Lux 35, and the Porst Autoflex. The shutter speeds were 1/15 to 1/500 of a second plus B and capable of using ASA 10 to 400 film. The camera also has an X type by PC-sync socket in the front and mount point on camera viewfinder head. The lens filter thread is 40.5mm and the lens minimum focus range is 3 feet or .08m. The camera also has a single action film advance lever, fold down rewind crank handle, recessed rewind release button on the bottom, frame counter, and a ¼” 20 thread tripod mount. The last Mamiya Auto-Lux 35 in all its iterations was made in 1967.
