Selling a like new Canon 50mm 2.5 macro lens. This lens is perfect, the glass is clean, the autofocus is accurate, etc. It can work either as a fantastic macro lens, or as a small, fast prime. Built waaaaaay better (distance scale, metal mount, better quality glass) than the 50mm f1.8 for not much more money. This lens will work on ALL Canon digital DSLR cameras (full frame or crop), as well as any Canon film SLR made after 1987.
