The Kickstarter project Z E1 has been funded over 4x their initial goal and now proceeds to build the cameras based on a Micro 4/3 sensor and an extremely small GoPro-like camera body that does 4k video and up to 120fps HD video in an upcoming software update; the camera form factor is ideal for drone aerial photo and video. It promises professional video and photo quality with no compromises in an incredibly small body which would be close to what Olympus attempts with the Air A01 or DxO with the One. The camera does have a 2.5″ inch Screen on teh back but also relies on a 200-300ms response time over wifi which is short for little lag. The Interface is iOS and or Android and are already available for download on these platform stores for remote shooting.
