Extremely fast LEICA telephoto zoom (F1.7) with 50-100mm KB focal length, ideal for flexible shots in low light through to cropped portraits. The elaborate construction of LEICA lenses not only enables brilliant sharpness right to the edges, but also minimal distortion and edge darkening. An aperture ring for stepless adjustment of the exposure and a focus clutch mechanism for direct manual focusing facilitate operation. It is also characterized by a dust and splash-resistant design and can be used in the most adverse conditions down to -10° C. In addition, the lens also allows strong close-ups with 0.42x magnification at a distance of 31 cm, as well as minimized focus breathing.
