In looking through my accessory cabinet, I
came across a large number of filters and adapters in all the standard
Nikon sizes. I even have a collection of 46mm filters from when I owned a
Leica. Those will fit on Nikon's UR-E5 without additional adapters.

The area where the lens comes out from the
body is threaded for Nikon's proprietary accessories. There is a lens hood
(HN-E5000), Step Down Ring Adapter (UR-E6) which allows you to use the
accessory lenses from the CoolPix 990/995, and the Step Down Ring Adapter
(UR-E5) which adapts the CoolPix 5000 to 46mm filter threads. The
UR-E5 is also needed for the new 19mm (equivalent) WC-E68 wide angle lens.

Behind the filter you can see the lens which zooms within the adapter.
