im currently using a canon 40, i mainly shoot action stuff. just wondering if going to the 1dmk2 n would be a step backwards in the way of quality. i recently tried out the new mk4 in nyc and i loved the 1.3 crop factor, 100% view finder and of course the autofocus ability. considering i dont have a lazy 6 thousand hanging around i did some looking around on the net and saw some stellar reviews on the mk2 n. great auto focus sequences at 8.5 fps, the only concern i have is the 8 mgp. im shooting with all L glass so im not sure the drop of 2 mgp will do much... any advice?
