This is the classic 10.5cm f2.5, 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 Photomic (non-AI mount) and works only on older F, F2 and Nikkormats. It does not work on any digital without modification or an adapter (except the DF). What is "Nikkor-P?". "P" is for "pent" and means five elements. The lens is in excellent condition and works perfectly. The glass is clean with no haze or fungus. There are some very slight cleaning marks on the rear element which should not affect image quality. It comes with caps.
