Mechanical operation is normal with smooth focusing, easy, positive aperture ring action, and clean, snappy diaphragm movement. Glass elements do not have any optically significant blemishes; there is the usual trace haze seen in all of these lenses from this era (this is what un-informed sellers call "light dust").This is not apparent to the un-aided eye, but can be appreciated with a strong LED pen-light. Lens comes with appropriate Nikkor front cap, and a later Nikon LF-1 rear cap. Remember, this is a vintage lens intended for use on Nikon F bodies, and other PRE-1977 Nikon film cameras like the Nikon F2, Nikon F2S and Nikon F2SB (and pre-1977 Nikkormat series bodies). (Also, because of the large surround on the rear of this lens, it cannot be mounted on the Nikon F4, FA and FG). Returnable only if not as described.
