ND FILTER
Reduces the amount of light entering the lens, thus decreasing camera shutter speed. Useful for situations where motion blur needs to be created (rivers, waterfalls, moving people) or large apertures must be used with flash to avoid overexposure.

"X" shape visible at ND32
Despite what's advertised, I did notice the X shape at the darkest setting, ND32. But up till ND16 the X shape isn't there and it's perfectly usable. I would even say that even at ND32 it's usable for some settings where the X wouldn't affect the image much as it's not TOO bad. The photo I've attached was actually at ND32, but the X shape isn't really noticeable.

Almost completely perfect, but some X at ND64 at 16mm.
Virtually perfect consistency of brightness at all focal lengths except very wide.notice noticed X at around ND32 and above at 16mm focal length. At 24mm X appears closer to 64, by 28mm X still faint but apparent at ND64, at 35mm all ND values are completely X free (subjectively - i did peep, but i didn't use any analytical tools to objectively verify ZERO variance in brightness caused by the filter, however, with close examination I failed to see any inconsistencies below ND32 at any focal length, and all focal lengths above 35mm are completely "X" free. All focal lengths 16mm + are usable at ND32 or lesser.All and all its an outstanding variable ND. Its clear and crisp and highly functional. This filter does not degrade contrast or resolution as some variable NDs are prone to do - this is highly functional and a great value. My only advice would be to test out all your lenses on your largest sensor body to find out when and if any artefacts appear so you know what, if any, your limitations are.I found that the X was quickly noticeable - at say ND32 it may be a question as to whether its there or not, but by say ND36 it would be clearly apparent. This is a great filter, but especially with wide angle lenses you should test the water so you know before a bunch of images turn up with artefacts too subtle to see on the display in full sun, but treacherouslu obvious on a display or a print...

Great Product, Great Customer Service
I've had this filter for almost a year now and it's been a great tool for my outdoor filmmaking. Solid product and when I needed some support, K&F's customer service was incredibly fast! Will definitely be buying more K&F products!

Excellent ND
I have only ever used this variable ND. I have no experience with a more expensive or higher quality ND filter. WITH THAT SAID... I have nothing but good things to say about this ND. As a full-time videographer, I love using this ND when I'm shooting outside. makes getting a good exposure very easy. there is a clear vignetting when it is very bright outside. i recommend this overall.

55mm, but if I was you I would get a bigger filter and use step down rings to fit the size you need. Like the Tamron lenses are 67mm other nice Sony are 67mm & 82mm so I would get 82mm and use step down rings. That’s just me

multi-coated layers,different frame thickness and so on.

this one has better nano coating layer and it has no X cross on images when adjusting to the max stop, while the k&f nd2-400 don't.
