Overview

The Carl Zeiss Jena Visionar 168mm f/1.9 is a massive, all-metal projection lens with excellent center sharpness and low mechanical vignetting, resulting in consistent bokeh across the frame. It covers full frame with only 1.5 stops of vignetting at infinity, which diminishes on closer focus. However, it lacks a helicoid and aperture diaphragm, requiring aftermarket adaptation and making it heavy (2525g) and cumbersome for fast action. It suits enthusiasts willing to adapt a unique, ultra-fast prime for static or deliberate shooting.
