My wife and I were in the Smoky Mountains this past weekend and my FIL was kind enough to let us borrow his Nikon D80 and 18-105 4.0 lens.
I looked up the stats of the camera and found that it wasn't that different from my Rebel XS and yet I was consistently disappointed with A-B comparisons between my Rebel XS w 18-55 kit lens and his Nikon. My images were frequently blurry, or not entirely in focus while the Nikon's images were almost always crystal sharp. My one beef with the Nikon is that is drastically overexposed face portrait pictures.
Am I crazy? Is something wrong with my camera? I know his lens is nicer than mine but I wouldn't expect that to have anything to do with focus or sharpness because that's a calculated value from the camera body.
I've been thinking of upgrading to a T4i but after this weekend, I'm questioning whether I should be using a Canon at all.
