|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
Like all Zeiss designs, this one was also developed in accordance with the established Zeiss practice of combining professional experience with a high-performance computer program devised by the company itself. The lens provides outstanding image quality and remarkably good image field illumination, both achievable when the diaphragm is fully open.
Alongside a wide-angle lens, this Sonnar® lens, with a focal length approximately three times as large as the diagonals of the 35 mm format, is perhaps the most widely required interchangeable lens.
Regardless of whether it is landscape photography, fauna and flora studies, family shots or portraiture work, there will never be any shortage of subjects for which the 135 mm focal length is particularly well-suited. With its help the photographer can bring up close fairly distant subjects without creating the flat perspective that sometimes mars a picture. On the other hand, picture-filling details can be selected without having to approach all that close. And finally, thanks to its moderate tele-perspective effect it is admirably suitable for portraits, either with the diaphragm fully open or slightly stopped down.
