You will remember a while back the discussion of the new Pentax copyright for a lens mount / sealing rings?

I suspect the DA and DFA, which have two different types of rubber 'O' ring, one called WR, the other not mentioned, will both be accommodated in the new camera. I'm not going to look, but I don't know if any of the FA and older lenses have any 'O' ring at all. The newest lenses will have more of an 'O' skirt, if my memory serves.

Does this include 3rd party Sigma, Tamron PKAF fitting? I own 2 Tamrons and 4 Sigmas, and I'm thinking of getting the newly released Sigma 120-400 APO HSM.

Subject: How many DA/DFA lenses do you own?

You will bitch against older lenses (FA and older)... ;)
Well, at least those upgrading to K-7 (no, it's not compatibility
related, don't worry).
Simply, that feature is DA/DFA only.
