This camera had unusual features such as shutter speed-priority AE, maximum-aperture TTL metering and AE, a bright aerial image viewfinder, and focal-plane shutter. The front lens element was also interchangeable.

The camera had a built-in rear lens consisting of 3 elements in 2 groups. Besides the normal EX 50mm f/1.8 lens, two other interchangeable front lens elements were available: EX 35mm f/3.5 and EX 95mm f/3.5.

Centerweighted averaging metering was incorporated for easy operation. For lenses with different maximum apertures, the f-number could be adjusted manually to compensate.
