Three axis gimbals like the Hohem iSteady Pro 4 are an easy and cheap way to dramatically up your action camera video quality. For the past few weeks, I’ve been using it with the DJI Osmo Action to test its performance with walking, running, and more artistic motions. In addition to helping with unsteady action, they can give you a more cinematic look, or let you program keyframes for very specific movements.
