THE BEST ACTION CAMERA YOU CAN BUY
Action cameras — those blocky little cameras you use when you want to record all kinds of intense moments, such as skydiving, white water rafting, high-speed go karting, and more — have been around for a while now. In the past few years, action cameras have developed from niche curiosities into really popular devices that can capture amazing footage. But every year it’s still the same story: market-leader GoPro releases a new camera, and other companies desperately try to catch up. Some companies have come close to making one as good as its best, but as soon as they do, GoPro releases a new one.
This time around, however, GoPro’s releases were aimed at the low end. That means all of its competitors had a year to catch up to the company’s two standard bearers: the Hero 4 Black and the Hero 4 Silver.
The most important thing an action camera should do is shoot beautiful, high-quality footage, with different options for resolutions and framerates. It should also have a great system of accessories and mounts so you can put the camera anywhere and use it to record anything you’re doing, which means it also has to be small and light enough that it’s not a burden to wear. Action cameras should also be easy to use, with good on-camera controls and a great companion app for your smartphone.
