Industar-13 , 4,5/300mm M39 SLR

[Drack]

Hello,

I was searching through ebay for some rare collectable items and found a very strange lens up for sale.
http://www.ebay.com/itm/industar-13-4-5-300-SLR-m39-lens-zenit-RARE-/190531520808?pt=Camera_Lenses&hash=item2c5c904928

Has anyone heard about this lens? Any experience? To me personally it looks like a lens which was originally used on some sort of military/aerial camera of some sort but not a simple SLR like Zenit C.

Looks like it's a medium format-lens with the M39-part placed behind it just like what happened a lot with the Meyer Orestegor 300mm f/4.

It looks like a large format barrel lens adapted, rather skilfully, to the SLR mount. Thats my guess anyway.

This thing is most likely unique.

This wasn't made by an amateur because cutting a helical screw, as appears to have been done here, is not all that simple.
On the other hand no lens design shop intending something for mass distribution would have made such a clunky thing.

There was a line of 300mm/4.5 large format lenses - http://www.mattdentonphoto.com/cameras/industar-37.html

A slightly earlier version I think was the Industar-13 also 300mm f/4.5
There are several references on the net.

These would have been intended for 8x10" format (or 18x24cm European format)

There was an Industar 4.5/300 made for the Photosniper, but this one doesn't appear to have any attachments for the riflestock.

It is the lens of Tessar origin. Generally it had been used like the portrait lens upon large format wooden cameras FK 18х24sm.




However also had been used for the aero photography NAFA-13, AFA-13, AFA-1, AFA-B.
It is not very common, however also not very rare.

For 24x36 it has too weak resolving power. However at the time of 70-th there had been the greatest lack of any tele lenses in the USSR. So, the desperate photo amateurs were using any kind. Especially if it happened “to borrow” anything like this lens from the government storages (this kind had not been presupposed to be sold to the private hands). And it had not been very difficult to find the worker on the government factory, who would do for you the helicoids of any complicated structure, sometime even for the bottle of vodka.
