Please ....Please post Raw files at ISO 800 1600 3200 6400.
actually make that ISO100. It's hard to judge much from random shots but a few things like DR can be measured and Canon already does fine there at the high isos. An ISO100 RAW file would be awesome. Any subject is fine, although a pure black frame (body cap on, dark room, 1/8000th, ISO100) is best. Just curious if they put some special new tech in the 1DX sensor compared to the 5D3 and older sensors and if it has say D4-like DR or not (I'm not expecting it to be able to match D800 DR).
Anyway, have fun!
