With a dead battery, all functions will continue to work except for the meter. The SR-T 101 uses a cell for the metering system only.The SR-T 101 had additional features which set it apart from many other of that time, like, a mechanical and a preview aperture stop-down button.The film advance lever automatically cocks the shutter, preventing double exposures. The SR-T 101 had a cloth with speeds from 1 sec to 1/1000 sec.What is actually transmitted is not the aperture itself, but the offset between the selected aperture and full aperture. This way, the position of the aperture ring MC tab communicated mechanically to the metering system inside the camera. This was possible thanks to the fact that Minolta had placed the aperture ring on its MC lenses close to the camera body. The Minolta SR-T 101 was one of the first cameras to have full-aperture metering. You can't read anything from Minolta's serial. With the same lens model, is larger serial numbers always meaning they. The second image shows the indicator meter in battery control mode: needle over the little rectangle means correct voltage. The body is a direct continuation of the model V of 1962, itself an innovative camera, with the addition of through-the-lens (TTL) metering and additional features. Sales began in April 1966 and it stayed in production with only minor changes for ten years, the result of the thorough development effort that was put into the camera. Please ONLY post pictures taken with the lens in the title- or start a new thread.Contents The camera The Minolta SR-T 101 is a camera made by, premiering in the March 1966 Japan Camera Show. This thread is open for C&C and for posting additional pictures. The later 40mm lenses designed for Minolta CLE are multi-coated and serial number is on the lens barrel. The 'QF' marking simple denotes the optical formula of the lens 'Q' denotes that the lens is made of four groups, and 'F' denotes these groups are made of six elements. Later versions lose the 'QF' marking, but retain the lens serial numbers on the filter ring.

The CL generation lenses are single coated and have the lens serial numbers on the filter ring. Optical scheme based on Summicron-C 40/2. M-Rokkor 40mm F2 (for Leitz Minolta CL).
