4k kills the photography business? The Canon EOS 1D C shooting stills !

Video recordings are usually 8 bit, lots of compression and further colour sub sampled than Bayer raws.  The slow shutter speed is a good point too. So not in the same league as raws for high end work.

Here's a camera that shoots DNG raw to a SSD at video frame rates but it's M43,  $2995 with a

grading program -
