Contrary to Travis, I don't commit myself to any system. All cameras have their strong points. Some of their weak points can be worked around, but others not so. I see no advantage in a system. Lens change and better ones come out at even the same focal length for the same camera. Moreover if you are constantly changing lenses during a shoot, then you are probably missing more shots than you are getting. It is also advantageous to take a small cheaper camera into some situations such as night shooting in an unfamiliar city, rock climbing, or shooting from skis.

I go for camera design, features, and ease of use because along with quality lenses that is what gets the shot, not the system.
