The Sony A7 series has led the charge in full frame mirrorless cameras and the A7 III and A7R III have been some of the most popular cameras on the market since their release in April 2018. Similar to the Nikon Z6 and the Panasonic S1, the Sony A7 III has fewer, larger pixels compared to the A7R III and therefore, a more favorable for video use due to the resulting low light capabilities. The A7 III tops out at 4K 30p and records internal 4:2:2 8-bit video. You also have the ability to shoot on various picture profiles like HLG & S-Log3 Gammas, which offer less-compressed video capture and facilitate maximum color rendition and dynamic range for post-production flexibility. It also has impressive autofocus capabilities with a 693-point hybrid autofocus system.
The W300 does have GPS, Bluetooth, and Wi-Fi connectivity for seamless smartphone connectivity. The rest of its highlights include a 3-inch LCD display and a quartet of environmental sensors whose data you can add to your images. They include a barometer, a compass, a built-in depth gauge, and a thermometer. Nikon offers the camera in black, yellow, and orange.
The Blackmagic Pocket Cinema Camera 4K (BMPCC4K) is known as a disruptor camera, as it offers most of the features videographers hold in high regard at an impressively affordable price. The BMPCC4K has a Micro Four Thirds sensor, records 4K video at 60fps and even records RAW and ProRes files. This small, highly affordable cinema camera offers key features that were previously held captive by top-of-the-line, high-budget demanding cinema systems like the Canon C200, RED Digital Cinema Cameras, or the Arri Alexa Series. Recording in RAW or ProRes provides you maximum flexibility during post-processing and allows you to apply professional color correction to your footage.
You may already own a waterproof camera. The latest top-end iPhones and Android phones are IP rated for submersion for short amounts of time. And the rise of quality smartphones has gone a long way in reducing the number of dedicated point-and-shoots on the market. But even if you're just taking a quick dip and want to snap a selfie, there are reasons not to take your expensive phone into the water.
The latest flagship GoPro model is our favorite action camera available right now, and it brings some brilliant new features. A key difference from its predecessor (and especially the less expensive Hero7 Black) is that there are fold-out feet, so now you have a camera mount is now built in. That's not all – you can accessorise the Hero8 Black with a new series extras called 'Mods'. We especially like the Display Mod because it adds a second monitor that is perfect for vloggers. There are plenty of other Mods too, including a Media Mod for improving the production value of your videos, and a Light Mod LED light too. These extra capabilities – and the fact it's already waterproof down to 10m without a case – make the Hero8 Black our favorite underwater action cam right now.

Fortunately, we are now blessed with several cameras and great underwater housings that meet these criteria for the "best underwater camera". Whether you are looking for the best underwater camera for scuba diving or snorkeling, we are sure you will find it here. I'd also like to point out, that we define a compact camera as a camera with a fixed lens.
