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?

How do you take good pictures with a GoPro?


There are three things that make the RX100 series one of the best underwater camera. First, their 1-inch sensor size is larger than most other compact cameras besids the G7X II, giving better image quality and better low-light performance due to a larger pixel size. Second, the auto-focus speed is faster than traditional compact cameras. Last, but not least, is its advanced video features, including 4K video.
The Nikon Z6 is the Nikon equivalent of the Panasonic S1 -- Nikon’s lower-megapixel version of their Z Series full frame mirrorless cameras. The Nikon Z6 offers a 24MP, full frame sensor with fewer, larger pixels than the Z7 making it a more favorable choice for video due to the low light advantages. One benefit of the Nikon Z7, as compared to the Panasonic S1, is its size. The Z7 is small and compact -- a major reason why people are turning from DSLR cameras to mirrorless cameras. The Nikon Z7 has phenomenal autofocus capabilities with 273-point hybrid phase-detection contrast autofocus technology. It tops out at 4K 30p but can natively output 10-bit 4:2:2 over HDMI in the new N-log color profile, promising greater dynamic range and flexibility in post. Beyond that, with its new firmware, it will become the first hybrid camera to offer RAW video output when coupled with the Ninja V monitor/recorder.

The BMPCC4K has a built in 5” monitor, which makes viewing and framing your subjects underwater a breeze. The LCD screen on the BMPCC4K is lovely -- it’s sharp, bright and has good contrast. The BMPCC4K has no in camera stabilization, but this can be solved in post-production with the free Davinci Resolve subscription that comes included with the camera. Also, the BMPCC4K only has single-point autofocus, which is challenging when shooting video underwater. The solution to this, which most videographers prefer anyway, is to use manual focus. With the Nauticam BMPCCII Underwater Housing, there are numerous MFT lenses that Nauticam supports manual focus for. To see a list of supported lenses with the Nauticam BMPCCII Underwater Housing, see our Nauticam Port Chart.
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.
This is the Swiss army knife of tough cameras, equipped with ring lights around its lens that function as a torch as well as a macro light, allowing you to see what you're doing underwater as well as keep your subjects illuminated. While it's not a big update over the previous WG-50, it's got a fair few nifty features that make it worth consideration. The microscope mode lets it focus at distances as close as 1mm, while the Handheld Night Snap captures several images of a low-light scene in quick succession and blends them together to create a blur-free composite image. This is all housed in a body with serious protections, able to stay submerged in 14m of water for up to 2 hours. 

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.

The downside, is that the underwater housings are somewhat larger than the other housings listed in this guide.

The quick autofocus is also a key feature of the camera. 

How do I protect my GoPro?


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 next most immediate specification to consider would be the frame rate that your video camera allows you to record in. Top-of-the-line video cameras record at 4K resolution and 60 frames per second (fps), giving your footage that smooth, slow-motion cinema look that everybody loves. This is a highly sought-after capability and only a select few cameras on the market (excluding high-end cinema systems) provide this feature.
