This nikon nc 405 neutral colour filter is designed to protect your lens from dust and scratches when in use it fits neatly over the front lens element and will not affect the colour balance of your photographs thanks to its special multi coating and if it does get scratched then its a lot cheaper to buy a new filter than a new camera lens fits all lenses with a 405mm thread such as those of the nikon coolpix p7700 camera and the nikon 1 nikkor 11 275mm f35 56 lens
