Overview

The Sigma Mini-Wide 28mm f/2.8 is a compact, lightweight lens praised for its strong macro capability and good contrast/color reproduction. However, it exhibits chromatic aberration at wider apertures, with sharpness improving significantly when stopped down to f/5.6–f/8. Build quality is decent, but many copies suffer from haze due to coating issues. Compared to other 28mm lenses, it shows less contrast. It suits photographers seeking a versatile, affordable normal lens with macro function, particularly on APS-C bodies where it becomes a 42.8mm equivalent.
