Q. Is artificial (Man Made) issues such as damaging filters part of the warranty?
A. No, Any artificial issues are not part of the warranty. This warranty excludes damage resulting from abuse, accident, modifications, or other causes that are not defects in materials and manufacturing issues.
Q. Can I use filters underwater for action cameras like GoPro, Insta360, or others?
A. None of the filters should be used underwater or during water activity unless specified on the product packing.
As such, ND, ND/PL, and CPL filters have no role in improving your footage underwater; they are to be used on the ground to create motion blur in case of ND, ND/PL & removing reflection for CPL.
Using filters near heavy water activity, such as swimming, waterskiing, etc., or natural storms can build pressure damaging the optics by creating moisture.
