Leica's compact 90mm for the CL — the Elmar-C designed for Leica's smallest M-mount camera.
The Leitz Elmar-C 90mm f/4 was introduced in 1973 specifically for the Leica CL, Leica's most compact M-mount camera. The C designation indicates the CL-optimised version. At 90mm f/4, it provides a portrait-length telephoto in an exceptionally compact package — smaller and lighter than any other Leica 90mm option. Despite its budget positioning, it delivers genuine Leica optical quality.
Optical performance is good — surprisingly so for such a compact lens. Sharpness is very good from f/4 and excellent stopped down. The simple 4-element Elmar design is well-optimised for the focal length. Colour rendition has the characteristic Leica neutrality. The modest f/4 aperture limits shallow depth of field but ensures consistent sharpness across the frame.
Leica M mount with rangefinder coupling. Filter thread is 39mm (E39). Weight is approximately 230 grams — one of the lightest Leica 90mm lenses. Build quality is excellent with precision Leitz engineering, though simpler than the more expensive Elmarit and Summicron 90mm options. The focus ring is smooth with accurate rangefinder coupling.
Available on the used market at relatively affordable Leica prices. Check rangefinder coupling and smooth focus. An excellent compact 90mm for Leica M shooters who value portability over maximum aperture. The E39 filter thread matches many other Leica lenses. A hidden gem in the Leica lineup — compact, sharp, and more affordable than Summicron alternatives.
