The Xiaomi Yi Camera offered most of what the low end GoPro Hero cameras brought to the table but for much less money. Now Xiaomi is releasing the Xiaomi Yi II which is a 4k capable action camera sporting the Ambarella A9 chip with a Sony IMX377 sensor and an f2.8 lens.
For the price of $249.99 which is extremely low for a camera of this caliber; you get a 30p 4k capable imaging body with the added benefit of 240fps at 720p resolution, 120fps at 1080p and 960p and the 2k 60fps spec to boot. For giggles there is also a pink version of the camera that might appeal to the female users.
