Extremely rare and special lens, only around fifty were ever made. This lens is a collector's item. Glass is in perfect condition but barrel of lens shows signs of use. Condition is good. Perfect working order. My tests of the lens are extremely sharp. I'm very sad to have to sell this incredible lens.
Originally designed for the NASA moon landings, the 105mm UV-Sonnar f/4.3 is a special design consisting of fluorite and quartz elements with excellent light transmission in the ultraviolet region of the spectrum. The lens also features extensive chromatic correction both for the ultraviolet and the visible ranges and is therefore suitable for use in both these ranges.
The UV-Sonar lens features high image quality and superb distortion correction throughout the wide range from UV to VIS. In UV photography, focusing can be performed using visible light without the need for further adjustment. Fields of application include technical and scientific photography, such as studies of textiles, printing forgeries, and all types of material examination, including by museum archivists to analyze paintings. A field of special interest is extraterrestrial UV photography.
