We need more pixels!! G10 vs P45
The high-megapixel advocates seem to be dominating the 5D MK III discussion.
But if the IQ of this camera turns out to be really striking (Canon's official samples are always questionable), and the problems of 5Ds past have been eliminated, the feature set of this camera, and the balance among them, may have achieved a critical mass for its class that could set the standard for some time to come. Perfection at last? Perhaps not, but getting pretty close.
