Minolta MD to... whatever modern mount - possible solution?

Hello there,

While playing with my Minolta MD lens on my Pentax K20D, I had an idea. Since the problem with the lens is that you can't go far enough to actually get infinity, I reflected, thinking about my experience with Russian lenses, that a theoretical solution solution could simply be to go past the normal infinity point and get to the actual infinity?

I haven't dismentled any of my Minolta lenses for that (but since I have three 50/1.7, why not sacrifice one) but I wanted to know if you thought there could be a possible limitation to that?
It would be way easier than resorting to plastic surgery, machine tools and 1.36453638mm shimming?

Well, the Digitalrokkor seems to be one solution, but it is a bit of a surgery.
When you focus a lens you basically operate an helicoid inside the lens. When the lens is properly adjusted at infinity, a screw or whatever part prevents you from going past the infinity point. However, that infinity point is calibrated according to the focal flange. By moving the infinity point one may achieve a proper focusing...
