This is a really smooth gimbal. I only have one complaint and I can't install my 5dmiii with an extra battery grip. When installed, it rubs against the swivel arm and thus prevents flush mounting. Another thing to note is that if you're tracking moving objects like airplanes, birds in flight, or anything else that requires you to change the vertical field of view by more than 20º, you'll be redirected to the attachment. This can be solved by adding some padding to the mount, but this changes…
