Are Pentax filter bayonet?

greenspun.com : LUSENET : Pentax 67 SLR : One Thread

I am looking into purchasing a 77mm circular polarizer, and I noticed that Pentax sells one. I intend to use it with both with my 35mm SLR and with my soon to be acquired) Pentax 67. My question is, does the Pentax 77mm circular polarizer have threads or a bayonet mount at the lens side?

Also, is the Pentax 77mm circular polarizer SMC-multicoated?

Thanks,
