This filter is adjustable. So, one filter can take the place of many. So far, it is working very well for me as well as saving me some space and weight in my camera bag.

Very nice filter. Seems to be no difference in image quality. I attached an image I got with the filter attached. It is fitted over a hoya UV filter as well.The lens rotates smoothly and has marks so you know with you are at the min or max.It’s nice to have one on your lens for outdoor shoots so you don’t have to keep swapping out different filters with lighting changes.

Does the job nicely...

you don't need any other. great price for a great filter.

I wanted a filter solution for my Osmo Action and with the right case that can take up 52mm filters. This filter works as intended, it's not a top quality filter but then I did not expect it to be. It definitely does the job and no complaints. Worth it? Definitely.

I really like that the filter is adjustable. I don't have to worry about removing and replacing during a photoshoot. Looking forward to using it more frequently.

Darken well but add too much color shift into the blue - gray hues. Will require a lot of post color correction or constant white balance in the field every time the darkness is changed.

love this item. It's a life saver shooting on a sunny day. For some reason though the glass has gotten small scratches in it from only about 2 uses.

Excellent nd filter. Crystal clarity and has a very smooth function. Exactly what I wanted to lower my exposure for waterfall shots and light trails.

This filter definitely works as advertised. I researched exhaustively and checked many reviews before purchasing.Comes in a nice plastic box with some foam cushioning; I added a layer of thin foam in there to keep it from moving around in my bag.I'm in Florida - took this outside mid-morning, full noon and afternoon, and on an overcast day. Outstanding results, including with flash. On sunniest days I did not crank it up to the maximum setting, just below, and still got great results for both stills and video.Shooting on a a Canon 6DMII, got three lenses that'll take this 52mm.Not a 'pro' but half of my income comes from photography and video.Would definitely recommend this filter - I feel kind of dumb not having gotten it years ago, could have saved many shots.I found this after seeing the versatility of a variable ND demonstrated in a video, realized I must be missing something. When I looked up that item I was astounded to see that the low-end for that series prices about $250/$300. If you're making museum or some kind of major publishing landscape images you probably don't think twice about that, and I'm certain those pieces are quality. However, if you're reading this then you've already come across a couple of childish and self-important remarks about how this item doesn't compare to 'pro' or 'real' filters. You're on Amazon here - this thing works, give it a try.Finally - have seen a string of reviews with tantrum-like rants insisting that this filter doesn't work and puts an 'X' on the image.I'm guessing that's true ... because in the little page that comes with the filter (and the description online) it's clearly stated that turning the filter up to it's highest setting will create this artifact, so they kind of advise you not to do that.Also, if you cross the street on a red light, you will likely get run over.It's working for me!
