The Super-Canomatic R 100mm f/2 is a fast short-telephoto prime made by Canon for the R bayonet mount, the company's first SLR system introduced with the Canonflex in 1959. The 'Super-Canomatic' designation indicates an automatic diaphragm that stops down at the moment of exposure, a feature Canon promoted on its early R-series optics.

Sales data for this lens is very thin: a single UK auction hammer result of £170 is on file from October 2023, and that wholesale, saleroom-level figure is the only firm reference point for what one is worth today. Because the R mount had a short production life and 100mm f/2 examples surface infrequently, individual prices can vary considerably with cosmetic condition, glass clarity and the presence of caps and case.
