A buddy and I were talking polarizers and neither of us know whether there are generic polarizing filters that you can attach to a point & shoot? Not even sure that would work with the zooms.
Consult the instruction manual or look at the end of the camera’s lens barrel. If it is threaded the manufacturer (and an after market co.) probably makes filters for it.
I have a Canon P&S with a zoom lens and it will accept some filters.
