==History==
The Leica Standard, Model E was the fourth version of the original ''35 mm'' Leica camera to be launched from Ernst Leitz in Wetzlar, Germany. The concept was conceived by their employee Oskar Barnack in 1913 at which time two prototypes were built. However, it was not until 1924 that Leitz decided to go ahead with the concept and production began the following year. By the end of the decade, the camera had been perfected and full-scale production was established.
The Leica Standard was introduced as a basic model by Ernst Leitz, Wetzlar in October 1932. The camera was in production at the same time as the Leica II and Leica III models that have coupled rangefinders; the latter also has the faster speed of 1/1000 sec. It has a standardised lens mount with distance from film plane to lens flange fixed to 28.8 mm, a Leitz standard. This feature was first seen on late Leica I model C cameras in 1931, and all Leica II, Model D from 1932, identified by a "0" (zero) stamped on the lens mount flange at the top, to indicate the implementation of the standard, a practice that was continued for some time. It is found on early Leica Standards as well. On the back of these models there is a hole covered by a black plug, presumably for back focus calibration. The original lens for the Leica Standard when introduced was the ''Leitz Elmar 1:3,5 F=50mm'' in a collapsible nickel-plated focusing mount with infinity catch.
