I'm a Professional and I've had 100's of lens filters over the span of a 30 year career. K&F ND Filter is as good as my highend, high priced glass at a very affordable price. As many are buying cameras that shoot both stills and video and you're looking for an ND but aren't sure what to buy... you will be very happy with K&F ND Filters.

Very happy with this purchase. I love the fact that it is variable giving me more control in one filter. It ses to be made of good quality and as the K&F Concept CPL filter I bought, it is definitely great value for the quality and your wallet if you are looking for a great mid-ish grade filter. Happy purchaser :)

I've used it once and I paired it with a 10 stop ND filter with this and I was able to set my camera set at 30 seconds, f11 and ISO 50 in the middle of the day but with the 10 stop I could only get it to 10 seconds, f11, ISO 50. I was surprised to see that when I got home to edit the photos there was no noticeable loss in sharpness with both ND filters on and this being a variable ND filter they're notoriously known to be less sharp than a constant ND filter. I can't wait to test this out on a waterfall but being that it's summer in San Diego right now I'll have to wait to try it out but along the coast I prefer the 10 stop ND filter and being able to drag that shutter longer. The front of this variable ND filter is quite large so your lens hood won't fit on there which can be an issue with unwanted lens flares but the K&F 10 stop ND filter I used with this you're able to mount the lens hood still. I received this filter free of charge to test it out so take my review with a grain of salt but if you do choose to get this I highly recommend getting a 10 stop as well because you'll be limited to 2-3 second shutter speeds with this alone at it's darkest setting in the middle of the day where the sun is bright like it is here in Southern California. I forgot to mention that there are notches on the side and tells you the minimum - maximum darkness and each stop between so there isn't any guess work involved but I do like the fact that I was able to set my settings I wanted and just rotated the front element until my camera read that I was properly exposed.

Its great quality dynamic range all in one ND filter, perfect fit on Nikon D750. It adds great value in Natural Photography by adding dramatic effects through controlling light intensity from low to higher or higher to low range with just one filter being installed on the lens.

Just tell you about my experience:I bought a 82mm variable ND filter + step-up adapter for 55mm ultra wide angle Canon EF M 11-22.It’s a good lens but I just to list my issue under my condition:1) There are black shadows on the edge of photo for wide angle.2) Too heavy for a camera gimbal to get balance.3) There is no locking point for adjust lens. There will be black cross show up in lens after Max point.I know buy one 82mm ND filter plus step-up adaptor could be economic way. But I prefer to buy right ND filter for the right lens.

To be honest I’ve never had an expensive variable nd filter to compare to but I’m very happy with the results. Haven’t really noticed any massive colour shifts (I usually colour grade my footage to taste anyway
