In August of 1991, this was the world’s first AF SLR camera which incorporated the concept of silent operation. The newly-developed silent mechanisms reduced film advance noise and rewind noise by one-eighth to one-half the level of previous models. The built-in flash’s coverage adjusts automatically (auto zoom) to suit the lens focal length. Red-eye reduction, second-curtain sync, and flash exposure compensation were other flash features. The Quick Control Dial on the camera back also enables real-time exposure compensation adjustment while you looked through the viewfinder. It was a feature-laden, mid-class multi-mode 35mm AF SLR. The camera was released in Europe as the EOS 100 and in Japan as the EOS 100 QDE. The EOS 100 Panorama was released in 1993 for the Japanese market only. The original price was a hefty $1,000.00 or more dollars with a 28 to 80mm f/3.5 to 5.6 lens. The body alone sold for about $675.00. Some of the other features are the self-timer, 13/16 by 1 3/8 inch LCD display, external 5 connector flash mount, ¼” 20 thread tripod mount, autofocus mode, Canon EF lens mount, 3 frames per second, shutter speeds up to 1/4000 of a second, and much more. The operation of the camera depends on a 6V 2CR5 battery.
