Mint and complete set including lens with perfect clean optics, caps, the special Carl Zeiss density filter, finder, instructions, guarantee card and maker's box with matching number. Carl Zeiss first announced the 15mm Hologon as a lens fixed to the body with a modified Contarex camera. From 1972, Zeiss also manufactured it for Leitz in Leica M mount. In the Leitz catalogue it was offered as “Carl Zeiss Hologon for Leica M” until 1975. The Hologon was a lens with 110° angle of coverage, designed as a three element system only with two thick negative meniscus elements in the front and back, as well as a converging element in the centre. As a lens almost without distortion, it did show slight vignettation, compensated with a special centrally graduated density filter. A large brightline finder was part of the Hologon outfit as well. The lens was produced in very small numbers only; it is a rarity to find a complete set in good condition today.

极佳状态且完整的套装，包括镜头（光学部分完美无瑕）、镜头盖、特别的卡尔蔡司中灰滤镜、取景器、说明书、保修卡和带有匹配编号的原厂包装盒。卡尔蔡司最初宣布 15mm Hologon镜头是与经过改装的 Contarex 相机固定在一起的。从 1972 年起，蔡司也为徕兹（Leitz）制造了徕卡 M卡口的版本。在徕兹的目录中，这款镜头被称为 “徕卡 M用卡尔蔡司 Hologon”（Carl Zeiss Hologon for Leica M），并一直销售到 1975 年。Hologon是一款视⾓为 110°的镜头，设计为仅由三个镜片组成的系统，前后各有两个厚的负弯月形镜片，中间有一个会聚镜片。作为几乎没有畸变的镜头，它确实显示出轻微的渐晕现象，但可以通过一个特殊的中心渐变中灰滤镜来补偿。Hologon套装中还包括一个大型的明亮取景器。这款镜头的生产数量非常少；如今要找到一套完整且状态良好的Hologon镜头实属罕见。
