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?
Like I mentioned, underwater housings can cost more than the camera itself so choosing the right one is an extremely important decision. They do more than just keeping your camera dry. They also protect it from pressure, allow you to use the camera controls, enable the use of different lens ports and hold accessories like lighting. Be sure to invest wisely on this one!
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.
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.
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.
