LEICA 35 mm f/2 ASPH. SUMMICRON-M

Aspherical lens

ENGINEERING DRAWING LENS SHAPE

Excellent sharpness, high contrast and a very good 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.
