    Are you sure it's actually a lens? Have you tried taking a picture with it? Apr 13 '18 at 10:32
  • I don't know if it is a lens. But has rotating ring, so could be maybe some kind of close-up part, enlarger or similar. I didn't personally try it because I cannot mount it to my equipment.

    What's the diameter of the threads? If it's 44mm, then you're probably looking at a Miranda-compatible part. If it's 42mm, then what is the thread pitch (either 0.75mm (T mount), or 1mm (M42 mount)).

  • There's no doubt that T-mount is from one side. Bigger question is what's from the other?

    looks like the objective of a binocular or telescope

Since it doesn't have any markings I doubt its a lens for any consumer camera. I thought it might have been a DIY type 3D printed lens, but the finish is way better than what I've seen come out of most 3D printers.

My top two guesses

1) Lens for a rifle scope (with some kind of eye pad attached to the other end)

2) lens for night vision binoculars. link
