Nice one, but I bet the photographer wished he had a D800 for that shot. More DR would have helped!
(Obvious flame bait, but it is still true.)
Im not sure you're baiting, it lookes more like trolling. If not, then please provide a serious explanation to your statement. The moment is everything. To capture the moment, a camera with fast AF is essential, having a 5D3 myself, I have to say it's quite adequate when it comes to that.
Also, looking at the charts. 82.9% if I recall it correct couldn't have been taken with a D800 to match a 5D3 on ISO. So again, please proove your point.
I would have brought a D800 and left my 5D at home in case I dropped it in a pool or something... maybe thats what he meant
