"In March 1973 Minolta released a new flagship model camera, replacing the SR-T101, which while still in production, was relegated to a secondary position. The new camera was the SR-T 102. At this stage Minolta also commenced its practice of naming cameras differently in different markets, which it carries on to this day. In this respect, the SR-T102 was named the SR-T 303 in Europe, and the SR-T Super in Asia-Pacific.
Changes to the SRT101 are small, but significant to the advanced amateur photographer. Firstly, the camera included a full information viewfinder, whereby the lens aperture and selected shutter speed are shown in the viewfinder display. A photographer need never take his eye away from the finder now to check any details. Secondly, a split image rangefinder was added to the focusing screen as a new focusing aid. A multiple-exposure capability was also added through the use of the film release button. While this could be done on the other models, it was unpredictable and the photographer needed to hold the film rewind knob to ensure that the film was not advanced partially during the process. This was no longer a problem with the new model. Finally, the cold flash shoe was replaced by a hotshoe, eliminating the need for use of a sync cord when using electronic flash. "
