[4K] Panasonic HC-WX970M vs Sony FDR-AX100 Shoot out

The latest 4K camcorder from Panasonic went on to sale from January 22nd, 2015, against Sony&originator of this genre. WX970M is so small you&think you can put it in your pocket. Literary this is the smallest 4K camcorder available in the market at this moment. There is downside though. Notably, stretched 20x optic system is the weakest link especially in tele-end and small CMOS(less than half compare with AX100&1 inch CMOS) generate more noise and less resolution. Still, this is well composed camera to seek best balance of compromise and this will be my first choice for sight seeing travel to overseas. 64GB internal memory is the bonus. Raynox x0.66 wide conversion lens was disappointing.
