I respect Pentax call on not making video a big priority. They don't have the expertise in house, and making excellent stills is their strong suit.
But Lumix gear is now getting adventurous with 4k video in very creative ways:
- your 'basic' 4k UHD video
- pulling 8Mpx stills from fast-video settings (using video as super-burst still cam)
- new video/burst mode: AF focuses briefly on everything - you pull your choice of focus later
Yes these are 'only' 8Mpx shots - but you are pretty much guaranteed the shot you wanted. The 4k/photo can use fast shutter speeds to freeze action, and of course IS inside of nearly all Lumix lenses. That new all-focus 4k is a firmware update. And when you can take your time the 16Mpx 4/3 sensor isn't bad either.
For the current sale prices I'm picking up a G7.
It won't replace my K-50 but it will do things I don't expect to see from Pentax any time soon. They could kidnap an engineer and start a video lab tomorrow of course, but I sorta doubt it.
