LEICA SUMMICRON-M 28 mm f/2 ASPH.
1
This fast wide-angle lens is especially compact and its imaging performance is outstanding at f/2. The rendition of the finest details
results in pictures with an extraordinary depth effect. Even in critical lighting conditions, for example in backlit situations, distrac-
ting reflections and flare are largely eliminated. Because of its large aperture of f/2, it can also be used for selective sharpness set-
tings in the wide-angle range. And when pictures are to be taken without flash under unfavorable light conditions at twilight or in
sparsely illuminated rooms, this lens is highly recommended.
