50mm · f/4
The Schneider Kreuznach Componon 50 mm f/4.0 is an enlarging lens suited for macro photography at magnifications around 2.8x. In tests, it showed good center sharpness but was outperformed by other lenses like the Rodenstock APO-Rodagon-N in corners and chromatic aberration control. Build is typical for enlarging lenses, with a fixed aperture. It is a decent budget option for macro enthusiasts, but those seeking top corner performance may prefer alternatives.
