Sella - So you say dual pixel tech in liveview shooting is "Useless to a stills-only photographer like me."
Then why are you even the least bit concerned about the development of 4k?
BTW, not sure if anyone filled you in, but mirrorless = liveview shooting. I think that makes dual pixel a little bit significant at least, wouldn't you say?
John, be careful.... you are using logic... this is an emotional argument and things like logic and common sense have no place
What seems to be missing from the argument/discussion is 4K video
A year ago GoPro comes out with 4K video at 15 frames per second.... not fast enough to be useful for anything other than landscape shots.
Now Panasonic comes out with 4K video at 24 frames per second... still not fast enough to do anything beyond very slow moving objects
The next step will be
?? with 4K video at 30 frames per second... fast enough to shoot people walking and only have minor jerkiness. It would also be fast enough to support 2K video at 120hz
4K will be here when someone offers 4K video at 60 frames per second and motion starts to get smooth. This will be the camera that supports 2K video at 240hz to really capture fast moving objects.
The bottleneck is not sensors or cpus, the bottleneck is writing to storage. When that problem is solved, the dominoes will fall. When you see a camera with CFast or some other fast (or faster) storage, then and only then will you see 4K video at reasonable frame rates.
