Frank, I had the same problem with a newly bought Kiron 105/2.8 PK (not PKA) macro lens that I bought in 1999 or 2000. I sent it back for repair. The spring had come out of place.

Putting it on a body doesn't work. Has this ever happened to anybody? Anyone know if it can be a quick fix? I'm hoping that some little spring inside is just out of whack or broken or something.
