Pentax DSLR : Transform M Lens Into FA Lens

I have done this transformation about 6 months ago. For this transformation, I used Phenix 50.7 lens and FA28-80 lens. I have changed the Phenix 50.7 mount with the FA mount. Sorry I dont snap a picture during the process to show you.

Here is how the final image look like:

And here aare some test result at various aperture. Aperture was changed via body setting.
