Featuring a second camera attached to the edge of its articulated screen, the Panasonic HC-W570 HD Camcorder can capture two simultaneous streams of video and record them picture-in-picture. This way the main camera can be focused on your subject while the secondary camera records a self portrait. At the front of the camera is a 50x optical zoom lens whose zoom can be digitally extended to 90x. When shooting at the further end of the zoom range, the 5-axis stabilization can compensate for handheld vibration and reduce blur in your videos. Twin Camera Operation A rotatable sub-camera lets you take shots from two angles at once. You can capture the family and take a selfie in both telephoto and wide-angle shots. A backup function records a picture-in-picture image and a main camera image. The sub camera image is recorded into any one of various sub windows, and its display position can be changed with a simple touch of a button. Alternatively, using your smartphone's Wi-Fi, you can use your smartphone's camera instead of the sub-camera to shoot from any distance or angle you choose for a variety of Picture-in-Picture images. Level Shot Function Level Shot automatically detects and corrects tilting in images. It can be adjusted to three different levels-OFF, Normal or Strong-depending on shooting conditions. 5-Axis HYBRID O.I.S.+ From wide-angle to powerful zoom shots, HYBRID O.I.S. + uses five-axis correction to suppress blurring.
