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?
If the DC2000 is SeaLife's serious camera, the Micro 2.0 WiFi is its fun one. With a fish-eye lens, a 200-foot depth rating, and big buttons that are easy to press, even when wearing gloves, it's a point-and-shoot for deep sea exploration. Add-on lights are available, also rated for extreme depths, to shed some light on subjects obscured by murky waters.
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 feature-set and price point of the DJI Osmo Action make it pretty obvious from the get-go that it's an attempt to undercut the GoPro HERO7. Does it succeed? Like all things, it's complicated. The front-facing screen is a boon, the stabilisation is just as silky smooth as the HERO's, and it's wallet-friendly price is nothing to sniff at. That's not to say it's perfect; there are a few lag issues at high resolutions, the app can be unreliable, and video from the HERO is a touch flatter, which counts in professional realm when it comes to the grade. For an affordable alternative to the HERO7 Black though, the Osmo Action is a fantastic choice.

Which underwater camera is best?


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.

Is a GoPro good for everyday use?


Action cameras like GoPros have their advantages too though. They're generally much smaller than waterproof compacts, making them lighter and easier to mount via a chest harness or helmet mount or similar. The best action cameras also tend to have better video specs, offering pristine 4K in high frame rates, which many waterproof compacts currently lack.
The TG-6 can capture excellent 12 MP stills in up to a whopping 20 frames per second, as well as ultra crisp 4K video via a 4-times magnification optical zoom lens with f/2.0 aperture. Microscope mode for ultra close-up shooting is also among the camera's features, as is the ability to capture panoramas and time-lapses. Advanced photographers have the option to save their images in RAW file format for more extensive edits.

The design of the Fujifilm FinePix XP140 is fun and kid-friendly, making it a solid choice for family holidays, but this doesn't mean it skimps on imaging tech. While it's not going to challenge something like the Olympus Tough TG-6, it's a capable little camera in its own right, able to shoot 4K video (albeit at a disappointing 15p) and equipped with an impressive 5x optical zoom lens with an equivalent focal range of 28-140mm, and all this comes at an extremely friendly sub-£200 price tag. A new scene recognition mode helps the XP140 assess for what it's photographing (which goes some of the way towards compensating for a lack of manual controls), and the controls are well laid-out and easy to use, even when in murky underwater conditions. For the price, this is a really solid buy.


The latest flagship GoPro model is our favorite action camera available right now. A key difference from its predecessor (and especially the less expensive Hero7 Black) is that there are fold-out feet, giving you the advantage that the camera mount is now built in. Furthermore, you can accessorise the Hero8 Black with a new series of bespoke optional extras called Mods – we particularly like the Display Mod, which adds a second monitor that is perfect for vloggers, but there are plenty of others, including a Media Mod for improving the production value of your videos, and a Light Mod LED light too. 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.
