Nikon isn't exactly quick to jump on the latest trends, as it still lacks a mirrorless camera with a truly large sensor. However, it just filled a giant hole in its lineup by launching its first action camera: meet the KeyMission 360. As the name implies, the tiny, cube-like cam is designed from the start for 360-degree images and virtual reality. It's also toughened up like many of the incumbent offerings, with drop-proofing to 6.6 feet and waterproofing to depths of 100 feet.
