I didn't realize you couldn't buy Pentax in Utah. That would concern me, too. For what it's worth, we haven't been able to get a high-end Pentax SLR for review since the K10D. It makes you wonder if they're able to produce enough. And I completely understand you wanting to try it on for size before you buy. Personally, I like cameras small. I don't have small hands, either. But I carry them on the bike and skis a lot, so smaller and lighter is better. I think I'm in the minority there, though.

It's a tough call between the Nikon D700 and Canon 5D Mk II. I haven't used the D700, but I'm really impressed with the D5000 and the D90 and I have one pro friend who just switched from Canon to Nikon for the D700. He wanted full frame and good low light performance (they pretty much go hand in hand) but he didn't want huge files and he didn't want to pay for video.

The 5D Mk II is an awesome camera. I really liked it when I reviewed it (my Canon EOS 5D Mark II pro review). But it is a lot of money and you will pay for the pleasure of using it with more storage, slower file transfers and more processing time. That said, image quality and low light performance are excellent. Still, if I had no investment in Canon, I think I'd go with the Nikon. Everyone wants more resolution. But most people don't need 20+ megapixel files. And I sure don't want to deal with them all of the time. The D700 is a more practical choice, I think.

Back to the Pentax now. If you don't have a real investment in Pentax glass and you really want full frame, then by all means, look elsewhere. But I always encourage people to question their motives when they want to switch to full frame. Maybe you've already done this. But ask yourself if you really need full frame, if it's really going to add anything to your photography. If you can't honestly answer yes, then save some money and get a crop sensor camera. As much as I liked the image quality from the 5D Mk II, I don't need it. It's not the difference between making money and not making money for me. For me, smaller and faster is more important. That might not be the case for you. I don't know. But weigh it out carefully and be honest with yourself. I think a lot of people want full frame cameras just because. They've been told they're better and they believe it without really thinking about why. They are better in some ways. But that doesn't mean they're the best way for you to spend your money.

Oh yeah, the K-7 looks like a sweet camera. I want someone to get one just so I can check it out
