I echo Hikari. Additionally, I am more concern about the system behind the camera than the camera itself. I feel that the differences in IQ between between, Nikon, Canon, Olympus, Panasonic, Fuji, et al, is insignificant. I shoot a lot of action so I look at AF/CAF speed and FPS. I shoot a lot of low light, so high ISO noise is important. But most modern, high level cameras, easily tackles fast AF, high FPS and low noise at elevated ISO.... But I am also in a fortunate position. I have had years experience with a variety of camera types and formats. I really don't have to handle a camera before I purchase it. But even when I have the opportunity, it is really not important. It always takes me a few months to come to terms with a new camera. I usually need a project to really know how the camera works. Beyond obvious technical limitations (but AF is not one of them), it is never the camera that could not get the "shot," but the lack of the photographer's skill. I really don't believe a good craftsman blames his tools.
