Sigma 28mm f/2.8 Mini Wide Macro C/Y Mount Lens Review

The Sigma 28mm f/2.8 Mini Wide Macro is a compact manual-focus lens designed for the Contax/Yashica mount system. At 28mm, it offers a useful wide angle of view for general photography, and its macro designation suggests closer-than-typical minimum focusing distance for a lens of this focal length. The f/2.8 maximum aperture is modest but typical for a compact wide-angle prime of this era.

This particular listing from KEH is for a used copy in Excellent Plus condition, priced at $46. The C/Y mount means it's intended for vintage film bodies or adapted to modern mirrorless cameras, where it can serve as an affordable manual-focus option for shooters looking to experiment with older glass. The 52mm filter thread is a common size, making it easy to find compatible filters. Without user feedback or contemporary reviews, it's difficult to assess optical performance, build quality quirks, or how well it holds up under real-world use, but the condition grade and price point position it as a low-risk entry for anyone curious about legacy Sigma glass on adapted systems.
