Drone manufacturer DJI has announced its response to news that GoPro is working on a UAV. DJI announced two new cameras for its own flagship drone, the Inspire 1. Dubbed the Zenmuse X5 and X5R, respectively, these cameras are the first aerial cameras to hit the market featuring Micro Four Thirds sensors. Each camera captures 16MP stills and up to 4K/30fps video. Additionally, the X5R is capable of capturing images and video (including lossless 4K CinemaDNG) on either an onboard microSD card or a 512GB SSD mounted just above the gimbal. What's more, each 0.75-pound camera body accommodates four interchangeable lenses (ranging from 12mm to 17mm). The pilot can even adjust the aperture and focus of the lenses from the ground while the Inspire 1 is in flight.
