عدسة أبو-سميكرون -إم 90 ملي متر f/2.0 ASPH أسود

Apochromatic colour correction and an aspherical lens surface are combined for the first time in this lens of this type. Of its five 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. Light falloff is very low. Its fast aperture, for a 90 mm lens, lets you shoot at relatively short exposure times even in dim light, helping to minimize the effects of camera shake, for instance when photographing street scenes from a distance.
