This is the Canon EF 16-35mm F/2.8 L II USM lens. It has a constant minimum aperture of f/2.8 all through the zoom range. It has an ultrasonic motor for fast, quiet focusing. This lens is in excellent+ condition. I am the original owner and have treated it well. I used it very lightly over the years I’ve had it. It has never been dropped or subjected to any extremes. It has no dents, dings, cracks or scratches. Everything works very well. The focus, both manual and auto, is smooth and accurate. The zoom ring turns just as smoothly as when it was new. The rubber weather proofing seals are still in excellent shape and do their job keeping the weather elements out. The glass is pristine. I always kept a UV filter over the front, and the surface of the front and rear elements are like new. Internally, there is no fogging or haze. All lens elements are crystal clear. There are a couple of extremely tiny dust bits on some internal surfaces, mostly out toward the edges. These would not have any impact on image quality. The EW-88 lens hood is in very good shape. It still mounts on the lens and does its job. It has no breaks or cracks. However, it does have some wear on it. It has some scuffs and scratches. The front and rear end caps are in excellent condition. The LP 1319 leather pouch (I think it is leather) is in excellent shape. It is clean and has no tears. I am giving the buyer of the lens an 82mm Hoya UV filter. I always kept this on the front as protection. It is in fair shape. It has a couple nicks on the surface. These nicks are very small but could impact image quality when shooting into bright lights or the sun. I never tested this as I most always take the filter off right before shooting anyways. Because of these nicks I am giving you this filter. I put no value on this filter. It is yours to use or throw away. I will not accept returns of the UV filter, or give any credit for it. It is essentially a gift. Also included is the lens manual and original box.
