Tube Adapter Nikon

Tube Adapter Nikon
How exactly do you put a Fisheye Lens on a Nikon Coolpix 5700?

You just screw it on there?? Or do you need like an adapter tube or something like that???

This is from Nikon. What does the manual say?

When connecting any of the converters to the camera a lens adapter is required: The UR-E12 for the FC-E9.
