Its video is 2540 or some such, its not 4k video as I understand it so, why bother? You can't project it except with a very special projector. Downsample it to 1080p I guess.
13 stops, yea who is counting the dynamic range? This from DXO?
Yup, stick with a DSLR/mirrorless for video.
4k video comes down to Cameras in general, I will grab one. Always thought 1080p was way too little. Anyone doing a slid show all know this when one projects this content onto a screen for showing pictures/video. In this respect, film is still superior to digital, though with 4k video even this aspect will disappear finally, or at least be negated severely.
I can't wait for affordable 4k video... That and if someone will finally start selling us LCD/Plasma screen for computers/TV that will have this resolution. Technology exists. That danged uesless 16:9 ratio that everyone is selling now coupled with 1080p ug... We can still keep 16:9 ratio if the pixel count of screens goes to 4k instead of 1080p like it is today allowing document shrinking since we would then have enough pixels.
