Manual focus only! AF does not operate! VR works great. Glass is really nice. Very clean and clear inside. No scratches. Zoom turns smoothly. MF turns smoothly. Includes Nikon soft lens cap and L37c filter. It is possible to use 2" astro filters with this lens by modifying the thickness of a 52mm to 48mm step down ring. I used this lens with the Optolong L-eExtreme and a D810a in order to get the last image of the Heart & Soul Nebulae. Pretty good deal for a fast f/4 scope with incredible glass and adjustable focal length. Please no low-ball offers I would rather keep this as a travel scope than let it go for nothing.
