Ricoh has revealed a follow-up to the WG-M1 action camera it launched two years ago, a camera that is capable of recording video at a 4K resolution at 30fps. The upgraded WG-M2 can capture footage at the high resolution, as well as 1080p video at 60fps or 720p at up to 120fps, with the device also offering seven video effect modes, on-camera editing, and a lens that provides an extremely wide field of view of 204 degrees.
