Information AboutLeica |
Leica is the name of several AG which produces geodetic equipment; and Leica Microsystems GmbH, which produces microscopes. Leica Microsystems GmbH is the owner of the Leica brand, and grants licenses to Leica Camera AG and Leica Geosystems. LEICA CAMERA HISTORY The Leica was the first practical to be the best choice, leaving room for a 36-exposure film length (originally 40 exposures, but some films were found to be thicker). Barnack's words, "Small negatives—large images", would soon change the world of photography. The concept was developed further, and in 1923 Barnack convinced his boss, Ernst Leitz II, to make a prototype series of 31. The camera was an immediate success when introduced at the 1925 Leipzig , Germany Spring Fair as the Leica I (for Leitz '''Ca'''mera). The compactness of the camera, and its reliability and excellent lens, made it a success. The lens was the 4-element Elmar 50 mm f/3.5 Objective designed by Dr. Max Berek at Leitz, influenced by the Zeiss Tessar . The focal plane Shutter had a range from 1/20 to 1/500 second and Time (marked ''Z'' for ''Zeit''). In 1930 the ''Leica I Schraubgewinde'' with an exchangeable objective system based on a 39 mm thread was produced, with a 50 mm Normal Lens , a 35 mm Wide-angle Lens and a 135 mm Telephoto Lens available. The ''Leica II'' came in 1932, with a built in Rangefinder coupled to the Lens focusing mechanism. This model had a separate viewfinder (showing a reduced image) and rangefinder (showing a double image which was properly focused when it became one image). The Leica III added slow shutter speeds down to 1 second, and increased rangefinder magnification to 1.5X for more accurate focusing. The model IIIa, introduced in 1935, added the 1/1000 second shutter speed. Also significant about the IIIa is that it is the last model made before Barnack's death, and therefore the last model he was wholly responsible for. Leitz continued to refine the original design through to 1957. The final version, the IIIg, included a large viewfinder with framelines, similar to the M3 finder, but still with the separate view — and rangefinder. These models all had a functional combination of circular dials and square windows that was quite esthetically pleasing, although somewhat busy in appearance. All remain perfectly usable today if serviced properly. |
