I would think it best to restrict something like this to lenses that can be used without an adapter. It might be worthwhile to include m42 Pentax lenses, but I would draw the line there. BTW, although you can fit a Leica 39mm screwmount lens to a Pentax with adapters, it won't focus anywhere close to infinity. It will be macro only. Not exactly useful.
