Have decided after long analysis on the Internet for this original NC-filter and no regrets. NC = Neutral Clear. The NC filter I use on a Nikon 1J1, 10-30 mm lens. He fits perfectly as expected, is indeed genuine accessories Nikon ;-). On this objective, I let him screwed up today. The quality of the images has not become worse through the filter insert, even better. Through the glass of the NC filter even reflections have been reduced in the lens in bright sunlight. Need from time to wipe dust to the screwed-NC-filter with the lens cloth. That's all :-). I am very satisfied and would recommend this NC filter.
