The new Panasonic 4K HC-X1000 is just arriving on our shores and HD Warrior will receive one of the first production models to review.
The HC-X1000 is a 4K camcorder supporting various recording formats, like 4K/Cinema 4K/Full-HD, frame rates including 60p/50p/24p and a host of professional functions.
4K 50p is a spectacular achievement for a camcorder running onto SDXC cards. (Class 10 speed 3). It will be interesting to see how much time you get onto a 64G card.
UPDATE : The camera records 4K at 150MB/s therefore a 64G card will record 40 minutes.
