For those that don't read the fred miranda forums as soon as these images were posted they decided most of them were crap. Not because of the hardware--though they weren't big fans of the 600/800mm lenses--but because they thought there were tons of photographer errors. To the point that they wondered if Canon specifically hired people to take the worst photos possible for samples.
Just curious what the CR crowd evaluation is.
When I saw them I felt like they could have been taken by any modern camera and any decent photographer.....so Canon does not hire world class photographers to shoot their sample footage...IMO it does not matter, few people are world class photographers anyway. I just enjoyed the pictures for what they were...nice pictures. All modern cameras are within a few degrees of each other and being in the right place at the right time to capture a moment that will never occur again is way more important than pixel peeping specs; it is just pictures, people take this stuff way too seriously sometimes.
To me the ecosystem, and supporting features such as redundant card slots, ergonomics, menu system, etc is way more important than the DR and ISO performance. No client is going to care what your camera's DR or ISO performance is...they will care if you miss a shot due to ergonomics or lose their footage because your memory card got corrupted.
