Sometimes the vital statistics of a lens hardly change over decades. Such a lens evidently fulfills a need for photographers. The first 90 mm lens in the Leitz tradition was introduced in 1931, but the first design with an aperture of 1:2.8 was made by Schacht in 1953. It is easy to design a long focus version with good image quality. Leitz had such a lens in the M-range since 1959. A telephoto lens is more difficult to create: the effective focal length is longer than the length from the first surface to the focal point and in this design a positive front component is followed by a negative rear component. It is incorrect to label any long focus lens as a telephoto lens. A short physical length has obvious advantages for the user and this Canadian designed Elmarit-R, introduced in 1964 (together with the original Leicaflex) it is an excellent design. A medium to high overall contrast is coupled to a very even edge-to-edge definition of very fine detail that is recorded crisply.
