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

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.

I've had variable filters in the past, but I've never been satisfied with the dreaded X's on the screen when spinning or the uneven color cast across the screen, and these are great, very even light reduction across the frame and no X's. I have the 77mm filter, it is very well made, 77mm so no vignetting in the corners, the slight downside with it is that I can't fit the filter with my armour, but no big deal. We recommend.

Brilliant for the price though you do go a bit heavy with these, but is still nice

I love this 77mm ND filter which fits perfectly with my Nikon 70-200 f2.8. I use step-up rings for other lenses like my 85mm f1.4. The ease of use is phenomenal and it glides so effortlessly. I love this filter. I would recommend it to anyone to cloud it down to the darkest, open the aperture wide and take a long exposure during the day for amazing results. New!

ND filters are essential for some types of photography, such as moving vane effects - and as I suspect I am exaggerating litt.... And of course there are millions to buy and a huge range of costs. I've tried lots from super cheap kinesium resin to some anstendig quality, and reach this. First and foremost is optical glass. And that makes a difference because the resin type, while not bad if you treat it with extreme care, tends to rip easily, and of course the optical quality regardless of what the text says is not nearly as good as anstendig glass. On the other hand, it is very well made. I mean up there with the silly prices well made as I have tried and used in a well known camera store. This is a true 100% premium set considering the production standard and the overall feel of it. Smooth in action with perfect optical clarity across the density range. In use it is super simple. Fit - which is smoothly given to the well-made thread and then rotates the outer ring to the desired level of darkness. It saves a lot of time with different filters or stacking of them. Frankly, if you want a good selection of ND filters (not outdoors of course), this is a good choice. I used it on my Zeis Batis lens, and it worked a treat.

Works great when you start long exposure, but has litt vignetting and color sharpness

I ordered this filter for my Canon 800d and it works like a charm. The packaging it came in gives you an idea of the product's premium execution. Since this is a variable Nd filter I can leave it on my lens as the filter does not have to be removed to get more light. I had high expectations for this filter while ordering, and the results are better than my expectations. The filter ring is very smooth and does not shake when shooting video. There were no dark spots on the sides of my images as I have experienced for some other filters, Prime delivery was very quick and the product arrived safely in one day. I would definitely try other K&F Concept products as the ND filter lives up to the claim.
