Leica Vario-Elmar-S 30-90mm f/3.5-5.6 ASPH
The Leica Vario-Elmar-S 30-90mm f/5.6 ASPH is equivalent to 24-72mm in the 35mm format. This is the only zoom lens in the Leica S-system. For a medium format lens, it is particularly compact and lightweight offering high image quality across its zoom range.
The optical design comprises 14 elements in 11 groups. Three low-dispersion fluoride elements correct chromatic aberrations. Two aspherical surfaces on the rear element and another on the front lens of the second group maintain consistent imaging performance and minimal distortion at shorter distances. The effects of vignetting are imperceptible at all focal lengths.
