K&F Concept43mm Variable Neutral Density Lens Filter ND8-ND2000 (3-11stop) Waterproof Adjustable ND Lens Filter with 24 Multi-Layer Coatings for Camera Lens (D-Series)

I wanted to be able to shoot off camera flash without having to use HSS (high speed sync), so i did a little research and came to the conclusion that I needed an ND Filter. There are a lot of options out there but I knew the price point I was comfortable staying in and this filter was the best blend for versatility (3-11 stops) and price. I didn't see the benefit in getting an ND filter with a smaller stop range such as 3-5 or 7-11 etc. This ND filter covers the entire range in one package. And the adjustment ring feels high quality and has really good feedback when stopping down or up. I saw some people complaining about the grid pattern you get sometimes when stopping down on other ND filters, but I haven't experienced that problem. This ND filter has been nothing but perfect for me. I was able to shoot at 11 AM with with harsh light and overpower the sun with my flash for a recent shoot while staying under 1/250 sec. I definitely recommend this ND filter if you need to stop down for whatever type of photography you're into.The only issue you may have with this ND filter is trying to use a lens hood with the filter as they may not fit with one another.

It does what you would expect. The ND is nice and works well. I used with my R6 mk2 with my 35mm sigma and looked fantastic for cinematic video. I plan on buying more for future lenses. Good buy!

The media could not be loaded.  This review is for the K&F Concept 58mm ND8-2000 filter. Overall, a very nice piece of kit (especially for the price). The only downside is there is the dreaded X at the last stop or two when I shoot video. The picture is on stop 10 and there is no X. I don't expect an X in video to be a problem for me, as such an extreme setting will probably never be used. For reference, I am shooting on a Canon 90D with 24mm f/2.8 lens. Settings are 100 ISO, 24 fps, 50 shutter speed, f/2.8 aperture.

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.

Maybe there are quality control issues, but i don’t have the problems others claim with this variable ND. Slight ‘X’ at max effect in some conditions but I did not plan to use it at the extremes. A little color shift but that is to be expected. Maybe a slight softening but nothing that can’t be adjusted in post processing. I bought it primarily for video outdoors so any softness is ok.Overall, I am pleased and recommend it. If you find a problem, just have it replaces. I suppose there could be some quality-control issues. Be aware that it can get stuck to a plastic adapter ring.

Very happy with this ND filter on my Sony E 16-55mm f/2.8 G lens

Worked great, I was very pleased with the results,

I bought this and the Kodak 52mm ND filter for my Moondog Labs Anamorphic Lens and shot on my iPhone 12 Pro Max. I thought I could save $14 by settling for the cheaper Kodak ND filter but the image quality couldn't compete with the K&F one. Compared to the K&F filter, the Kodak has a greener cast, washes out colors, isn't uniform, and X-patterns A LOT earlier than the K&F Concept so the Kodak is not true ND2000. I went out on a bright day and with the Kodak filter I couldn't even get the highlights to be saved before a severe X-pattern started showing up. Locked shutter to 1/48 and ISO to as low as possible. The K&F filter also X-patterns a lot nicer too. When the K&F starts showing the X-pattern, it actually looks like a nice vignetting because it's so smooth. The Kodak filter looks too harsh like a hard X. No edge feathering (I don't know if that makes sense). I don't know how to explain it but you can buy both and see for yourself. The X is really wide and smooth on the K&F and it's even hard to tell it's X-patterning when you start reaching it's limit. Another thing I noticed is that the Kodak filter doesn't darken the entire frame. The left and right edges are brighter than the center whereas the K&F is uniform. I really wanted to like the Kodak as it comes in better packaging, but the filter just doesn't perform well. I LOVE the aluminum packing Kodak used for their filter, but the K&F Concept ND filter is the CLEAR WINNER.

Value for money，also you will have good pic or video quality. I use lumix s5,BTW

Apart from the X pattern and color fringing at the edges, a decent ND filter. given the options available, can't complain, but I am left with a desire for a better one.

Stops of lights for this ND filter is not as accurate but still the value is fine for what you are paying

Good

Photos taken at f11, 1/125, iso100.Used 2 stops and 4 stops ND ( K&F )Be the judge.
