About Canon A-1 from Wikipedia, the free encyclopedia
The Canon A-1 is an advanced level, interchangeable lens, 35 mm film, single-lens reflex (SLR) camera. It was manufactured by Canon Camera K. K. (today Canon Incorporated) in Japan from April 1978 to 1985. It used a horizontal cloth-curtain focal-plane shutter with a speed range of 30 to 1/1000th second plus bulb and flash synchronization speed of 1/60th second. It has dimensions of 92 mm height, 141 mm width, 48 mm depth and 620 g weight. Unlike most SLRs of the time, it was available in only one color; all black. The introductory US list price for the body plus Canon FD 50 mm f/1.4 SSC lens was $625. Note that while the list price was $625, this camera generally sold for 30 to 40% which is roughly $375 to $435.
The A-1 is an historically significant camera. It was the first SLR to offer an electronically controlled programmed autoexposure mode. Instead of the photographer picking a shutter speed to freeze or blur motion and choosing a lens aperture f-stop to control depth of field (focus), the A-1 has a microprocessor programmed to automatically select a compromise exposure based on light meter input. Virtually all cameras today have at least one program mode.
