Only used a handful of times, it was part of a backup system that was rarely needed. Condition pristine and unmarked. The lens has good overall sharpness, ultra-wide coverage and has dust and moisture resistant design. Fluorine front coating. Focuses down to 9.4 inches, (good for close ups with blurred backgrounds when used at 3.5mm) It features a VR on/off switch plus a AF/MF on/off switch on the lens barrel, as well as a reversible lens hood. This lens is well suited to the Nikon D500 or D7500 or similar. It includes excellent optical stabilization (VR) for stills and video capture.
