Much of GoPro's success can be attributed to its diverse ecosystem of accessories. DJI clearly had this in mind when making the Action 2. Measuring roughly 1.5" x 1.5" and weighing in at just 56 g, the highly portable camera has a magnetic attachment system to support lanyards, headbands, and more. It has a 12-megapixel CMOS sensor that captures 4K video at up to 120fps, with an ultra-wide 155º field of view and a built-in stabilization algorithm. Drop-proof, dustproof, and waterproof at depths of up to 10 meters (or up to 60 with an optional waterproof case), it also lives up to its "Action" name.
