I can't answer that question, I wouldn't know how to attach such a filter either.

just ask nikon. i don't know anything about a waterproof camera. i wouldn't know how to attach the part...

I can't say, but for me it was perfect. And even more delicious. I think it used to be the other way round. It made much more sense for me to film in the sea. In the shallow water I saw her immediately on the bottom. I like it better in orange anyway. In any case, a top product. It's a Nikon. Sometimes you have to give it time to set the scjarf. Especially with water on the lens. It had a bit of a problem in the sea the night we celebrated our last shooting day with sparklers and champagne.... But it took some really sharp pictures. But any other camera would totally fail. It also survived two thunderstorms and shot good sound and pictures... simply shot against the sky. If it's cheaper: buy it... great product... you just go swimming or bathing with it or else out in the natir. I love it... and it has the same batteries as the 360 key nikon... have fun when you buy it....
