This is a used but never abused Nikon 17-35 2.8 lend.  This one has been my favorite for many years as I started in digital with crop-bodies.  The 1.5 conversion makes this view like a 25.5-52.5  The glass and body are in nice shape but the autofocus motor has gone out.  Ive been using it like this with no problems shooting in manual focus.  A great deal on a beautiful lens. B&H has this lens new on their site for almost $2000 so getting it fixed would be worth it to the right person.
