Here at mixtus we just got in this new piece of gear called the beholder MS1. It is a small handheld gimbal similar to gimbals that you would find on a drone. We are currently testing it out with the SONY RX100iv and we are really impressed. This is a great tool for producing really smooth and professional looking video.
Here is a quick test of the Beholder while in Arizona. It is pretty easy to control.
We picked this up from a really cool company in LA called owldolly.
