Okay, I see uv and other filters offered for these cameras. Many, of course, are for use on the outside of the waterproof housing. However, my interest is using the camera without waterproof housing. I see filters sized 37mm and 52mm, among others.
Question:
Will a 37mm filter work without issue or will this size cast hardware, shadow,/ or other anomaly on videos and pictures? Why might one use a 52mm filter?
Will a uv filter effect the camera's automatic exposure?
Any other issues I should be aware of?
