According to DxOMark the dynamic range of the Nikon D800 is a whopping 14.4 stops. I have no problem believing that it is not the same as the Alexa and that the Alexa's 14 stops are calculated differently. It is interesting though that the Canon 5D Mark III only scores a mere 11.7 in the same test, making it almost a half stop less than the 6D (currently the best performing Canon DSLR in the dynamic range category) and 0.2 stops lower than the Mark II Nikon D800: http://www.dxomark.com/Cameras/Nikon/D800 Canon 5D Mark III http://www.dxomark.com/Cameras/Canon/EOS-5D-Mark-III Does anybody else find this a bit peculiar? Especially since the 5D is the "go to" DSLR for filmmakers, heck I even own one my self.

Hi i am wondering about buying a GH3 it will be used for landscape/nature footage but i am uncertain about how much better the GH3 dynamic range in video mode is? I know that the GH3 is superior in photo mode but how much better is it's dynamic range in video? The GH3 and a decent lens is a large investment and i want to know that there will be a big different.   I want a smooth organic image quality. I have seen alot of sample footage and yes the GH3 is much sharper and certainly superior bitrate compared to the RX100. But i am more uncertain about the dynamic range.   Would be nice if maybe someone can make a dynamic range comparison between the RX100 and the GH3. With the best possible settings on both cameras.   I own a RX100 which is certainly a great camera. The GH3 is interesting but i have not been convinced yet that it will be worth the cost.   Dynamic range is very important but i can't afford the cost of the BMC with lenses and accesories.   I would really wish for a camera of the size of the RX100 which would have the dynamic range of the BMC in it's video mode. I hope it will happen some day.   I have also been looking at the canon HF G20 and G25 cameras but am disappointed that they still are 1080i based cameras. The panasonic SD900/X900/X920 have even smaller active sensor size then the G20/G25 so they are out of the question. I have the SD600 (which is 3xcmos and 1080p 50fps) and the dynamic range certainly is limited and kills all chances of the organic quality i want to see.
