Excerpt: This UR-E22 adapter, as advertised, is solely for use with the WC-E75A wide-angle lens attachment. It has an oddball 50mm thread on the front, so you can't adapt it to any filter thread, which I feel is a dumb and inconsiderate oversight on Nikon's part; 49mm or 52mm threads would have been nice.
Excerpt: Maybe because the English language or because I already used other ADAPTER RINGS in other point-and-shoot brands, I was let to assume this product would be to, besides protecting the lenses, adapt some filter I use with my D90, what is not the case. It is to adapt the Wide Converter WC-E75A.
Excerpt: 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.
