Nikon 400mm f5.6 AI Nikkor*ED back Requires one 9v batteryThe Nikon 400mm f5. 6 AI Nikkor*ED is a well made telephoto lens with a pretty reasonable f5. 6 aperture. It's not exactly a lightweight, but it handles well, with a big manual focus ring for easy handheld shooting, and a rotating tripod mount for when your arms get tired. In excellent condition, with minor cosmetic wear, most notably a shallow ding in the extendable hood. Clean glass, good function.
