This is a beautiful mirror reflex lens with a universal T mount. The mount included is for Nikon F mount (you will need other adapters for other brands).
This one is in good cosmetic condition, but the focus scale seems to be off. Objects that should be in focus at infinity are in focus around 50-100ft. You are still able to find focus, but the scale on the focus ring will not be accurate. The stop points for infinity focus and close focus do not seem to be correct. There is also a small mark behind the front element but it will not affect your image quality on a lens this long. Otherwise the glass is clean and scratch free. The focus is a bit dry but not hard to turn.
The lens caps are included.
This is an as is sale.
