I've been going over some lengthy reviews about the K10D, and it seems to be an amazing camera. 10MP, image stabalization, weather-sealed, etc. The only real flaw I can see that would deter me from purchasing it is the lack of a dedicated iso and wb button. It isn't quite buried in the menu, but there is a button (fn) that, when pressed, allows the user to change either the iso, wb, flash, or drive mode. Am I going to long for a wb button, or even an iso button? Also, are Pentax lenses comparable to Nikkor or Canon? I don't plan on spending too much in the near future on lenses, but I don't want to buy into a system inferior to the big two's. Last, is Pentax a generally respected brand? I don't have too much time invested into the world of photography, so I don't have the same common knowledge as many of you do.
