Peter, the pixel peeping part does play a role, but honestly I am also of the old school that says the only real way to evaluate a camera is to shoot the dang thing until you know it like the back of your hand, pointed at real subjects, and done in real working conditions. If I do that with all the options, then I can honestly say I found the right camera for my particular work. My "test" images are images done for real, not some dang chart full of lines that really doesn't tell me much. Or worse yet, of a brick wall or whatever ridiculous subject that is just about as exciting as watching grass grow. The real world, what you can capture in your own unique vision using a particular tool tells me far more about what I can expect owing the particular monster. Spending this much hard earned cash, I'm for one not betting a red cent on anything but my own very refined senses holding and using the real thing. Sounds like I am not alone in this either, from reading your posts and a couple of the others.
