50mm · f/1.8
The Carl Zeiss Jena Tevidon 50mm f/1.8 is a C-mount lens originally designed for 16mm film cameras. It offers a fast aperture but is noted for strong vignetting and softness at f/1.8, improving when stopped down. Build quality is typical of vintage Zeiss lenses, with all-metal construction and smooth focusing. It suits users seeking a compact, characterful lens for APS-C or Micro Four Thirds cameras, though it may not satisfy those requiring edge-to-edge sharpness.
