The box-shaped KeyMission 360 uses two image sensors and lenses positioned on either side to record video in 4K UHD. The footage from each lens is combined within the camera to build a single, high-def 360-degree image.
Waterproof up to 30 m (100 ft) without additional housing, the camera is built to endure dust, shocks and colder temperatures. It also features electronic Vibration Reduction, Nikon's image stabilization technology which it says will help avoid camera shake and make for clearer video quality.
What's particularly interesting about the KeyMission 360 is that Nikon is seemingly able to achieve 360-degree video with only two lenses. GoPro's own 360-degree video solution, which was announced in last year but is not yet available, counts on an array of six Hero4s to capture the action around it. Other approaches use as many as eight cameras to shoot and stitch together spherical images and videos.
There's no word yet on pricing, but Nikon says the KeyMission 360 will be released this (US) spring, along with "a variety of dedicated accessories."
