The 10 best GoPro and action cameras in 2017
They're small, they're simple, and they're tough.
Action cameras are unlike any other kind of camera. They're designed to be attached to helmets, surfboards, cars and other objects, and they're small, tough and simple to operate, with a lens that captures the world in high-definition video and in a wide-angle fish-eye perspective.
Their small size and dramatic POV ('point of view') footage has made them popular with extreme sports participants, who capture their adventures by attaching cameras to themselves or their equipment. They're also used by TV production companies where using a regular video camera would be impossible.
GoPro is the market leader with its iconic box-shaped Hero cameras, but action cams also come in a 'bullet' style, like the iON Air Pro. There's lots of choice now, and you shouldn't just buy on brand – think about what you want from an action camera and how you plan to use it.
If you're helmet-mounting, then a bullet cam will probably be the best choice. For a chest mount a box design will be more stable. And when it comes to features, do you really need Wi-Fi, 4K, GPS or even a screen? These all bump up the price, and while they are invaluable in some situations, you can still get great footage without them.
