Sure, I can tell you more in a while.


Good day Jacques,
yes on some occasions you need to be quick before the rest of the wolves smell the meat. At least this Fed wasn't expensive. I thought that I won't use this occasion and give the luck to the next fastest collector. Happy it was you.

Yes Jacques, all these cameras take a lot of time. At the moment I'm trying to remove some black shoe polish from the vulcanite. I hate shoe polish on a camera.

Do you think your viewfinder looks like factory made?
I don't have a clue what it can be.
Thanks for your photos.

It must have held some small flip up and down mirror to peak through the lens. For microscope use perhaps?

I agree, there is nothing better than pure undyed beeswax to conserve leather and vulcanite.

No, I don't think the modification was made by the factory. But certainly it was made professionaly. Probably for a technical use: microscope, telescope or other.

It seems the inside has been repainted in black after the work. As for the date of the modification, impossible to say. The seller knows nothing.

Of course, this camera is not the first reflex. But it is the first NKVD reflex. Sure! And it is one of the first S (without lens).
I will dismount it tomorrow.

Amitiés. Jacques.

I am surprised by all this tiny work, really well made.
Impossible to imagine it could have been made on the corner of a table...
Certainly the cost was high, so the utility of this modification was probably important.

Really I wonder what it was used for... Industry? Laboratory?
All ideas are welcome!

Amitiés. Jacques.

Thousands of thanks for your schemes, Luiz. Fascinating!

So,with this Fed, there were two lines of sight:
- one through the extra finder, via the prism and the frosted glass,
- the other through the usual viewfinder.

There is not much room inside the chamber, so, the mirror had to be small. Anyway, there is a trace of its rotating axle, towards the rear of the "periscope" (my photo posted at 11.27.23)

All that was certainly not very easy to use. This camera was made in 1938 (perhaps 37) and the SLR had officially appeared two years before with Exaktas and GOMZ Sports which were probably expensive and difficult to find. So, a very special work for this camera? A prototype? Made before WW2? And with which lens?

Thanks for the link towards the Zorki 4 periscope, Vlad. I remember having seen it at Alain's. What a mess to mount and dismount it!

Amitiés. Jacques.

this interesting system of course have to há a very small mirros aiming the center of the lens. In Ucaflex I saw a very slight "V" in the moving mirror mount
That way all the system can be contained in the small lens register of FED câmeras.
A beter solution was made in Periflex câmeras where a fumm rigid periscope comes up and down.
This system does not deregulate in full camera's life and no matter in which position it will stand.

Anothes extraordinary solutin was built in French Focaflex prototype where the screen is a cylindrical frosted mirror in the bottom! having a semi transparent fixed mirror! -current production boasts moving mirror!

Many Focaflex(es)work no more, alas.
It was a very clever system, but fragile. And Foca was no more at its best in these years: it was too late.
Thanks for this beautiful scheme, Luiz.

About my NKVD "reflex", I wonder about the mirror.
The axle of the periscope is not exactly centered. So, if I understand how all that could mechanically work, I am not sure of the optical work. Certainly several parts are missing.

All that just to discuss. As we don't know what was the use of the camera, it's difficult to imagine how it worked.

Amitiés. Jacques.
