Leica 50mm f3.5 Elmar (Type I) (ELMARCHROM / ELMAR) - Lens
Manual focus normal collapsible lens made for LTM M39 thread mount 35mm rangefinder cameras by Leica starting in 1932. The 50mm f3.5 Elmar was the first standard lens made for the Leica system. It underwent many changes during its production, from its initial computation in 1923 to the end of production in 1959. This version of the lens, codeword ELMARCHROM (later ELMAR), was introduced in 1933 and was available in a chrome-plated body. In 1936, production of the older nickel-plated version (ELMARKUP) ceased. This Type I chrome-plated version was available up until the introduction of a new optical formula, Type II, in 1951. It, however, experienced many changes before that: in 1935, an infrared marking was added to the focus scale, in 1946 (at serial 581.501), the lenses were coated, in the late 1940s, after the war, the aperture scale had changed from f3.5 - f18 to f3.5 - f16 and finally to f3.5 - f22. Metal body available in silver chrome (ELMARCHROM / ELMAR).
