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