Carl Zeiss Otus Apo Distagon 55mm f1.4 ZF.2 T*The Carl Zeiss Otus Apo Distagon 55mm f1. 4 ZF. 2 T* is a no compromises "normal" lens for Nikon F mount. Well, there's one compromise: it's huge, and it weighs more than a kilo. Also, it's manual focus. Other than those two compromises, though, no compromises! This is a beautiful, sharp lens for folks who are looking for the best possible performance at any aperture. Smooth focusing, clean glass. Includes hood.
