Meet the Varavon Birdycam 2: a 3-axis motorized camera stabilization system that lets you produce professional videos of moving subjects. It balances out your camera as you follow your subjects, allowing to capture more fluid shots. The thumb-control joystick on the steering handle lets you pan and tilt the gimbal easily.
This stabilizer supports mid-size cameras, including popular DSLRs. The motors are battery powered. Birdycam 2 has a max weight capacity of 5.5 lb. More information is available here.
