The Sure Shot (US)/AF35M (Europe)/Autoboy (Japan) was an early example (1979) of an active autofocus camera. According to the Canon Camera Museum, "This was the world's first lens-shutter 35mm autofocus camera". In fact, the Konica C35 AF had used an autofocus mechanism two years earlier, but that was system was "passive" and the active CAFS (Canon Auto Focus System) (using a near-infrared emitting diode (IRED) and photo diode receiver) came to dominate the market. The AF35M was the first model released in Canon's huge-selling Sure Shot/Prima/Autoboy series.
