For making run and gun video's.
Besides the video quality being amazing with this tiny camera, it is also quite capable of some amazing features.
I use this setup for making most of my video's. The cage is from Ulanzi, along with the extendable selfie stick. I use the RODE Wireless Go microphone almost all the time for the best audio. I also have the RODE Micro shotgun mic that I sometimes use. The GoPro 3.5mm mic adapter fits nicely into the bottom of the Ulanzi cage.
The GoPro is the way to go if you're looking for a small compact video rig that's extremely easy to use.
