Canon 100 - 400mm L f4.5-5.6 IS USM telephoto lens and case. I've owned this lens for about four years and bought it used. It is the original model of this lens NOT the MK ll newer one. It is great for birding, sports etc. and with a 1.4 extender on it reaches out to 560mm making it a great telephoto lens for a relatively low price. The tripod collar is attached but removable and a new lens shade is on order. If it doesn't arrive before the lens sells I will make sure the new owner gets it. This lens will fit any canon lens that accepts interchangeable lenses. and on a APS-C of a 4/3rd camera with an adapter makes it a real long lens
