Lens adapter for M

I made up my mind to use Minolta MD Rokkor 28mm/2 SLR lens on Leica M9 digital body, of course I know there exists a critical problem, focusing coupler to be combined with body roller cum mechanical construction in range finder.
Because of wider view angle almost twice as standard lens's focal length, closing the iris to f-5,6 enough to obtain to be focused from 5m to infinity, so no focusing operation is necessary. This is why I apply Minolta MD Rokkor 28mm/2 on range finder focusing Leica M9 digital body without focusing coupling. This excellent MD Rokkor would wake up from 10 years period of time hibernation.
