Bill,

second picture that Aidas posted, inside the square opening, I see some kind of round thing in the middle, that seems to me to be some kind of simple lens element....

Hi Vlad,
I see it, but to me it just looks like a round indentation in the metal ... not glass.

Regards, Bill

And maybe you're right.. can't tell for sure unless physically examine the camera... just seemed like a simple lens to me...

Hey people!
The updated page
http://www.photohistory.ru/1207248181000424.html
has now detailed pictures of the Belarus enlarger.This picture:

Although do not mention the detail, clearly shows the front handle of the reproductor in the condenser head.

It looks very much like an oscilloscope camera.

Hey all

Now everything is clear,
One can see that focusing is done with light coming from the enlanger house, passing through the spoked ground glass to the object.
When the sppokes are in focus over the main choosen point, the picture will be correctly focused.
A clever and quick focusing system eliminating needs to see through the camera itself.
As said, the optics are the Industar 58 and others.
So the camera has no lens at all, uses the normal bellows and lens enlarger system.
I will find useful to put such details on Abramov's site.
