The Minolta SR-T Series (Part II The SR-T102): Minolta launched the SR-T series in 1966 with the SR-T101. They were the first cameras to offer metering through the lens at maximum aperture using a brand new matrix metering system called the Minolta 'Contrast Light Compensator' system. A new range of MC lenses were developed that could communicate with the camera with a mechanical pin. The cameras are fully mechanical & built like tanks, the battery power is only needed for the light metering system. Naming of the SR-T series was a bit complicated as they used different names and numbers for the same camera in the different markets of North America, Asia and Europe.

In March 1973 Minolta released the SR-T102 as the new flagship camera. The SR-T 101 also continued to be produced. The SR-T 102 replaced the cold shoe with a hot shoe, added a full information viewfinder where both Aperture and  shutter speed could be seen. A split image rangefinder was also added to the focusing screen. Both the 102 & 102 continued in production until 1975.
