>>2701976You mean you just want stabilized motion? You use a gimbal for that. It basically uses a counter weight to cancel all the motion of the camera so you can carry it around without shakiness.
The industry standard is steadicam, but those are very expensive, so a lot of people use glidecam. The lighter your camera is, the cheaper the model you can get. Whatever model or brand you choose, they take a lot of practice to get reasonably stable footage, and it's going to be significantly heavier than the camera by itself.
