Long sought such an adapter for the Nikon P520. Positive was surprising that these adapters can be very clean and just screwed into the Objetivtubus the camera, although it only meant that the adapter is pushed onto the lens and quasi only clamps. However, it remains unclear why Nikon does not offer matching filter, or at least a "standard thread" in the lens donated in the standard filter can be screwed equally. Adapter worked very clean and due to the metal alloy very, very easily. To by UV filters etc the original camera lens from scratches or damage to protect, simply indispensable and cheaper than a possible repair of the camera lens.
