I have used Coolpix cameras years ago but my preference in point and shoot is Canon.
With my now gone Powershot camera, when I was in need of a filter, I used one of my filters for SLR lenses in front of the point and shoot lens. It is not convenient but it worked for me.
I am sure stores like Adorama and B&H in NY can give you the info you need. Nikon also could help you with this one.
