Leica Vario-Elmar-S 30-90mm /f3.5-5.6 ASPH.
The Leica Vario-Elmar-S 30-90mm f3.5-5.6 ASPH. combines a very versatile range of focal lengths, compact dimensions and low weight with excellent image quality over the entire focal length range, from infinity to close-up, at widest aperture and stopped down. Its performance makes the lens a full-fledged alternative to fixed focal-length lenses. The lens is primarily characterized by its compactness and light-weight; it boosting the photographer's flexibility, particularly in travel, fashion and photo journalism.
The Leica S-System lens uses a very sophisticated design: 14 lenses in four groups, including nine lenses with partial anomalous dispersion, three of which are fluoride lenses with particularly low dispersion for reducing chromatic aberrations. To minimize the monochromatic aberrations, the rear lens uses two aspherical surfaces; at the same time, an aspherical surface on the front lens element of the second group ensures close-up image quality, and contributes towards reducing of distortion. Sealed against dust and splash water guarantees outstanding durability and reliability.
Like all Leica S-lenses, the Leica Super-Elmar-S 30-90mm f3.5-5.6 ASPH. guarantees perfect images without digital correction, thus allowing photographers to focus purely on a creative image composition.
