By all means get a 5D mark III and load the 1.1.3 firmware on it. Then download the crop_rec_4k experimental build. Make sure to use a big, fast and reliable CF card like the SanDisk 256GB Extreme Pro. I'd also suggest getting a big fast SD card too so you can simultaneously record H.264 proxy video on the SD card while recording raw video to the CF card.
