Thanks for that information, it's reassuring to know. I'm sure I read somewhere that the Sigma 300/4 APO is recognised as FA 300/4.5 which is close, I'm wondering if the Sigma EX 70-200 will be recognised as FA 80- 200/2.8? that would be close enough for me. It's worth remembering the Tamron/Pentax colaboration for future reference.
