I have never been able to focus sharply with this lens. Tried a few days. It was refurbished by Nikon themselves so I thought it was like new. My d5600 doesn't have fine autofocus in the camera, so I couldn't compensate for the front or rear focus shift of the lens and had to reset it. I ended up buying a brand new Tamron lens which focuses great for a few bucks less (on Tamron and Sigma lenses you can adjust the focus on the lens itself with a USB adapter).
