Well I've been waiting for a while for this to come out, as it is likely to be the camera I upgrade to relatively soon.
Overall, I think it's pretty good. A lot of people have been bashing the fact that it doesn't have weather sealing, which is strange, seeing as it does. But if you're after a 1000 point AF system and 50fps then the 5D was never going to be the camera for you. What were you expecting exactly? The 5D was a FF camera basically all about the image quality rather than anything else. According to the more detailed article on dpreview (
http://www.dpreview.com/news/0809/08091707canon5dmkiipreview.asp) it's basically got the sensor from the 1DsMk3, with a few tweaks. They took this to mean improvements, but even if they don't make any difference, the image quality is still going to be stunning.
I'm not personally bothered about the video, but I can see a lot of people would be, so I do think it's a clever feature.
I shall just have to see how much Mr. Kerso can get it for when I'm looking at changing body ...
