K&F Concept 52mm ND Fader Variable Neutral Density Filter ND2 to ND400 for Camera Lens Ultra-Slim, Multi Coated

Good filter for the price they ask. Using mostly for videos.

For the price, this is the best VND. Shifts color slightly but nothing that cannot be fixed in post. Only problem is that it works upto 8.5 stops. Still gives me a 2.8 aperture shutter 50 in UAE’s harsh midday sun. Unlike others who commented, my filter sits properly with the markings on the top on Sigma 24-70 f2.8.

Perfect for me.Does the job well.

I’m not satisfied with the qualityIt creates a huge vignette and also X effect

I don't think there is anything at this price that is that good. I have to be honest, I have not used any other variable ND filter but this one is amazing, super clear and no fading of colours. Great product and will recommend it to others.

I tried it on 70-200mm lens it was fine however in my 24mm lense while change the intensity in ND filter (ND 8 to 10) you can see a dark croas forming on the filter instead of making the whole scene dark.

I don’t recommend buying this ND filter. Would be better if you invested into something more expensive but better quality. This filter did a lot of vignetting on my videos and it also moves a lot because it doesn’t have hard stops. Unfortunately had to return it.

So on the corners it have vegniet and its just destroyed the footage

I used it for photo and video and it works great. Sometimes I have some vignette to my images but I kinda like the style of it.

usado en cámara pentaxk50 con objetivo 35mm y adaptado con aros ajustables, en los niveles 8/9 se muestra la cruz viñeteada, así que, trabaja bien en el resto cumpliendo con la reducción de luz.

Quality is ok, but there's a minute hairline scratch on the edge. But not noticeable while firing a shot or even after, so I choose to go with it without a replacement. So be careful by thoroughly checking yours.

No complaints at all with this filter - feels smooth and solid, no noticeable impact to quality, and no weird X pattern. Amazing for the price.

It feels sturdy and well made. Clear crystal and it is variable so you can adjust the filter accordingly to your needs. I am using it on a Sony Alpha 6100 with a 17-55 mm lens, it fits perfectly. It’s worth it for the money considering other brands you will find.No complaints, quality is great and it does what it is supposed to.
