Here, we have outlined the best cameras for underwater video in order from best to last-best. Yes -- indeed the last camera mentioned has been classified as ‘last-best’ since if it were not an excellent choice for underwater video, we would not put it on this list! Here we will walk you through some of the key points that make each camera great for underwater video and hopefully make the process of choosing which underwater video camera is best for you, a little bit easier.
“As the Directors of Photography for Discovery Channel’s “Deadliest Catch” we have the responsibility to bring home high quality professional images that will be viewed by tens of millions of people worldwide. This is an awesome responsibility considering the incredibly harsh environment that we work in. All of our photographic systems are challenged by salt water, freezing spray, and violent collisions with hydraulic cranes and swinging crab pots – not to mention the times that we loose our footing and fall or get washed across the deck by waves. In this crazy environment our most reliable tool has always been the SplashCam” …more>

How much does the GoPro cost?


The Sony A7S II has been a go-to mirrorless camera for underwater video since its release in September of 2015. For the Sony loyalists looking for top-of-the-line image quality in a small and compact form, the A7S II is for you. It embodies a 12.2MP full frame CMOS sensor and can shoot true cinema 4K video at 24fps, as well as UHD 4K at 30fps and smooth slow-motion video at HD 1080p video up to 120fps. Paired with an impressive 5-axis in-camera image stabilization you can get ultra-sharp, steady footage even when shooting hand-held.

Does GoPro still make the session?


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.

Are GoPro adhesive mounts reusable?


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.

How long does GoPro 7 battery last?


The Canon 1DX Mark II has been a staple DSLR camera for professional video since its release in early 2016. It comes equipped with a 20MP, 35mm Full Frame Canon CMOS sensor and records 4K video at 60fps or Full HD video at 120fps. Very few full-frame cameras can record video at these high frame rates and a high bit-rate, which can then be slowed down for slow-motion video.

What kind of SD cards do GoPros use?


Another highly sought-after, and relatively exclusive, feature within the video camera realm is the ability to record in RAW or ProRes. These are uncompressed formats that maximize the information gathered by the sensor and provide you with extended flexibility when it comes to color grading and post-processing. As mentioned, this feature is quite an exclusive one and only available in a select few cameras on the market with good processors (again, excluding high-end cinema systems). Some select cameras can record in ProRes Raw with an Atomos Ninja V external recorder. Nauticam offers a housing for the Ninja V for use with your underwater system.
What makes the “Best Underwater Video Camera”? When shooting underwater video, or video in general, there are many factors to consider. To start, being able to record 4K video is now a luxury that is expected out of any respectable video camera and 4K capture is definitely something you should consider when choosing your underwater video camera. The good news is nearly every new DSLR, mirrorless or compact camera features 4K recording capabilities. Where it becomes complicated is the 4K Video Type, which basically is the way in which a camera records 4K video. There are three types of cameras when it comes to 4K recording. The most ideal camera is one that has a full pixel readout from a 35mm sensor (often shooting the initial video in 6K) that will downsample to 4K, adding additional details to the video. Intermediate 4K quality comes from cameras that use pixel binning to process their 4K video. The worst 4K quality comes from cameras that “crop” the video by using only part of the sensor to capture 4K footage. This produces the worst quality because less sensor area is being used to capture light while filming video. The Canon EOS R was a disappointment for videographers for this reason.

The Canon G7X III is a tiny camera with a large 1-inch, 20 MP sensor, a direct competitor to the Sony RX100 series cameras. It is an excellent, fast-focusing camera with great image quality and has dedicated macro focus. The camera also boasts 4K video, slow motion video, a bigger image buffer, a new stacked sensor, a better image processor, and quicker burst shooting over the G7X II.

Can you take pictures with a GoPro?


When we say "waterproof camera" we can mean a number of things, so it's important to define our terms. There are two main popular types of waterproof camera: waterproof compacts and action cameras. Waterproof compacts tend to resemble an ordinary compact camera, with the main difference being that they're, well, waterproof. They tend to be marked out by distinctive bright colouring (useful if you drop them underwater), and the main edge they have over action cameras is the option of an optical zoom lens, allowing you to get closer to your subjects without suffering loss of picture quality. 
Action cameras have replaced traditional point-and-shoots and camcorders for many types of underwater and outdoor work. Their small, go-anywhere designs and ultra-wide lenses make them ideal for mounting—whether it be to a surfboard or dive helmet—and they are built tough. While many of these cameras still require an external case to be waterproof, the GoPro Hero8 Black can go down to 33 feet without one, and offers class-leading video stabilization, making it our top pick.
