A German camera brand from Wetzlar. Oskar Barnack built a small camera for 35 mm cinema film at the company Ernst Leitz, and the Leica I went on sale in 1925.
The Leica made small, fast, handheld photography practical and helped create modern photojournalism and street photography. Henri Cartier-Bresson worked with a Leica for most of his life. The Leica M system started in 1954 and is still made today. See also rangefinder.
