Leica 135mm f3.4 APO (E49) Lens Overview

Impressive all-rounder
A telephoto lens of uncompromising quality with apochromatic color correction, the resolution, contrast, and sharpness of the 135 mm APO-TELYT are optimal at all apertures. It also has very little light falloff even at maximum aperture and minimal distortion, resulting in top pro-level performance. This lens can render the finest details clearly and in rich contrast. As the longest focal length in the Leica M system, it's idea for shooting over long distances and is the perfect completion of any high-class outfit. It permits distinctive landscape shots with typical telephoto effects: the foreground and background are visually compressed. Moreover, it enables frame-filling portraits to be shot from afar, so the subject is undisturbed.
