Instant purchase welcome. This is a wide-angle conversion lens that is almost unused. It appears to have been used very little, and both the exterior and optics are in good condition. It can be attached directly to lenses with a 55mm filter thread, but the included ring allows it to be used with 52mm lenses as well. Included accessories are front and rear caps, a case, and a 52-55mm step-up ring. #Canon #ConversionLens #Wide
