4K is the big buzz phrase this year. Camera-wise though, the selection is still a bit slim. Sony showed off its new FDR-AX100 and Panasonic featured a prototype 4K Lumix camera. Additionally, JVC had its 4K version of the PX100 on display as a reference exhibit at CES 2014. The camera was tethered to a 4K display and streaming 4K footage from its HDMI port.
