As a Pentaxian (by definition the enemy of some gentlemen here), I'd want Ricoh Imaging to get out their own lenses, as much as possible.

I don't call camera owners, no matter which brand as "enemies". If you need to do so, that's entirely your game. To use your word: "your definition". But that sentence alone leaves me with the impression of a quite narrow minded person on the other side of the screen. It's an impression, not a verdict about you. Not knowing about the current choices of affordable and pretty good performing 150-600 lenses is another thing. Sigma had their reasons to redraw from Pentax. Even they who make some pretty exotic cameras and lenses are kind of tired. It were Pentax bodies I learnt to enjoy the Sigma quality with and that was before the Global Vision concept of Art, Sports and Comtemporary series got started. There were many good features in Pentax bodies, it's a shame their products are no longer seen in normal stores.
