The black UR-E24 Filter Adapter and HN-CP18 Lens Hood Set from Nikon
is compatible with their COOLPIX A DX-format point-and-shoot camera.
The adapter provides 46mm threads for attaching optional filters. The
hood shields the front element of the lens from glare and excess light,
and also prevents it from hitting your subject if you get too close.
Both items can be clipped together as one piece while attached to the
camera; the hood can easily be removed to allow for filter mounting and
then snapped back into place on top of the filter.
