Here's how I balanced the Polar Pro ND Filter today. Basically I used 3x 5p coins stuck on the tilt motor'e metal housing (currently with BluTack) and (1x 2p) + (1x 20p) on the back plate (using velcro). Seems pretty balanced to me, but might not be perfect... what do you think? Interested for everyone to also confirm the gimbal dance I see on startup, do you get the same behaviour + slight drifting to the left? https://vimeo.com/95428115 (Password: phantompilots123) Slightly concerned I'm adding to much weight to the motors but it needed all that to balance as it does... 2p = 7.12g + 20p = 5g = 12.12g 5p = 3.25g x 3 = 9.75g Polar Pro ND weight = 11g Counterbalance total weight = 21.87g :?
