The Nikon 45mm f2.8P Nikkor lens was released along with the Nikon FM3A, but it'll fit any Nikon F mount camera. It's also super tiny- a true pancake lens, extending less than 2cm from the lensmount. Excellent image quality, too. And while this is a manual-focus, lens, the P chip provides full metering and focus confirm capability with nearly any Nikon F-mount camera. These were produced in limited quantities, because sometimes Nikon doesn't make the best possible decisions. This one's in really nice shape, in near-new cosmetic condition with clean glass. It includes its original front and rear caps, soft pouch, plus the HN-35 hood.
