Nikon 400mm f3.5 AI-S Nikkor*ED lens mount_Pentax K it runs on just regularThe Nikon 400mm f3. 5 AI S Nikkor*ED is a manual focus supertelephoto lens that's less than one stop off the monstrous 400mm f2. 8, and a tiny fraction of the size (and price!) Clean glass, good focusing and diaphragm action. The built in retractable hood has a dent in it, so extracting it is a bit of a chore but this doesn't have any effect on the lens' mechanical or optical performance. Cosmetic condition is good, with some paint and finish wear.
