Nikon has announced its new KeyMission line of shooters, marking its entry into the 360-degree and action camera business. The KeyMission 360 can corral 360-degree video in 4K UHD at 24p, as well as in the more traditional HD 1080p. It also shoots 30-megapixel stills. The unit has two f/2.0 lenses, each with a 20-megapixel CMOS sensor. The dual units eliminate a bane of 360-degree cameras: blind spots. Other features include automatic in-camera stitching; shooting modes like Superlapse, Time-Lapse and Loop; and a built-in stereo microphone.
