This is the classic 105mm f2.5 AI-s, one of the best lenses that Nikon ever made. It is a lens that every classic Nikon users needs in the bag. This is the latest and best version and has a built in lens hood and improved coating.
This lens is in good condition and works perfectly. The focus is smooth. There are a few small cleaning marks on the rear element and a small spot of coating wear on the front element but neither will affect your image quality. Otherwise the glass is clean and scratch-free.
