The Super Canomatic R 100mm f/2 lens should work on any Canon FL or FD mount body, with the exception of the T50 on which the use of a non-FD mount lens is severely limitated. As you noted, the aperture will need to be stopped down manually. There are a couple of Canomatic R lenses that might have clearance problems with the mirror, metering pins and aperture levers on the later FD bodies (A and T series). Check the instruction manual for the specific camera as this varies slightly from body to body.
