Sigma Contemporary series 16mm f/1.4 wide angle lens with caps and lens hood for Canon M mount. It's roughly the equivalent of a 24mm lens on a 35mm camera. The lens has been tested and it works correctly. The glass is clear with no fungus or haze. The lens hood is cracked on one of the petals but could easily be glued with some super glue or epoxy. The lens is clean cosmetically showing very little if any wear
