Other reviewers have explained the drawbacks with the nd filter "X" happening if you go all the way ND. But I never go that far and it works wonderfully for being so cheap. And it took fall from tripod height my lens hit the side of a piece of wooden furniture and the filter popped off and was just fine. A little scratched but I still use it.

this thing arrived to me in an envelope.. i tested it right away and i was disappointed to find out when the dots and arrows on the ring didnt match when you spun it to change the grade... Also I have to forcibly rotate it just to get from min to max. my other ND filters from fotasy rotated smoothly, unlike this one where it would stop mid way.. I thought fotasy was cheap but this one is beyond cheap. the funny thing is fotasy was way cheaper and better.

I would consider my self a advanced amateur and have used several products of this nature in the past. it worked great for one week, but near the end of our Hawaii trip, I dropped in the grass, and now it is out of alignment and unusable. Just a soft landing should not have such a detrimental effect. I would not recommend due to quality concerns.

Optical quality of this filter is decent--I did some side-by-side comparisons with and without and it seems to not degrade image much. I wish there was a multicoated version, as this one appears to be uncoated, which results in more flare and less contrast. You would expect to pay more for coatings, however. The very highest density is unusable due to the uneven purple color. I can make about a 6 stop change before I notice any image degradation. By 7 to 8 stops, you start to notice uneven bluish vignetting, and by the 9th stop, it's just ridiculous. So maybe this is effectively a ND2-128 variable filter, or something in that range. It still serves me well, as I mostly want this for doing daytime video wide open on a fast (1.4) lens, using 1/60 (180 degree) shutter speeds. These drawbacks are typical of a variable polarizer, and any filter at this price, so these do not affect my rating very much, although the seller's claims of variable range are a bit overzealous or dubious.What I really don't understand, and what made me rate this lower, is why does the lens come with a 55mm back thread for my camera, but a 58mm forward thread for the lens cap? Could it be to make the front wider to not obstruct wide angle lenses? That doesn't matter on my nifty fifty, but what is affected is that I can't put my lens cap on with the filter in place. Luckily, I had a 58mm lens cap laying around, but you'd think that would be stated clearly in the product description. Did I miss that? So really, if you buy this lens, you need to figure out what the front thread diameter is, and factor in the purchase and hassle of an additional lens cap if you're going to be using this a lot.

This is a great product. It allows me to play with different levels of ND without having to switch multiple filters. The item does have a star-like area, but that spot is beyond the max / before the min indicator. As long as you pay attention to where the min and max are, this item works perfect.

Came on time. Seems well constructed.The first thing I did with it was take it outside, point it towards the sky (overcast), and then took photos through the filter from min to max settings. No weird apparitions. All the photos looked good so I decided to keep it. Got some nice blurred waterfall shots and blurred Lake Superior wave shots. Got a little too close to the lake at one point, though, and ended up getting a fine spray on the filter. The water caused a white blotch on those couple of photos. Understandable. So glad it was there protecting my lens, though. LOL Anyways, I dried it and went back to shooting. I've only used the filter on my 55-200mm Nikkor lens and the days I've used it happened to be overcast. If I think about it I'll update this review when I use it with a wide angle lens and/or on a bright sunny day. The dial for adjusting the different settings is smooth and easy to use. Didn't have any problems screwing it on or off my lens. I really appreciate the nice nylon pouch for carrying it in my camera bag. I'm an amateur photographer obsessed with photography. I can't afford to buy high end equipment, but I strive to go with the best I can afford. I am very happy with this filter.
