[QUOTE="aroy, post: 199343, member: 16090"] In my opinion if you are able to fill the FX sensor area with object of your interest (in this case the bear), then D800 will score over all the DX format cameras, due to its higher MP. As such the D800 will be as good or better if the crop area contains more than 24MP. It is only when the image is tiny and occupies a small portion of the FX sensor area, that DX cameras offer better utilization.
