Every Lens has a different Wieght Distribution, that´s likely you dont hear any noise with the 15 mm.
Read the Thread that i posted carefully, its explained there!
Chnjab over at inspirepilots :
"However the issue of "balancing" a lens has never been described by DJI nor have the limits and technical requirements for achieving acceptable weight distribution on the X5 gimble. Upon the release of the X5 and prior to even beginning to test lenses that DJI had not endorsed I carefully measured gimble geometry, pivot points, and the weight involved and controlled by each motor and the relative static state of that weight. What I learned, primarily from the DJI 15mm but reinforced with the 12mm and 45mm was that the gimble wasn't designed to see a state of complete static balance at any motor. Upon realizing this I wanted to understand why and delved into what components have been utilized, exactly how they function, and the engineering principles at work. I arrived at a theory of the function and requirements of this design which I then began to test. Out of that theory came the parameters to apply to achieve a state of what many refer to as "balance" for the combination of a given lens and the camera components controlled by the tilt motor. More exactly the static distribution of weight of the camera and a given lens combined. This was actually only the starting point as even when one achieves the predicted optimum static weight distribution it doesn't address the tilt motors ability to raise or lower the weight that is acting upon it. This is why even though a particular lens may "balance" doesn't mean it won't overheat the motors if it is tilted forward and then raised to level again. The other issue which also isn't always realized is that the camera lens assembly isn't centered on the horizontal axis control motor. This actually reinforces the aforementioned theory of function and design though also serves to limit how much additional weight may be added."
Even if the Lens "balances" perfectly in the gimbal ( no tilting,static), it doesnt mean that it´s correct and you cant damage your Gimbal.
Maximum Weight for the given Lens is the Key.
