Hi all, i'm wondering what the safest mattebox to put on a black arm / russian arm is for a car commercial where i assume the DOP will use polarizers and different filters while shooting. (And i want a clear filter in front of the lens for possible chips flying from the car we're filming.) Obviously i feel like a clamp on mattebox feels a bit risky. But wouldn't a mattebox with rods cause small vibrations near the lens while going at faster speeds?
What's your experience with this? What works, and what doesn't?
