Yi Technology 4K+ Action Camera

The world’s best-value action camera

- JamIe Carter

The Yi 4K+ isn’t hugely different to the original Yi 4K, apart from the ability to shoot 4K video at 60fps. Filming at that resolution means a maximum bitrate of 120Mbps, which is double what the previous Yi 4K offered. Bear in mind that although the Yi 4K+ does have electronic image stabilisation onboard, that only works when shooting 4K at 30fps.

Inside is the same 12MP Sony IMX377 1/2.3in Exmor R CMOS sensor, but this version has a new Ambarella H2 and quadcore ARM Cortex A53 processor. They work terrifically well together, allowing the operating system to work fluently and without a hitch despite the higher bitrate. 

You’re probably not going to use the Yi 4K+ much for photography, though that’s possible. It shoots very usable 12MP images, and it’s possible to save in JPEG or keep the raw files, which it outputs in DNG format. It doesn’t deal in HDR, but since it shoots in raw that’s no big deal.

Unlike the originalYi 4K, this new version recharges via a USB-C port, and there’s an adaptor for an external microphone in the box. It takes a microSD card up to 64GB.
