My late father had an old slide projector in a leather case. I noticed it had a lens on the end - just an aluminum tube with indents for the focusing screw. Looks like...three elements? There might be more if some are cemented, but it's hard to tell.

I stuck it to an old metal M42-M42 extension tube using Gorilla tape and rubber bands. Road Warrior! Then I screwed it into another such extension tube, then into my M42-FX adapter with a helicoid, then I added a couple more extension tubes on the end so I could proper focus on my X-T2. It now reaches past infinity on the far end, and down to a little less than 1 meter on the near end.

It's very fun to shoot! I did do some post on these shots, so keep that in mind. |

Interesting lens, the bokeh with highlights might not be everyones taste, but you've certainly got some good images from the lens. I like the leaf on the reflective surface a lot. _________________ LENSES & CAMERAS FOR SALE.....
I have loads of stuff that I have to get rid of, if you see me commenting about something I have got and you want one, ask me.

Thanks. It certainly has an unusual character, and it's very sharp. I haven't had a chance to try it for portraits yet, but I'm anxious to try.
The American Optical Company still exists, by the way. They make lenses for eyeglasses. It's an old company, founded in the 19th Century. |

Nice work. I picked up a projector lens at a camera shop a while back for a fiver and it took quite good photos freelensing though with the lens reversed, I never did get around to making a true mount for it. . Ektar 5 inch 3.5 IIRC. _________________ photos are moments frozen in time |

I thought my collection of Projector lenses was excessive.
I'm quite pleased with my 50mm, 85mm & 40mm shift versions, but I've never managed to get the longer ones focused properly - perhaps I'm just getting a bit of droop with the long fittings... |

It looks like a triplet.
What's kind of interesting is that, since there's no aperture and no focus, the elements are sealed in the body. Even though the whole lens was covered in a substantial layer of slightly-grimy dust when I found it, there's not a speck inside. After a good cleaning the glass is as clear as any lens I've ever seen. |
