Has anyone had any luck with rain defectors on their Movi? The spin tech is about about 615 grams. http://www.innovision-optics.com/prod/spintec.shtml
I have one , It's very noisy. due to the spin , it will exert a force on the camera. The image quality drops, promist filter like. Unless you are in a situation where the water is spraying directly into camera. I wouldn't recommend it. Better to create a hood around the lens.
