Lens MP RSFSR GLAVUCHTEHPROM Plant No. 6 F = 7,7cm
In fact, this is not a review of the lens, since there is nothing to see :). This strange instance of the MP RSFSR GLAVUCHTEHPROM Plant No. 6 F = 7,7cm is a lens from a filmoscope.

Here is the enlightenment of the front lens
The lens came to me without an additional tube with a wormhole for focusing, because my lens does not have the ability to focus at all. Also, the lens has neither a threaded nor a bayonet mount and there is no aperture device. I connected MP RSFSR GLAVUCHTEHPROM Plant No. 6 F = 7,7cm using a macro ring for M42 optics. I connected the ring to the lens using adhesive tape (adhesive tape), and using the M42-Canon EOS adapter, I installed the lens on the camera Canon 350D.

Rear Lens View
The lens is easy to disassemble. In the middle of the tube are two lenses and a thin separator tube.

Disassembled
This is how the modified 'lens' looks on the camera.

Radojuva L lens :) I just did a wrap in order to hide the layers of adhesive tape between the macro ring and the lens.
Sample Photos
You can, of course, make fun of the photos a little and pass them off as'Masterpieces','psychedelic' or 'vintage', but it's best not to do that.

Conclusions:
When photographing, the lens does not give any high-quality image at all. Perhaps someone will like the bokeh of the lens and the intentionally low quality of the image, which may interest an unusual picture :).

Something even wanted to indulge in such a "periscope")

It is really easy to "indulge" with him. Sorry, I inserted it into a cardboard tube while preserving the possibility of movement - and focus on Nikon at infinity :-))) True, I had to whip off a bit of excess plastic from the tail so that it would not cling to the mirror.
Chromatite is yes, well, it's a periscope ... The thing, of course, is not for every occasion, but sometimes it is suitable.
GLAVUCHTEHPROM 136mm has recently been adapted. It has a large back section (to prevent the lenses from melting). The periscope gives an interesting picture. I really liked it. Especially interesting in the play of shadows and contrast of a still life or landscape.
How did you adapt it?
