The A7 III, with its compact and ergonomic design, has been a very popular camera for video recording. The battery life is drastically improved compared to the previous A7 Series cameras, which was a primary complaint of Sony Alpha users and is particularly beneficial for underwater video, as it allows you to shoot for much longer without the need to open the housing. The A7 III also has dual SD card slots, which play an additional role in the maximum allotted time you can record underwater without having to open the housing. The auto-focus during video works very well.
Another particularly exciting camera that we are anxiously awaiting, and which should be released anytime time now, is the Sony a7S III. Due to the success of the Sony a7s II we think the a7S III will be an even more exciting release. When Panasonic announced 6K capability in the S1H, there has been some speculation that Sony may try to match this capability with the a7S III, but it’s impossible to know.
What makes the “Best Underwater Video Camera”? When shooting underwater video, or video in general, there are many factors to consider. To start, being able to record 4K video is now a luxury that is expected out of any respectable video camera and 4K capture is definitely something you should consider when choosing your underwater video camera. The good news is nearly every new DSLR, mirrorless or compact camera features 4K recording capabilities. Where it becomes complicated is the 4K Video Type, which basically is the way in which a camera records 4K video. There are three types of cameras when it comes to 4K recording. The most ideal camera is one that has a full pixel readout from a 35mm sensor (often shooting the initial video in 6K) that will downsample to 4K, adding additional details to the video. Intermediate 4K quality comes from cameras that use pixel binning to process their 4K video. The worst 4K quality comes from cameras that “crop” the video by using only part of the sensor to capture 4K footage. This produces the worst quality because less sensor area is being used to capture light while filming video. The Canon EOS R was a disappointment for videographers for this reason.
The highlight of the RX100 VI over the RX100 VA is its unprecedented macro capability. The zoom on the 24-200 mm f/2.8-4.5 zoom lens cannot be beaten by other compact underwater setups. Details captured with this lens are remarkable. When combined with a wet macro lens (diopter), the realm of super macro photography is attainable. The tiniest details of the smallest subjects can be captured with this set up (once you get a little practice in of course).
Which GoPro accessories to get?
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.
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.
