The URE22 Lens adapter is used to connect the WC-E75A Wide conversion lens on to the Coolpix P7000 camera.

It is not meant as a filter adapter per se. It has a different thread pitch than standard 52mm filters. Keep in mind folks this is a single purpose item: Per Nikon, "The UR-E22 is an Adapter Ring that is required for use with the WC-E75A Wide-Angle Converter Lens to attach it to the camera".
This mounts to the camera in order to mount the Nikon wide angle lens accessory for the P7000. It is only the adapter and I called it a lens "accessory" as it allows the wide angle glass to mount up to the built in lens and is not actually a self contained piece of glass. For the "prosumer" P7000 it is quite clever and makes sense as it gives you more creative control. I hope that Nikon does a telephoto based on the same concept.
I have a new P7000 and purchased the UR-E22 Adapter Ring to be able to mount filters. 1. It is plastic. 2 It looks like it will mount standard 52mm but the thread will not mate up.
