I C with Leica L-Mount

Viable interchangeable lenses
With the Leica I C and the possibility of using interchangeable lenses, Oskar Barnack's camera took its next great evolutionary leap.

Starting with the 1931 models, the laborious application of the lenses to the respective cameras was dropped – the Leica I C now had a standardized flange to film plane distance of 28.8 mm, to which all lenses were adapted.

In 1930 and 1931, Leitz expanded its as yet quite simple range of lenses, adding the Elmar 35 mm f/3.5, the Hektor 73 mm f/1.9, the Elmar 90 mm f/4 and the Elmar 135 mm f/4.5.

The age of the Leica screw mount cameras had begun, and with it the flexible possibility of using just one camera for different kinds of image.
