GoPro's all-new HERO8 Black is the best waterproof camera for capturing video. It's capable of recording great-quality, 4K content at up to a brisk 60 frames per second. Most importantly, in line with GoPro's action-sports credentials, the HERO8 videos feature superb image-stabilization tech. Rather impressively, the latter is even better than the one used in the device's already fantastic predecessor.
The Sony RX 100 III is one of the most popular options for underwater photographers looking for the balance between image quality, price, size and ease of use. It’s a step up from the RX 100 II. This model has a better video bit-rate and adds an electric viewfinder. The RX 100 focuses faster that most other compact cameras. It’s a great option for pro photos without the weight and bulk of a dSLR camera.
While the GH5 was the first mirrorless camera to record 4K 60p, the GH5s takes it one step further and can record 4k 60p in Cinema 4K (4096 x 2160) -- a version of 4K recording that maximized resolution. The GH5s is also capable of internal 4:2:2 10-bit recording, which delivers even stronger than the color reproduction. It can also shoot HD at 240fps, and you can use a Vlog-L color profile for great dynamic range.
Then there's resolution and video quality. You'll want a camera that can record in 4K for sure. The top-end models from DJI and GoPro offer 60fps 4K with digital stabilization that's absolutely incredible. They're also not limited to ultra-wide views; you can set a narrower angle to remove lens distortion, making them solid choices for vlogging and travel logs.
