The next most immediate specification to consider would be the frame rate that your video camera allows you to record in. Top-of-the-line video cameras record at 4K resolution and 60 frames per second (fps), giving your footage that smooth, slow-motion cinema look that everybody loves. This is a highly sought-after capability and only a select few cameras on the market (excluding high-end cinema systems) provide this feature.
Which is the best GoPro for the money?
The GH5s is popular for underwater video because the camera is at a great price point, the body is relatively small, there is a multitude of micro-four thirds lenses available for any lens requirements, the video bitrate is quite high, and camera supports many video features that other micro-four thirds cameras do not support. It crushes all other micro-four thirds cameras at high ISOs with respect to noise.
The rest of the camera's highlights include Wi-Fi for smartphone connectivity (via an app), GPS, a built-in eCompass, and a temperature sensor. You can embed data from the sensors in your images when you edit them, thanks to a dedicated app by Olympus. And the 3-inch LCD display means navigating through all the camera's features is easy. The screen is considerably sharper than one found in the device's predecessor.
The SeaLife DC2000 is the best underwater camera from a company you've probably never heard of. It doesn't look that much different from the TG-5—it's about the same size, and the style and controls are similar too. But inside is a sensor that's four times the size, and a lens that's a little brighter. It's not necessarily a crowd-pleaser—the lack of zoom power and generally slow operation make it a niche camera. But serious divers will find it a good option, as it can go as deep as 200 feet using the included case, and is good to sixty feet without it.
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.
