Ultimately, your choice in action camera should come down to performance and ease of use. We've filmed hours of footage with many of the major contenders to determine where each device stands in the field. Some excel in all manner of extreme situations, while others can fall apart underwater or once the sun goes down. And what good is an action cam if it's not built for action?

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.
The Olympus OM-D E-M5 Mark II is a powerful 4/3 mirrorless camera. It has 16-megapixels but is also capable of shooting in a 40-megapixel (64 in RAW), high-resolution shooting mode. The E-M5 Mark II also has WiFi to make sharing photos with your dive buddies even easier. This camera is a great option for photographers who travel often and want a camera that won’t break the bank. 

The Sony RX100 VI is our choice for best underwater camera for macro. This camera boasts a 24-200mm lens that can produce incredible magnifcation for even the tiniest subjects. The zoom and optical quality of this new lens has the capability of producing stunning, detailed macro, and super-macro images – especially when paired with a wet lens. The quick autofocus is also a key feature of the camera.

You can get great wide-angle photos with the RX100 VA/VI and the UWL-09 super-wide lens,the Kraken KRL-01, or the Nauticam WWL wet wide-angle lens.  For macro with the RX100 VA/VI cameras, we recommend using the Bluewater +7 if you are just getting the hang of macro and super macro photography. The Nauticam Compact Macro Converters (CMC-1 & CMC-2) are top of the line wet lenses with amazing lens sharpness but have a lot of magnification and can be a little more difficult to use.

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. 


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.
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.

We believe that all moments spent exploring marine life are worth capturing. This belief, along with our passion and dedication to marine life, has led us to create our high quality SplashCam underwater cameras and underwater video products. Since 1988, our goal has been to give you the opportunity to document your underwater experiences and gather invaluable HD underwater footage.
The FT30 isn't the newest waterproof digital camera here, and doesn't quite offer any best-in-class specs, but what it does offer is commensurate with its very reasonable asking price. It’s also pleasingly slim enough to fit in a snug jeans pocket or similar, although this does come at the cost of a secure grip; you might want to invest in a wrist strap to ensure the FT30 doesn’t get away from you. Provided you keep hold of it, the FT30 is a solid and versatile waterproof camera that should prove well-suited to recording your aquatic adventures – in stills form, anyway. The lower video resolution of 720p means that if you’re a video aficionado, you’re probably better off with one of the other waterproof digital cameras on this list. 
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.

“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.

The Sony RX100 VA, VI & VII cameras are the latest additions to the Sony RX100 series and are packed with lots of awesome features for underwater photography. They are the top of line compact cameras to date. Autofocus is lightning quick in both cameras, which is very beneficial for underwater application. Both feature a large 1" sensor with 20 MP resolution, which provides excellent image quality, fast autofocus, useful video modes (like slow motion) and full manual controls. The RX100 VI's key upgrade is its enhanced zoom using a 24-200 mm f/2.8 – 4.5 lens. The RX100 VA's key upgrade is 24fps sequential shooting, enhanced image buffer, and a customizable menu system. The RX100 VII has some minor improvments over the VI.
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.

These add-ons cost you more – but if you are looking for the very best action camera, and the best GoPro for image quality and features, then the Hero8 Black is it. 

Are GoPro accessories interchangeable?


The highlight of the RX100 VI over the RX100 VA is its unprecedented macro capability. The zoom on the 24-200 mm f/2.8-4.5 zoom lens cannot be beaten by other compact underwater setups. Details captured with this lens are remarkable. When combined with a wet macro lens (diopter), the realm of super macro photography is attainable. The tiniest details of the smallest subjects can be captured with this set up (once you get a little practice in of course). 

Which GoPro accessories to get?


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.

The RX100 VA introduced an increased image buffer, burst shooting up to 24fps, and customizable menus. This is excellent for photographers seeking to capture quick pelagic animals that need good burst speed and more processing power. The RX100 VA still carries all of the advantages of the RX100 V including the 315 point phase detection autofocus system and the 20 MP/1" Exmor RS BSI CMOS sensor. The main advantage of the RX100 VA over the VI is that the RX100 VA is able to shoot with both macro and wide-angle wet lenses on the same dive. This is because the lens is shorter and has less zoom capability than the RX100 VI. You also don't need to purchase additional ports/adapters for dedicated wide angle and macro set ups.
So what makes a good underwater camera? In addition to image and video quality, there are several other important factors to consider, like the overall quality of the camera's optics, including zoom range and maximum aperture. The latter is crucial for low-light photography, as larger aperture typically results in better photos since it allows more light in. It also minimizes motion blur, making larger apertures perfect for action shots. (Note: The smaller the number, the larger the aperture.)

Now, as mentioned previously, the 4K Video Type is an important factor to consider as well. In order to record 4K 60p, the Panasonic S1 crops the sensor to a APS-C sensor at 4:2:0 8-bit. Although this is not as impressive as the Full Frame 4K 60p recording available with the Canon 1DX MkII, it is still a leap forward in full frame mirrorless technology and a particularly favorable feature.
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.
