Using on a sony rx100 mk7 with jjc adaptor.....no vinetting on the corners. Filter works a dream. Adjustable nd has a start and stop point....it doesnt continually turn. Excellent product

This variable filter is great. It gives a little extra length of time at dawn or dusk to smooth out motion. I had no issues with vignetting or the cross effect I've had with a rival brand on a wide angle lens. This could be because the filter is wider than the fitting thread on the front, or could just be down to a good quality piece of glass. Either way, I'm very happy to have it in my bag. The case is robust but easy to open, and the glass is easy to clean.

Good filter quality, no vignette when turning all the way to ND32. Would recommend!

Nicely made, nicely damped movement. And none of the X vignetting that happens with some variable ND filters.
and if you unscrew it slightly works well as a polarising filter which is a nice unexpected bonus!

I have used other variable ND filters in the past and whilst I didn't ever come across any real issues with them, I did brake my last one when dropping it in a car park!! So I bought this one having already been very impressed with the K&F square filter kit, I thought I would try them again and they haven't disappointed. I mostly use the VND filter when filming (the square kit is not ideal for filming) and in the summer it's a must-have piece of kit. The case that comes with the filter is really handy for chucking in a bag and I know it will be protected. the twisting rings are nice and chunky so its really easy to change the strength which is hand when filming.
The image quality is great with no noticeable colour casting and you don't get the wired X that you can sometimes get with the cheaper VNDs.
With a VND at this quality and price point, I really see no need to invest £300 in one.
My only very slight gripe is that I cant use my lens hood with it and the lens cap doesn't fit as snuggly as it does on the lens, meaning I cant just leave it on.

Bought for my Fuji XA5 with the kit lens. Very easy to use, just screws on and comes in a portable container. Used it quite extensively over the weekend shooting long exposure of waterfalls in daylight, worked like a charm.

in pI’m always dubious when it comes to filters as I have seen some cheap ones in that past that really degrade image quality. This neutral density film seems really good though.

It seems well made and screws on nicely on my canon EF-M lenses. The twisting adjuster works easily and smoothy and has the various stops marked on it.

Performance is really good too. There doesn’t seem to be a vignette or any other visible marks or patches on photos. The photos seem to be just as sharp and have the same quality as when shooting without the filter. I can’t tell any difference. It comes in a nice holder although this is way bigger then the filter itself.

The range of stops on the filter is good too and helps to slow things down for some major motion blur. It also works well for open aperture video. For the price I am really impressed with the quality and results.ast i got k&f ND filters and i wasn’t happy about them because the had horrible purple colour cast what i couldn’t get ride with photoshop, they were cheap. about £10 for 3 different ND filters with pouch. yeah... price does matter))) lol)) this one is NOTHING close to those what i use to have. it feels like i had ford ka and now i have ford mustang)))
ok...
i use 70-200mm is f4 and 10-18mm both have 67mm
it’s really easy to change from ND2 to ND32 don’t need to unscrew your ND filter from lens, just spin the circle.
there is NO COLOUR CAST. what is most important thing in ND filter. i would say i bought Nisi quality ND filter for twice less than Nisi.
comes in hard storage case not pouch. so when you throw your ND filter in your camera bag , you don’t have to worry about that it will smash. i would definitely buy it again.

Great tool for making sunny conditions usable with a high aperture making pictures completely over exposed, this fixed that. Also it’s quite good to have on the camera as a kind of protecter of the lense.

Very well engineered filter, with a decent price. Being able to adjust the degree of neutral density without changing to another filter is a very useful feature. It reduces the number of filters to be carried, which in turn reduces the overall cost for a wide range of filters.
My only problem with the latest ultra-slim filters is that they’re a bit too slim when it comes to changing the filter for something else. All things considered I am more than happy to recommend this filter.

Variable ND filters are fairly new on the market. They have various uses like showing down water to give it a smooth effect, or if shooting in bright light can help reduce exposure.

This filter comes nicely packed in a box and then inside a round plastic case. The filter feels heavy and this gives it a premium feel. By adjusting the filter you can control the exposure, unlike a fixed ND filter. I’ve included a shot taken with it of a sunflower which was over exposing due to the bright sunlight. This filter allowed me to get the sunflower at the correct exposure.

Trying to get a shallow depth of field in bright light is often difficult but this filter solved this easily. It doesn’t alter the image quality unlike cheaper ND filters.

I can’t wait to get out and use this more.
