Another of these cameras with proprietary mount that can only use the brand's lenses, which has limited their durability...
The Autoreflex T3 is automatic, speed priority (AE), as with the Canon AE-1 the lens iris ring has an AE position. If the diaphragm is in another position, the camera operates manually, the ligntmeter cannot be used.
The automation operated using two 1.35v mercury batteries, with current 1.5v LR44s the metering is distorted, which limits this camera to manual use or exposure on a shelf.
Mechanical shutter, with vertical metal curtains, 1s to 1/1000s + B, sync to 1/125s. A lever allows arming without advancing the film, allowing overprints. Another curiosity: the flash shoe is removable, but with a contact for sync.
Roberto gave me this bare body, Gilles gave me the 1.8/40mm, but I see it more often with a 1.7/50mm
