Hmm... This is interesting. Thanks for the update, rei. I think many Pentaxians are dying to see a full frame camera, so I'll be intrigued to see if they deliver, of if it gets delayed again and again like the DA* 60-250mm was.
Shame about the teleconverter, as I could really make use of one.
Any word on lenses? Pentax fails at having a longer, affordable telephoto, like Canon's 100-400mm L lens or Nikon's 80-400mm. This frustrates me greatly, as I want a sharp, fast tele lens that will actually get me some reach... and Pentax has nothing there.
