The OH50 allows the camera/bar to be horizontally positioned for overhead/top down photo and video shots. Perfect for product photography and "how to" videos. The mounting sled can be mounted to tripods with 1/4 20 and 3/8 screws. The mounting sled also has 2 1/4 20 holes for mounting lights and monitors. Smartphone holder and ball head allows for full range of camera/ smartphone angles. Adjustable length and counter weight holder allows for extra stable smooth shots! Recommended for tripods/ stands with payloads of 10lbs or more. For best results, mount the OH50 on a tripod that is securely seated on a table top that you are filming. Use the ball head to adjust the orientation of your shot. For cameras without a articulating screen we recommend using a monitor to frame your shot.
