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.
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.
Panasonic is the latest manufacturer to release their line of mirrorless full frame cameras. They released the Panasonic S-series in March of 2019 and swept the photo world of its feet with these impressive new mirrorless cameras. The Panasonic S1 is the S-series camera designed for video, as it incorporates fewer, larger pixels that yield impressive low-light capabilities. The Panasonic S1 incorporates a 24MP, full frame sensor with a new Leica-L lens mount. The S-series cameras bested all other full-frame mirrorless lines in many categories. The Panasonic S1 (and S1R) is the first full frame mirrorless camera to shoot 4K at 60fps -- a feature that full frame mirrorless shooters have been waiting for for years. Not only that but with the latest firmware update, the Panasonic S1 can record 4:2:2 10-bit footage internally, making it an absolute workhorse for color science and post-processing workflow.
The Sony A6500 and A6400 are Sony’s top-of-the-line cropped sensor mirrorless cameras. They feature a 24MP APS-C CMOS sensor and records UHD 4K up to 30fps. The Sony A6500 offers many of the same pro-level features characteristic of Sony’s a7 series cameras, such as 5-axis image stabilization and S-Log picture profiles. The Sony A6400 offers the capability of shooting with hybrid log gamma, and an improved color science from the A6300 and A6500. Thanks to the smaller sensor, however, both cameras come at a much lower price point than the full frame a7 series.
Is GoPro good for underwater photography?
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.
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 GH5s is popular for underwater video because the camera is at a great price point, the body is relatively small, there is a multitude of micro-four thirds lenses available for any lens requirements, the video bitrate is quite high, and camera supports many video features that other micro-four thirds cameras do not support. It crushes all other micro-four thirds cameras at high ISOs with respect to noise.
Before you start digging into the reviews, a few notes on choosing a cam that's right for you. You'll definitely want to consider frame rate, expressed as frames per second (fps). Some action cameras offer up to 240fps recording, while others only go to 30fps. For standard playback, 30fps is perfectly fine. It's when you want to slow footage down in editing to create dramatic scenes that frame rate matters. Footage captured at 240fps can be slowed down and played back smoothly at one-quarter speed. You may also want to go for a cinematic look, in which case you'll want one that has a 24fps capture option, the same speed used by most Hollywood productions.
