Leo from this forum sent me his filter for K110d to me. Dimensions are 28mmX22mmX 1.6mm.

I do not know if K100d uses the same size filter but this should get you started.

Some links to glass mfg. I think they call the clear glass windows.

Thanks I just wonder if the K100D would be different because of the Anti shake, though I doubt Pentax would go though that much in manufacturing.

Thanks for the links too!!!
