This is a like new 70-200mm f4 L IS II USM lens. This is one of Canon's best and most popular lenses. This is the Image Stabilized (IS) Mk II verson, with improved design and weather proofing. This lens the better turn barrel zoom design, where the lens does not extend. It's all done internal. Very nice. This basically a NEW unused lens. I have original box and everything that came with it. I doubt 50 photos have been taken with it. Not a mark on the lens. It's mint condition. Careful: Apples and Oranges there are a lot of non IS, non mk ii, being sold. * this lens retails for $1200+ * a non mk ii, is about $900 * a non IS is about $599 The IS, mk ii is the newest model, and best lens of the many versions in the 70-200mm range. Includes end caps, lens bag, papers, and original box. You will not find nicer, at this price, in this condition. I will not reply to lower offers. Dont waste your time.
