Despite having a cropped sensor the A6500 and A6400 boat a highly reliable focusing system made up of 425 phase detection points. Not only that but they are two of the lightest and most compact cameras on the list despite having a fairly competitive sensor pixel count. If you are an aspiring or professional video shooter, the Sony A6500 and A6400 prove to be a great option for underwater video.
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.
Canon is consistently a leading manufacturer of cameras and lenses in the video realm and the 1DX MkII is their flagship camera. The color science that is characteristic of Canon systems is highly sought-after and the sharpness of their lenses is not to be understated. If you are looking for a top-of-the-line DSLR that functions not only as an amazing stills camera but also as a professional-grade video camera, the Canon 1DX MkII is for you. The downside, is that the underwater housings are somewhat larger than the other housings listed in this guide.
The A7 III, with its compact and ergonomic design, has been a very popular camera for video recording. The battery life is drastically improved compared to the previous A7 Series cameras, which was a primary complaint of Sony Alpha users and is particularly beneficial for underwater video, as it allows you to shoot for much longer without the need to open the housing. The A7 III also has dual SD card slots, which play an additional role in the maximum allotted time you can record underwater without having to open the housing. The auto-focus during video works very well.
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.
