There are three things that make the RX100 series one of the best underwater camera. First, their 1-inch sensor size is larger than most other compact cameras besids the G7X II, giving better image quality and better low-light performance due to a larger pixel size. Second, the auto-focus speed is faster than traditional compact cameras. Last, but not least, is its advanced video features, including 4K video.

The GoPro Hero 6 is the most advanced GoPro action cam on the market today. It’s a great option for shooting video. It features SuperView™, a exclusive video mode that captures the world’s most immersive wide-angle perspective. It allows you to capture more of your surroundings in the shot compared to the earlier Hero models. It’s not uncommon to see a pro $20,000 underwater rig with one of these tiny cameras mounted on it to record high quality video while the photographer shoots stills.

We've added a couple of models to this ranking since we last visited it, including the Marcum LX-9, which boasts some serious resolution, as well the ability to toggle between black and white and color modes, which can make finding certain fish in certain waters much easier. Its price is the only thing that kept it from breaking into the top slot. Our top pick moved up from the number four position mainly on the strength of its battery, which far outlasts most of the competition.
The Olympus OM-D E-M5 Mark II is a powerful 4/3 mirrorless camera. It has 16-megapixels but is also capable of shooting in a 40-megapixel (64 in RAW), high-resolution shooting mode. The E-M5 Mark II also has WiFi to make sharing photos with your dive buddies even easier. This camera is a great option for photographers who travel often and want a camera that won’t break the bank. 

How do you take good pictures with a GoPro?


GoPro's all-new HERO8 Black is the best waterproof camera for capturing video. It's capable of recording great-quality, 4K content at up to a brisk 60 frames per second. Most importantly, in line with GoPro's action-sports credentials, the HERO8 videos feature superb image-stabilization tech. Rather impressively, the latter is even better than the one used in the device's already fantastic predecessor.

There have been many improvements in the compact camera lines over the past few years. Larger sensors, faster focusing, and more controls have all led to a selection of cameras that work smoothly, keep size tiny and are functional with a variety of lenses and accessories to round out your underwater photography experience. Sony and Canon have both given their compact cameras one inch sensors, and greatly improved focus speeds over the cameras of a few years ago. Olympus continued to add features to their cameras while keeping both price and size down.

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. 

How do I set up my GoPro hero 7?


So what makes a good underwater camera? In addition to image and video quality, there are several other important factors to consider, like the overall quality of the camera's optics, including zoom range and maximum aperture. The latter is crucial for low-light photography, as larger aperture typically results in better photos since it allows more light in. It also minimizes motion blur, making larger apertures perfect for action shots. (Note: The smaller the number, the larger the aperture.)

What are the best GoPro accessories?


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.
