Then there's resolution and video quality. You'll want a camera that can record in 4K for sure. The top-end models from DJI and GoPro offer 60fps 4K with digital stabilization that's absolutely incredible. They're also not limited to ultra-wide views; you can set a narrower angle to remove lens distortion, making them solid choices for vlogging and travel logs.
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.
Does GoPro 7 zoom?
While the original Sony RX0 drew plenty of attention for its 1-inch sensor in a tiny body, it was somewhat hamstrung by the fact that to record 4K video it needed to be physically tethered to an external recorder. So while it was waterproof, shockproof and all that jazz, this limitation meant you couldn't record 4K video in these extreme situations. The RX0 II does away with this restriction, recording pristine 4K video internally, and also adds welcome extra features like a flip-out screen. It's the most expensive on this list, but if you need the low-light latitude a 1-inch sensor gives you, it's really an unrivalled prospect.
What comes with the GoPro 7?
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.
