    Overview

    The Carl Zeiss Jena Visionar 77mm f/1.6 is an ultra-fast projection lens with excellent center sharpness and good optical correction for its age. However, it lacks a focusing helicoid and aperture diaphragm, requiring modification for camera use. Its all-metal build is solid, but weight and lack of diaphragm are weaknesses. It suits photographers willing to adapt it for creative, wide-aperture work, but not for general or infinity shooting.
