Apochromatic correction and an aspherical lens surfaces are brilliantly combined in this compact medium telephoto lens to deliver exquisite performance.

Two out of its five elements are high-refraction glass.

Two other elements feature anomalous partial dispersion.

Consequently, the brilliance and resolution are exemplary across the entire image field, even at maximum aperture.

This performance can be improved only slightly by stopping down.

Light falloff is minimal even at full aperture. The wide f/2 aperture and excellent contrast characteristics result in a particularly bright viewfinder image, enabling reliable, accurate focusing even when there is little light.

The close-up limit is 0.7 meters (27.5 in), and in the extended close-up range you can fill the frame with a subject measuring 14x21 cm (5.5 x 8.25 in).

With the LEICA APO-EXTENDER-R 2x, it becomes high-performance 180 f/4 mm long telephoto.
