Feiyutech a200 Professional Gimbal
Want to know the secret to getting ultra smooth video? This is one of my favorite gadgets. Granted, my forearms tend to ache after using it for several hours, but the final product is worth the pain. Note: admittedly learning how to properly balance your camera does take time to master. Have that expectation in advance.
I have plenty of these around the house for multiple purposes. First, they're just plain cool. Second, when you want to throw a color on a wall, they can turn around 6 million colors (I haven't personally counted them, but it's on my "to-do" list).
