Bought this for a recent trip to Rome. Never got off the lens. good build quality and performance. worked silky soft, love it!

I use the filter both for filming with DSLR and for long-term exposure during the day with an open aperture, especially when filming, it is simply beautiful with an open aperture. The ring can be easily turned. The sound should be recorded externally, because the ring clicks quietly in the intended positions .. The packaging is great for transport and can withstand the attacks of my 1 year old daughter. The image quality looks good. At least I could not see any tint or other disturbances. I am very happy with the ND filter.

Good product, good seller and fast delivery. I would recommend this product to anyone looking for a good value for money

First time using an ND filter. Really good quality, none of the issues I've read about with cheap ND filters highly recommended

ND filters are essential for some types of photography, such as moving water effects - and which I suspect I exaggerate a bit .... And of course there are millions to buy and a wide range of costs. I have tried lots from super cheap kinesium resin to some decent quality and now this. First and foremost, it's optical glass. And it makes a difference because the type of resin, although not bad if you treat it with the utmost care, tends to scratch easily, and of course the optical quality no matter what the text says is nowhere near as good as decent glass. Secondly, it is very well made. I mean up there with the stupid prices well made that I have tried and used in a well known camera store. This is a real 100% first class set considering the production standard and the general feel of it. Smooth in action with perfect optical clarity across the density range. In use it is super easy. Fit - which is smooth given the well-made thread and then rotates the outer ring to the desired level of darkness. It saves a lot of nonsense with different filters or stacking them. Honestly, if you want a good selection of ND filters (not graduated of course), then this is a good choice. I used it on my Zeis Batis lens and it worked a treat.

Brilliant for the price even if you make it a little soft with these, but is still great

As described, the filter came at a good price, the packaging is very valuable. I can not say anything about the quality here, because I have tried it out and the pictures are not available yet. However, the handling was excellent.

So good i brought 2 as I often have 2 cameras with me when im on shoots, perfect no cross easy to use

Hard work to use as viewing thru the viewfinder is very dark, you could compose your picture wiithout the filter first, but you run the risk of dropping and breaking the filter whilst trying to screw the filter in. In hindsight a drop in filter would be more useful as you could compose first then just drop the filter in to take your shot. The image quality is good and it does the job, the filter is well made and packed complete with a nice storage case to protect whilst not in use I am pleased with it.

I did a lot of research and watching videos etc before buying the K&F veriable ND filter, I wasn't sure this filter would help with 4k video, wow was I so wrong. As you can see in the screen shots from the video, it makes a massive difference. I am very impressed and glad I bought it. Yes I would recommend. Thanks
