I totally disagree with his D4 vs D800 "tests don't matter" rant. I couldn't decide which to get until DxOMark released their results. I'd rather have dynamic range and low light performance and was leaning toward the D4 for that reason. I assumed that one larger pixel would do much better than two smaller pixels on the D800. The DxOMark for the D800 let us know that chopping up one photosite into two (generalizing based on overall resolution) has almost no impact, and if you recombine those sites with software, there's no measurable difference between having one large pixel and two small ones, and so it's a much better idea for me to get the D800 and, when necessary, recombine down to half resolution in software to emulate the D4 almost exactly when conditions require it. That's extremely valuable information for making a decision between the cameras and has nothing to do with "pixel peeking" or being a "gearhead."
