FED 3

The FED 3 is based on the FED 2 and the dimensions of the two bodies are identical. The top deck is modified because the FED 3 has to have a shorter rangefinder base to make room for the slow-speed mechanism.

There are four models.

• FED 3a was introduced in 1961. It retained most of the FED 2 features, including the mushroom-shaped advance knob. The rewind knob is larger. The diopter is no longer adjusted by a lever but is adjusted by the ring over the viewfinder.
• FED 3b was introduced in 1963. It has a film advance lever and a flat top deck. It no longer has strap lugs.
• FED 3L is a FED 3a with an Industar 61 lens that has Lanthane glass. It was introduced along with the 3b in 1963.
• FED 3L/D is a FED 3a with an Industar 61 L/D.
