Great thread. I recently decided to pick up a Canon EOS 40D - will be traveling to the galapagos islands next month, and decide now was as good as time as any to jump off the fence and commit
I've always preferred Canon's menu systems, and I think they have a better selection of lenses. Plus I have friends with Canon gear who I can swap lenses with That and the Nikon D300 won't be out until November, and will cost $500 more - the 40D is a no-brainer for a higher end "prosumer" camera.
When I get back and want to start playing indoors - great site on lighting:
I've been spending so much time in the forums on http://www.dpreview.com that I have a pretty severe headache. Talk about drinking from the fire hose!
So now I just have to find one I screwed up and didn't order one Thursday from Ritz online, or I would have had it yesterday. Now I should have it by Thursday.
