Leica M39 system

Leica is a brand name synonymous with 35mm photography and rangefinder cameras. Leica introduced many features which were then adapted by other 35mm cameras. Interchangeable lenses, the focal plane shutter and the lens-coupled, built-in rangefinder, to name a few.

The interchangeable Leica lenses were offered in a large variety of types ranging from wide-angle to telephoto, ensuring excellent results in all branches of amateur photography and most specialized professional work. Their exceptional light-gathering qualities, resolving power, remarkable depth of field and unexcelled color rendition helped to develop the Leica system of photography.
