Sigma labels its current 28mm f/1.8 lens as a macro lens as well, but it only focuses down to a 1:2.9 magnification ratio. By way of comparison, Nikon's current 28mm f/1.8 reaches 1:4.5 and Canon's only 1:5.2. I've found mine is useful when photographing necklaces and beadwork on a copystand, but I feel calling the Sigma a "macro" lens has more to do with marketing than capabilities.
