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.
EOS 100 panorama (released in November 1993) was an EOS 100 QD with a panorama frame.(Japanese version only)
