Likely not. What matters is that the composite CG of the gimbal and camera intersect the gimbal's pivot axes. I don't know what a Nex-5 camera weighs but let's say it is 300 grams. If the camera mount hole-slop is say 0.5 mm than the resultant imbalance would equal 15 g-cm. Which means even if DJI needed to do post manufacturing balance at the factory, which is doubtful, they would have to employ a surrogate mass stand-in for the camera. It would be prone to the same kinds of hole-slop uncertainties of 15 g-cm, and beyond that, it would really be meaningless. 15 g-cm is something that DJI can likely determine via CAD and maintain throughout manufacture (considering how small gimbal is). Question, are there any correction weight positions obvious on the gimbal? DJI imprecisely touts this gimbal as the same pointing accuracy as Cloud Cap's smaller Tase gimbal. The difference is that Cloud Cap integrates the camera and gimbal at the factory. Any balancing they do is on the whole unit as opposed to the customer adding their own camera. Most gimbals that have the need for precise balancing are done on static CG machines, the majority of the remainder are done on shakers, other methods including dynamic balance are rarely used.
