Pick the Sigma 105mm f/2.8 if you need true 1:1 macro reproduction, a brighter f/2.8 aperture for better low-light performance, and a fixed focal length for sharper images. The Sigma 28-300mm stays the better choice if you prioritize versatility with a broad zoom range and don’t require the wider aperture or extreme close-up magnification.
