The appearance of a desirable 28mm w/a lens for LTM intrigued me. I lashed out as the asking price was a quarter of the price for an Orion.The lens had been pulled out of a Chaika half frame camera and mine arrived with a tube (?) which was attached to the lens. I put the lens onto a LTM body, set the shutter to "B" and placed a ground glass piece to the film frame and was surprised to see a lovely sharp image on the screen! Russian miracles continue to happen. Well done!

Nice find! Would you mind to measure the thickness of the tube/ring?

It's made for 18x24, so the 69 will vignet, and have a decreasing sharpness at the edges on 36x24 format. But if you can live with the crop factor, it will do.

I'd love one to match the 30's Elmar. I thought the FED 1's had one but have seldom seen one.

On the industar-69, the register is different from LTM. The optics module must be moved in closer to attain infinity focus. It also has a hole in the back that will catch on the finger style RF follower of the FSU RF's. The wheel style RF follower of a Leica will not catch on it.

Yes, I was aware from other articles posted elsewhere of the work needing to be done to get infinity focus. I closer inspection I see aluminium filings around the screw mount, as though someone has already had a go at it. With ground glass to the film plane I get good focus at infinity and, of course, some vignetting, but my pre-war 35mm Elmar did the same thing at f3.5. Wish I still had my Chaika to compare the lenses..anyway for the price, I'm happy!
The tube coming attached to it is just over 2 cm in length. Attaches to 39mm thread.

Thanks!
Thanks!
Oh, the filing! In this case the 2 cm aren't 2 cm...

No, the filing did not take place on the tube. The "pancake lens" screws into the tube for what reason I know not. I developed my film today and surprise! the negs look good. I did shut down to f8 for most shots but did take one at f2.8 but was over-exposed so looked pretty shabby.Vignetting was present but not really bad. I think that this 69-er will become a constant companion. Thats life!

I assume it is an extention tube of some sort. Maybe to get the I-69 to cover more of the film plane on a regular LTM camera? (if the optics work that way at all)
I have not tried my hacked I-69 on a regular LTM yet, but the results with it on my R-D1 are great!
