Canon 40D. More importantly, I try and use good glass. The first photo was taken with a 10-22 EFS lens. It's not an "L" lens but the quality is considered as such. The bear photo was taken with a 70-200 f2.8 L IS lens. The camera doesn't matter. A cheap Rebel could take just as good of photos. I'm a big believer in glass, not the light capturing devise.
