The pictures below are already cropped in a 4: 3 aspect ratio. When open, the lens has low contrast and, moreover, is not very sharp. During the test, I could not even resist and, contrary to usual, closed the diaphragm a couple of times (the difference, I think, will be noticeable even without the caption under the photo).
Mir-11M color produces natural, but smoothed. On closing diaphragm forms an "asterisk", but it is almost impossible to notice this in the frame.

Joining Mir-11M to any adapter for a mirrorless camera is very laborious and does not cost either time or money. Yes, the pictures taken show that it behaves like a classic wide-angle lens, but does not have any outstanding performance in relation to the camera.
