The Leica 135mm f/3.4 APO Telyt M Manual Focus Lens the two previous M lenses of the same focal length (f/2.8 and f/4, respectively). The sharpness, contrast and resolving power of this unique lens are impressive, even at full aperture. Other plus points are its modest weight, its handiness, and its ease of operation. And it comes with a built-in sliding lens hood.
F stop range - 3.4-22
Closest Focusing Distance - 5'
Maximum Magnification - 1 - 9
The Leica APO-Summicron-M 50mm f/2.0 ASPH Lens represents a true milestone in photographic lens development. You need look no further than the MTF chart to understand what makes this piece of equipment so significant: At an aperture of f/5.6, the lines for both tangential and sagittal structures are absolutely flat--meaning the lens has no image degradation whatsoever. The graphs for f/2.0 and f/2.8 are highly impressive, as well. This is an achievement previously believed by many to be impossible in the field of optics.
