The big surprise was the weight of some of these filters and in particular the ND and Polarizer Filters for the Naked GoPro which are very light, which is exceptional news for anyone with a Multirotor who happens to also be running a Brushless Gimbal. Essentially this means its very unlikely its going to throw the balance of your Gimbal out or require you to reposition the Gopro to achieve correct balance on the Gimbal.
The weight difference between these two 31g as opposed to 10g, so less than 1/3 the weight.
In any case hope you find this information helpful.
