    Overview

    The Rathenower Optische Werke Visionar 109mm f/1.6 is a fast cinema projector lens, optically identical to the Carl Zeiss Jena version but often cheaper. It covers full frame with moderate vignetting (1.5 stops) and well-behaved mechanical vignetting, but exhibits significant field curvature and cannot be stopped down. Build is solid metal but lacks a focus helicoid and aperture diaphragm, requiring modification for camera use. Suits users seeking a unique, fast portrait lens who are willing to mod or adapt it.
