The Canon EOS 50 (also known as the ELAN II in America and the EOS 55 in Japan) is an autofocus, autoexposure 35mm SLR camera. Three variants were produced. The E variant had the addition of eye-controlled autofocus, and partial metering, while the QD variant had a date and time imprint function on the film door.

The EOS 50E variant introduced an enhanced version of the 3-zone eye-controlled autofocus system that was first seen on the EOS 5 camera. The EOS 50 was also the first camera to implement Canon's E-TTL flash system. Canon's previous TTL system metered light reflected from the film onto a sensor during the actual exposure. E-TTL on the other hand fires a low-intensity pre-flash before exposure, and meters the reflected light through the camera's normal metering system.

The EOS 55 differs from the other versions in that it has a panorama option. Sliding the button at the bottom of the rear of the camera causes panels to move into position inside the camera, blocking all of the negative except for a 13 mm x 36mm strip in the middle. When print film is subsequently developed in a developing machine that is sensitive to Advanced Photo System (APS) negatives, the machine will automatically print a 4"x12" "panoramic" print instead of a regular 4"x6" print. Sales of the EOS 50 began in September 1995, and ended after the introduction of the replacement model, the EOS 30 in October 2000.
