There was a time when GoPro was the only option for most people choosing an action camera. Times have changed, and now there are multiple options to capture your sports escapades. The DJI Action 2 camera ticks all the right boxes: compact, waterproof, drop-poof and expandable thanks to its magnetic mount system. The camera module itself is quite small, but still captures 4K footage at 120 frames per second, and has a wide angle lens. But the magnetic system means you can clip on extras, such as a power pack, a front touch screen module aimed at vloggers, and a range of easily swapped mounts.
