An extremely rare lens in excellent condition and with clean optics and complete with all four distance rings (4457 for infinity, 4149 for 100m, 4149 for 50m and 4149 for 20m). The 20m ring is the original, made by Leica. All the other rings, as well as the lens mount, were made by Ottmar Michaely in Germany to the original specifications.
Leitz Canada’s lens design legend Dr Walter Mandler was not only responsible for lenses such as the famous 50 mm Noctilux f/1.0 or the 180 mm APO-Telyt f/3.4, but also breathtaking lens designs made to military orders. The 90 mm Elcan-M f/1.0 lens (C164) is, without any doubt the most stunning Leica lens designed by Dr Mandler and made by Leitz Canada for the U.S. Navy.
The lens was designed as a fixed-focus system, with setting rings for different focal distances. Only ten 90 mm F/1.0 Elcan lenses have been completed, the one offered here is the second made.
