The Leica VIDOM black paint nickel zoom viewfinder, produced 1932–1936, is a variable-magnification optical finder with 3× to 13.5× selectable ratios for 3.5 cm to 13.5 cm Leica lenses. Its complex 5-element 4-group Galilean telescope design incorporates a movable negative lens group for continuous focal-length adjustment. Nickel-plated brass housing with black paint finish, parallax compensation via rotating cam, and integral bubble level. Rare early accessory directly tied to the introduction of interchangeable lenses on the Leica II and III.
