For any cameras from 4 to 10 pounds, the Glidecam HD4000 is a great walking and running stabilizer we have here at the studio. The quick release plate makes it nice and easy to put on and take off the camera. It's free floating, 360 degree pan and tilt really gives you the variety of angles needed for any running or walking shot. Simply counterbalance the weight of your camera with the adjustable weights on the system itself, and you're off to the races. Great for those unsturdy, quick shots.
