Hey guys, thanks for all the replies. Too many to answer individually, but...
I have a P&S now. I've used a friends Rebel XT (or maybe XTi, can't remember now) a few years ago, and I still have an old Minolta 35mm SLR that I used to use many years ago. No, I have no Nikon or Pentax lenses. Oh yeah, and the camera on my iPhone.
I mostly shoot travel photos (indoor and outdoor portraits - of people and of "things" such as statues, food, street scenes, etc. as well as some landscapes), nature, and fine-art style photos, but I've also tried some sports (Rugby) shooting (yeah, with the P&S - needless to say that didn't quite work out), and some "action" photos involving mountain bikes and motorcycles. I guess I'm kind of all over the place. I'd like to do more outdoor stuff, including some action-type stuff. I'm leaning towards the magnesium bodies for duribility outdoors, and the K-7 does apeal due to its size. I think if I didn't want the WR body, I'd also be looking at the D90.
One thing that sucks, there are no stores anywhere around me that carry Pentax. So I have to rely solely on the intertube. I have played with the Canons and Nikons though (in the store).
Now for the intangable...
I too get the idea that the K-7 (and Pentax cameras in general) kind of have a "cult" thing going on - not David Koresh cult, more like Rockey Horror Picture Show cult.
I like it - you can really "feel" a difference between this forum and the major Canon and Nikon forums. I guess that's something else in favor of the K-7 that isn't in any review. From the "vibes" I get, I think I'd feel more "creative" with a Pentax, as opposed to more "serious" with a Canon or Nikon. Or maybe there's just something in the water here.
