By pairing the HC-V770 full HD camcorder from Panasonic with your smartphone you can record two camera angles at once. A main image from the HC-V770's sensor in full HD and a secondary picture-in-picture image from your phone's camera. But the HC-V770 works by itself, too. It features a 20x optical zoom lens with a 29.5 to 612mm equivalent focal length - giving you a wide angle when zoomed out and a substantial amount of telephoto when zoomed in. Able to record slow-motion in Full HD at up to 120 fps, it can also perform in-camera interpolation to bring the final frame rate up to 240 fps. For steadier handheld shooting, the HC-V770 features Panasonic's hybrid O.I.S.+, which combines optical and digital image stabilization to provide 5-axis correction. Adjustable settings allow you to find a stabilization mode most appropriate for the kind of shooting you are doing. From off for tripod work, to normal for regular handheld work, all the way up to strong for those times when things really get shaky. The HC-V770's Wi-Fi does more than let you capture from your phone's camera. You can preview a live image on your mobile device using the Panasonic Image app and change camera settings. If the camera has Internet access, you can even upload web-friendly copies of videos and photos directly to social media websites. Plus, there's a baby monitor function which lets you use the camera like an IP surveillance camera, viewing a remote feed across the Internet.
