Schneider's budget enlarging lens — the Comparon 50mm at entry-level specification.
Schneider-Kreuznach has been one of the world's leading optical manufacturers since 1913, producing precision lenses for photography, cinema, and industrial applications. The Comparon is Schneider's budget-grade enlarging lens using a simpler optical formula, positioned below the Componar and Componon ranges and intended for casual darkroom use.
50mm focal length, f/3.5 maximum aperture, basic anti-reflection coating, M39 thread mount, designed for 35mm negatives.
The Comparon delivers acceptable results for casual black-and-white darkroom use at small-to-medium print sizes. Optical quality does not match the Componar or Componon; for colour printing or critical fine-art work, Schneider's higher-tier offerings are preferable. The Comparon is a budget entry point with Schneider heritage.
Inspect for haze and fungus; budget-grade Schneider lenses may show more susceptibility to coating degradation than the premium range. Check aperture blades and M39 thread.
