4 Yi 4K Action Camera
You don’t get much in the box with the Yi 4K Action Camera, but there isn’t much else that can rain on your parade with this affordable device. Yi’s action cam does indeed shoot in 4K, and thanks to an excellent lens and Sony Exmor-R sensor the quality is top-notch. The only downside is that its 155-degree angle of view isn’t as wide as the other models on test. Although there is image stabilisation in resolutions lower than 4K which – combined with the 720p 240fps mode – creates impressive slow-mo footage of your activities.
