Excellent sharpness, high contrast and a superb resolving power over the entire focusing range are evident at full aperture. With itsaperture stopped down modestly to f/4, this versatile lens delivers a maximum of resolving power and contrast. It is all the moreimpressive because of its virtually perfect absence of distortion. That makes it a world-class lens among fast wide-angle lenses. Inspite of its high speed and its superb imaging performance, it is surprisingly small. Every Leica M camera fitted with this lens becomesa highly compact and elegant unit
