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.

Is GoPro better than DSLR?

What is a good cheap action camera?


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.

Do you need a filter for GoPro underwater?


When we say "waterproof camera" we can mean a number of things, so it's important to define our terms. There are two main popular types of waterproof camera: waterproof compacts and action cameras. Waterproof compacts tend to resemble an ordinary compact camera, with the main difference being that they're, well, waterproof. They tend to be marked out by distinctive bright colouring (useful if you drop them underwater), and the main edge they have over action cameras is the option of an optical zoom lens, allowing you to get closer to your subjects without suffering loss of picture quality. 
The new Canon EOS Mark III 5D is a top of the line camera that was designed for photographers who want the best. With at 22MP full frame CMOS sensor it delivers high quality video with decreased noise at high ISO settings (100-25600).
