The flagship GH5 was Panasonic's big reveal of CES (and probably 2017), but the company didn't stop there. Also revealed today is the 4K capable compact GX850 and the 60x superzoom FZ80, both powerful cameras in their own right.
One of the most exciting things about capturing high resolution video with the Panasonic LX100 is the ability to extract high resolution still photos from it. Video grabbing is not a new thing, but in standard definition you were looking at stills measuring a third of a Megapixel, and even in Full HD you'd only enjoy 2 Megapixels. But with 4k video you can make 8 Megapixel grabs which is much more useful.
