Yes, I have an MD-PK adapter with glass, and have used it for several of the vintage Minolta lenses, several different 135mm lenses plus the Vivitar 28mm f 2.8 in Minolta mount and the Minolta MD Zoom Rokkor 35-70mm f 3.5, which has been said to be in some way related to Leica's 35-70mm vario-Elmar-R f 4.0 lens. Adapters containing glass seem generally to be spoken of disparagingly on Pentax Forum, and I am not enough of a pixil peeker to refute any criticisms that have been made. However, I will state that i have obtained very satisfactory image quality using my Minolta lenses with the adapter on K-1 and K-3 cameras. How much better the images could have been on different cameras not using a glass adapter, of course, is not known to me. The general reaction seems to be that adapters containing glass are not worth trying, but my personal experience is that perfectly good images may be obtained using them. I would never invest in a whole line of lenses to use with a glassed adapter, but see no problem using such an adapter on an episodic basis.
