If you've been considering the Panasonic GH4 camera, today most retailers have discounted -$200 OFF. This camera has a battery that can run for hours and hours, 4K video direct to SD Cards, and a variable frame rate of up to 96fps at 1080p. The HDMI can output 10bit in both 1080p and 4K if the internal 8 bit recording is not good enough for you. With a swiveling LCD monitor you can easily achieve different angles without laying on the ground, and the high quality EVF is great to work with outdoors. The Micro Four Thirds mount allows you to adapt an endless variety of lenses. This camera offers the best bang for the buck and now it's $200 dollars cheaper.
Most likely it's a generic battery and sd card, but Adorama offers the same discounted price, but bundled with a spare battery + 32GB SD Card.
