I just recently acquired a new lens, a Sigma 50mm f/2.8 macro lens. The lens isn’t in great condition cosmetically, but not bad. Optically and mechanically it is in perfect condition. I should have some fun new pictures soon.
Comparison of Sigma 28mm f/1.8 on left and Sigma 50mm f/2.8 macro on right. The 50mm macro is about the same size and slightly lighter then the 28mm f/1.8
