But a new 6 or 5 body? Really should have it.
no problem, really easy: Canon just should offer 2 versions ...
A) "regular" stills-optimized 5D IV with 50 MP and no video out or HD-video at best @ 2999
B) a video-capable 5D IVs with 24 MP and internal 4k video capture (but not raw 4k out) @ 3,499 ... would be still competitive compared to 12 MP Sony A7s which requires use of an external recorder to capture 4k video [at significant additional cost]. Thanks to much larger 5D body internal 4k capture and heat dissipation should be no major issue.
I'd really like to see sales statistics then.
I do not know, but my guess is, that Sony sales of A7s are max. 10% of combined A7 / R / II units.
Yes. My only point was Canon needs SOMETHING with competitive 4k that isn't $10,000. I don't see why they can't/won't make something competitive with the Sony and Panasonic offerings when Canon itself was the DSLR video pioneer. I don't expect RAW output for $3-4k. But a real clean 8-10bit HDMI out would be lovely and on par with the competition. Add in Canon's superior color reproduction and the EF lens system... Look at all the effort they put into the 7D2 video AF system.
Untill the 1080p snapshot has the resolution and quality of a 1080x1920 pix still; why are we asking for 4k when we know it will be a mush anyway?
