The FED 4 is a later Soviet rangefinder produced from 1964 to 1980, featuring a built-in selenium light meter — unusual for Soviet cameras of the era. The meter is often no working or unreliable on most examples - mine is fine.

The camera itself remains a solid shooter. It retains the L39 mount compatible with the Jupiter and Industar lenses in the collection.

A more refined camera than its predecessors with an improved viewfinder and rangefinder.
