I've owned this lens for two years and it's fantastic. I'm selling all my lenses and due as I'm upgrading to a full frame Sony. This lens is in  perfect working condition, with no blemish whatsoever on the optics. There is a very thin, very minor cosmetic scratch near the "Zeiss" logo, that is barely visible in one of the photos here and a little more visible in person. There is some minor abrasion on the grip grooving that is also very minor, visible in the photos. I took great care of this lens and it will produce wonderful images for the buyer.
