One of the last film cameras I ever bought. The EOS-1 was the flagship Canon SLR at about the time I rejoined Tony Stone Images to help setup and run the new Electronic Imaging Department in 1990/1991.
This camera (unlike any other I had before it) had auto focusing and a built in motor drive to wind the film on. Its top plate had an LCD to allow visual feedback of the controls and many buttons to manage ISO, shutter speed and aperture. For all intents and purposes this was the same as the digital Canon 1Ds which came much later. The only clue it was not digital was the holder to put the end of the cardboard film box to remind you of what film was loaded instead of a playback screen.
This camera was purchased on 29th December 1992.
