Insta360 has made some of the most fun and interesting cameras of the past few years and the new Insta360 X3 is no different. The X3 is a 360-degree camera with two super-wide lenses that capture everything around you, allowing you to 'reframe' the footage into a standard movie later. But a host of upgrades mean it's also now much more usable as a traditional action camera in 'single-lens' mode. But on the X3 you can now shoot in 4K resolution in this 'single-lens' mode, making it more like having two cameras in one.
