It was aimed at the advanced amateur market, and featured a rear command dial, support for custom functions, and an optional BP-50 battery grip, with a dedicated portrait shutter release.

The Japan-only EOS 55 was also available in an all-black version[4] – rather than only the standard black and silver colour scheme – and included a panorama option.

Sliding the button at the bottom of the rear of the camera causes panels to mask off all of the negative except for a 13 mm x 36mm strip in the middle.

Canon's previous TTL system metered light reflected from the film onto a sensor during the actual exposure.
