One of my favourite features is the modular system that lets me swap out the lens with the 360 mod, 4k lens, or the 1-inch Leica sensor, which produces great quality video with excellent stabilisation. It's noticeably better than the 4k lens. I can even point the viewfinder screen towards me so I can see what I'm recording. The mobile and desktop apps are very easy to use in re-framing 360 videos and creating special effects. I haven't tested this, but the camera can also be used to livestream videos and as a webcam.
Physically, the camera is very well-built and sturdy despite being made up of multiple parts. I wish the standard battery also had the mount built-in like the Boosted battery, but the mounting bracket is needed for that. I also really appreciate that it's waterproof out of the box without an extra case.
I'd recommend the ONE R to anyone who wants to create or learn 360 videos as well as regular/wide-angle videos with a single system and carry less equipment. The package is great value.
