With the Leica Apo-Summicron-M 90mm f/2 ASPH. light fall-off is very low. Its fast aperture lets you shoot at a relatively short exposure time – even in dim light. The result is a minimized camera shake, even when shooting street scenes from a distance. Thus the APO-Summicron-M 90mm f/2 ASPH. is ideal for photojournalism, theatre and even portrait photography.
Apochromatic colour correction and an aspherical lens surface are combined for the first time in the Apo-Summicron 90mm f/2 ASPH. Of its individual elements, two are made of high-refraction glass, while two others feature anomalous partial dispersion. Its brilliance and quality of resolution are exemplary even at full aperture.
