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 feature-set and price point of the DJI Osmo Action make it pretty obvious from the get-go that it's an attempt to undercut the GoPro HERO7. Does it succeed? Like all things, it's complicated. The front-facing screen is a boon, the stabilisation is just as silky smooth as the HERO's, and it's wallet-friendly price is nothing to sniff at. That's not to say it's perfect; there are a few lag issues at high resolutions, the app can be unreliable, and video from the HERO is a touch flatter, which counts in professional realm when it comes to the grade. For an affordable alternative to the HERO7 Black though, the Osmo Action is a fantastic choice.
Which underwater camera is best?
Now, as mentioned previously, the 4K Video Type is an important factor to consider as well. In order to record 4K 60p, the Panasonic S1 crops the sensor to a APS-C sensor at 4:2:0 8-bit. Although this is not as impressive as the Full Frame 4K 60p recording available with the Canon 1DX MkII, it is still a leap forward in full frame mirrorless technology and a particularly favorable feature.
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.
There are some cameras that were made specifically for being used underwater for example the SeaLife DC1400. But, just from reading the mixed bag of customer reviews on Amazon, it’s clear that it’s not the best underwater camera for scuba diving. The buttons stick, the flash doesn’t work, the shutter delay is insanely slow… just a few of the problems you can run into.
Can we take photos in action camera?
Most models have a single lens, with an ultra-wide angle of view, so you can experiment with mounting and get a big view of the world in frame. Some dual-lens cameras, like the recently announced GoPro Max, capture a 360-degree view of the world. VR playback isn't as popular as it was at the peak of the fad, but editing tools make it possible to convert 360-degree footage into a 16:9 playback format in creative ways.
Does GoPro 7 record sound?
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.
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.
