This lens is unique because apochromatic correction and an aspherical surface are combined for the first time. Two of the five lens
elements are made of high-refraction optical glass, and two others make judicious use of anomalous partial dispersion. Brilliance
and resolving power are already outstanding at full aperture. Artificial vignetting is extremely low. These features lead to superlative
results ¨C in every application: such as portraiture, reportage or studio photography. In addition, its compact design and high
speed make it ideal for hand-held photography.
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 minimise the effects of camera shake, for instance when photographing street scenes from a distance.
