The DJI Osmo camera is an almost unique product. It produces super smooth fully stabilised video in HD or 4K and it is a joy to use all at a very reasonable price. It can be used instead of a gimbal or stabiliser, or with a car and bike mount, on a tripod, or handheld. It has 1 hour of video shooting per battery charge.
See the Z Axis stabilisation add on that significantly reduces vertical shaking from natural arm movements when walking or jogging. www.mediadoghire.com/DJI-Z-Axis-Osmo
