Adapting SMENA 8M lens to NIKON F

As previously stated, I tried to adapt SMENA 8M 40mm, f/4.0 lens to some DSLR. After week with no camera at all today I got my almost brand new NIKON D70s with only 1k pictures taken. I took NIKON F mount ring from some broken SOLIGOR lens and glued it to SMENA lens.

Of course because of registration plane (flange) distance I cannot get proper focus but still can do some tests, which you can find below.

I find it pretty good looking. In order to get out of some 30cm area I would need to have entirely different camera system, such as mirrorless. As for now I do not own such.
