Descripción

The mid-1970s are an intriguing period for the history of the Leitz factory. The classical rangefinder system (embodied in the Leica M4) could not compete with the powerful Japanese reflex systems and the compact camera was growing rapidly in popularity. History often repeats itself and the current debate about the status and future of the mirrorless compact system camera is a rehearsal of that historical debate. Leitz defended its position vigorously on three fronts: The M5, R3 and CL.

For the Leica CL (the “Baby-Leica”) Leitz designed its dedicated set of lenses, the Summicron-C 1:2/40mm and the Elmar-C 1:4/90mm. This 90mm lens, designed in Wetzlar, delivers already at full aperture excellent quality with a high contrast image over most of the picture area. Close up performance is excellent too and distortion is nonexistent, making the lens suitable for reproduction work.

It might be the case that Leitz optimized the design for close to medium distances because in this range the CL would be used most often. The lens prescription of the Elmar-C has much in comon with the later macreo-Elmar-M 90 mm.

C-Lenses couple accurately to the M-body (the bayonet is the same), but focusing errors might occur. It was a very popular lens with almost 49.000 units allocated. Presumably this lens graced many Leica M bodies because of its performance and compact size.
