The Panasonic HC-V770 is a Full HD camcorder with 20x optical zoom and HDR (High Dynamic Range) Movie technology to deliver clear, detailed shots even with backlighting. The 4-drive lens system powers each of the four lens groups separately, reducing the drive ranges to result in high image quality, high-powered zooming, and a compact camera body. This technology works with the BSI sensor, which features 6.03M effective pixels, and the high-speed Crystal Engine, for crisp, clear pictures. You can even use your smartphone with Wi-Fi operation as a sub camera, to get footage from two different angles at the same time. Since you are shooting with different cameras, you can use one at a distance, or at any angle you choose. This gives you a wide variety of Picture in Picture images.
