I got this filter for my Nikon D750 a few weeks ago. Being a photographer of 45+ years, and doing it professionally for about 30yrs. I was a little skeptical about these "Fader Nd Filters" because I have tried them in the past with very little success. However, I greatly admire Anthony Morganti (On YouTube) and enjoy his videos. He has one on You Tube now about this filter. I watched his video several times before I bought one for myself. I usually use a Cokin P System, but I wanted to carry just one filter with me instead of a whole system. (Older now)I can tell you this: "This is all that I hoped it to be"!!! I have tried it on many occasions in the last month, put it through several tests, and I can tell you that Anthony was right. This filter is all that the Manufacture claims it to be.(No X. Well built, 6 true stops) From the packaging to the filter case, to the filter itself, the quality is there. It is very well built, and performs wonderfully.I would not take the time to write this review, but I felt compelled to do it for others that are looking for a "GREAT VND FILTER"!!! Take a look at the video I previously mentioned, and see for yourself! I hope this is of help to someone. Maybe You! Thanks, Shooter Boone.
