Just when Pentax goes 4 k too. LOL
I'm going to use the KP for video at 1080p and 24fps and see how that goes.
Most people don't have the bandwidth to get 4K, or are watching on phones and 720p is more resolution then their eyes can handle on pixels of that small a dot pitch.
The BIGGEST advantage to 4K and above is in the production chain, where 4K ends up being used to send out better quality HD, when compared to filming and editing in HD
For someone like me, who is supplying footage in to other peoples productions, 4K is essential for everything except local news, who want 1080i as the highest level they will accept. Features, Shorts, Doco, Music Video, all want 4K minimum, Sports want higher frame rates.

Originally posted by clackers Rolling shutter is because of how CMOS sensors get their readout. Takes a lot of money to overcome, and global shutters tend to suffer from worse noise and poorer dynamic range, anyway, so I don't want one, thank you!
Sony video's notorious for rolling shutter, even now, and Pentax of course use Sony sensors, and will most likely do so in the new K-3 III:
Sony a6500 Leaves Most a6300 Issues Such As Rolling Shutter Unresolved – DigitalRev Funny thing there is Clackers, handheld Pentax is useable, Sony's isn't - The Pentax and Nikon cameras that use Sony sensors, all have less rolling shutter skew then the Sony cameras do!
And, yes, Global Shutter is more expensive to make, because in needs more memory on the Sensor itself. Noise, is more a function of the colour science being applied - I get pretty Noise Free images out of my Cion when I shoot with enough light, good exposure, and the right Linear to 'choice of favorite gamma curve' Colourspace Transform as my first step in Resolves colour tab.
Another thing about HD vs 4K,.... The camera resolution is not as important as the colour bit depth and colour accuracy, especially when moving to Colour Grading.
My K-01 is 8bit. My Cion's footage recorded on Shogun is 10bit, and the difference in things like Banding in lighting gradients is massive.
The Cion's internal recording is 12-bit, as is it's Raw output, and that leaves most other cameras for dead, because of the extra precision and data available in Post.
A lot of us Cinematographers will repeat the phrase "I don't need more pixels, I want BETTER pixels."
Proof of that, is the continued use of the sub-4K Arri Alexa for Cinema production, while Red, BMD, Canon and Kinefinity push 6K through to 12K resolution.
The push-back is simple - "Red's win Stat sheets, Arri's win Oscars".
(Look up how many 'Best Film' and 'Best Cinematography' wins the Alexa has, compared to Every other digital camera)
