Specifically, what lens IS it? Make, style, etc., etc. M-42 or K-mount?
Did you have it set on Manual or Auto when you tried this?
Etc.

EXxample: I took an SMC Takumar 1.4/50mm, set the lever on Auto, and
wound the aperture ring. Nothing at all happened to the aperture blades.
They stayed wide open. Like they should have.
If I put it on Manual and rotate the aperture ring, the blades open and
close...like they should.

Is that what you're experiencing?
