The Canon EOS 100 is a 35 mm autofocus SLR camera introduced by Canon in 1991. It was marketed as the EOS Elan in North America. It was the second camera in the EOS range to be targeted at advanced amateur photographers, replacing the EOS 650.
Its headline features were near-silent film winding, input of EOS barcodeprograms, integral auto-zoom flash, twin input dials, an autofocus auxiliary light for low-contrast subjects, a maximum shutter speed of 1/4000s, and five fully automatic modes.
