Most Expensive Lens?

Is this a usual beat-up prewar FED lens or I am missing something? What is Fullrotate?

I have seen no construction differences from all subsequent FED (Industar 10) lenses. I believe "Full rotate" is because the lens turns in its axis when focused- Like Kiev lenses. FED lenses from Industar 26 have parallel focus.

Main difference is changed sequence of distance scale on the lens. If the standart Industar-10 has 1.25m to infinity, full-rotate one starts from 0.5m - infinity. Seems to be usual Fed lens becoming Macro. This is very rare lens, but the price is far away from reality ...

...and only know I came to eBay seller site and noticed that he offering usual Industar-11 lens ... Maybe mistake with photos ...

Below I will place a real photo of full-rotate lens.

Aidas,
I see now. I did not even know such lens existed. And it looks like an easy modification - replace a longer pin with a flat head screw, and put that long pin instead of the short one. It is also interesting that they switch from meters to centimeters.

Yuri,
Such lenses can be found with early Feds only (type 1 or 2).

Regards,
Aidas
