    Overview

    The Carl Zeiss Jena Visionar 109mm f/1.6 is a fast, inexpensive cinema projector lens originally lacking a focusing helicoid and aperture diaphragm, requiring modification for camera use. Optically, it covers full frame with moderate vignetting (1.5 stops) and well-behaved mechanical vignetting, but exhibits field curvature and cannot be stopped down, limiting its use for infinity or architecture. Build quality depends on the mounting solution; the lens itself is solid metal with six glass elements. It suits photographers seeking a unique, fast portrait lens who are willing to mod it, but not for general-purpose or stopped-down work.
