According to Minolta, development of the TC-1 began when an engineer questioned why SLRs were too bulky to carry day-to-day, but compact cameras sacrificed image quality. It took experienced technicians 45 minutes to assemble a single camera by hand, as the 150+ delicate, miniaturized parts used were not suited for a high-volume assembly line. The outer shell is made of titanium, which gave the camera its name ("Titanium Clad"). It is approximately the same volume as three 35mm film cartridges. One uncommon feature is the diaphragm, which used discrete circular
Waterhouse stops rather than a iris with multiple diaphragm blades. It has received praise for its
bokeh (out-of-focus characteristics). In 1996, the Camera Journal Press Club of Japan awarded the TC-1 with the Camera Grand Prix. A special edition for the Japanese domestic market, finished in black, was built to celebrate Minolta's 70th anniversary in 1998 and limited to 2500 examples. As part of the same anniversary, 2000 examples of the
G-Rokkor lens from the TC-1 were sold as a limited-production interchangeable lens in
M39 lens mount; unlike the TC-1, the M39 version of the
G-Rokkor was equipped with a 9-blade iris diaphragm, offering the additional aperture settings of , 11, and 22. All versions of the TC-1 were discontinued by 2007 ==Operation==
