LEICA ELMAR-M 24 mm f/3.8 ASPH.
The compact, high performance wide-angle lens
The practical wide-angle lens

This lens with its handy dimensions is distinguished by very high image quality and a very wide image angle - making it a particularly practical wide-angle lens. It is suitable for a very wide range of uses for everything from daytime reportage to landscape and travel photography. Even at the initial f-stop of 3.8, contrast and detail rendering are already excellent. At the medium f-stops, the depth of field is so large that it can even reproduce entire scenes in sharp focus. That makes it excellent for use in combination with the snapshot mode of the Leica M9.

LEICA M8.2, ISO 160, f/4.5, 1/250 s
