|SONNAR||Optical design invented by Ludwig Bertele in 1929. Lenses that use this optical design are lightweight and of high speed. The Sonnar designation comes from German word Sonne which means "sun" and emphasized the lens speed of 2.0 (that was extraordinary rare in those days). In comparison with Planar the Sonnar design has more optical aberrations but the contrast and flare control is much better. In comparison with older Tessar design it has less chromatic aberrations and the lens speed is higher. Due to short working distance the Sonnar design could not be used in wide angle lenses for SLR cameras. That's why Sonnar lenses for SLR cameras are generally available with focal lengths of 135mm or more.|
|T*||The multi-layer coating is applied to the surface of lens elements. It boosts light transmission, ensures sharp and high contrast images, minimizes ghosting and flares.|

Design and Features
This lens with continuously adjustable focal length covers the range from 40 to 80 mm which is of special interest to the photographer. The lens is characterized by exterior dimensions which are even smaller than those of a medium telephoto lens.
The correction of the lens is such that - at medium focal lengths - its image quality is equal to that of the best fixed-focus lenses. Needless to say, image quality over the rest of the range meets all normal requirements. The plane of sharpness is maintained exactly during focal length change.
The Vario-Sonnar lens permits the desired angular field to be selected without time-consuming change of lens or viewpoint. Thus this lens has a photographic potential otherwise afforded only by several lenses with different focal lengths.
