Hi, I have not committed to any brands of cameras yet, but would be soon. So here's the question. What is the general characteristics of the different digital systems(nikon, alpha, canon, 4/3)? I know the 4/3 zuiko have nice colours, but does that mean canon and nikon lens do not? I know it is hard to generalise as it depends on the different lens. but is it possible to draw any general characteristics of the different camera systems?
