Xiaomi has launched the updated version of the YI Action Camera, the YI 4K Action Camera, which, as you can tell, now records in 4K.
The YI 4K has a 12 megapixel Sony IMX377 sensor, that can also shoot stills in native resolution along with 4K video. The lens is a seven element piece with 155 degree viewing angle and f2.8 aperture. The six axis gyroscope enables the electronic image stabilization. On the back is a 2.19-inch touchscreen LCD.
Along with 4K at 30fps, the camera can also record in 2.5K at 30fps or 1440p at 60fps. If you want slowmotion, you can either record at 1080p at 120fps, 960p at 120fps, or 720p at 240fps. You can also shoot time-lapse videos in 4K at 0.5/1/2/5/10/30/60 second intervals. The camera includes dual-band 2.4GHz and 5.0GHz Wi-Fi and Bluetooth 4.0 to pair with your phone. The internal 1400mAh battery can last for around 2 hours while recording 4K video.
The YI 4K Action Camera will be available in black, white, and rose gold, and is priced at 1199 yuan.
