The KIWIFOTOS LA-67P520T Lens Adapter is a two piece adapter(back component & front component) made of black anodized aluminum. The lens adapter provides 67mm filter mount for adding effects filters or other lens accessories to the models of Nikon COOLPIX P510 / P520 / P530 Digital Camera, improving picture quality and protecting your camera lens. With the back component of the adapter users can add a 67mm filter to improve picture quality at the widest zoom and it will not cause vignetting. In this case lens full zoom function is not applicable. For use with teleconverter and macro/close up lenses in full zoom screw both parts together and add a 67mm filter, it may cause vignetting, however. The special design of a smooth inner ring of the lens adapter helps protect your expensive camera from scratching during installation.
