Hi, I use a 3 axis Gimbal to stabilize my camera. I need to pull focus with it for an upcoming project, but I am not sure how to do this. Is there any lightweight accessory that can help me adjust the focus on my t3i while using my gimbal? Preferably this would be wireless because my gimbal can only handle 1200g. If not, it would need to be lightweight and not interfere with the gimbal. Any help would be appreciated!
