When the leading German optical manufacturer, Carl Zeiss of Oberkochen, formed a partnership with one of the leading optical firms of Japan, Yashica Kyocera, to release a completely newly designed line of electronic cameras, it was Zeiss' part to contribute their knowledge of special glass sorts and lens construction. As their patent on the classical Planar design had run out of legal production and could therefore
 be replicated easily by their competitors, the people at Zeiss decided to computate a new Planar design on new principles -- the Zeiss Planar 1.7 / 50mm with 7 elements in 6 groups was born.

Carl Zeiss was the first to utilize complicated mathematical calculations for their microscopes and photo lenses around the middle of the 19th century. At one time, Zeiss formed a partnership with an emerging glass foundry that experimented with new glass sorts. In the 1940s, Zeiss patented the first anti-reflective coating, their T* coating, that is also applied to the lens on sale.

Carl Zeiss Planar 1,7 / 50 T* Serial Number 6336013

This is an excellent lens that will never be built again!

Condition of the lens: Lens is in full working condition, almost no external signs of use to the barrel (please see photos). It might pass as "mint." The glass is clear and without scratches, as far as I can see. The aperture ring is moving freely, with no oil on the blades. The focussing helicoid is moving easily as well, everything working as it should. PLEASE NOTE: In some marginal places on the surface of an interior glass element, dirt can be seen (please see photos above). I have tested the optical performance of this lens and can see no degradation. This dirt can be easily removed. I have reduced the price for this lens so that you may acquire it at a good price. Perhaps you can clean the lens yourself or a workshop in your contry will do it for you cheaply.
