Yeah she is a big'un, zoom function from the app works flawlessly.
From memory the counter weight is 124 grams
How long have you been using this lens? have you had any issues with the gimbal on windy days, was talking to a dealer a while back and he mentioned they were seeing an increase with the X5S gimbras coming in with burnt out motors, he suspected that it was this lens frying the gimbal motors in windy conditions? any thoughts, it spooked me a bit, but i would love to use this lens.
