KV37 67mm Fader Variable Adjustable ND Filter ND2-ND400 - Ultra-Slim & Multi-Coated Nano-Klear
SKU: KF01.1390
This one helps to keep colors true.
Have you ever tried to photograph purple sport’s uniforms? Without this filter, they often come of digitally as navy-blue uniforms. This filter is a problem solver.
Ever photograph polar bears in the snow? This filter helps keep all the shades of white clear and precise.
I label each box with what to expect from the filter.
It makes it easy to grab and go with the correct filter.
However, when I have time, I enjoy changing out the filters and shooting the same scenes with different filters. It often yields unexpected and lovely results.
Essential filter. Well worth the time and expense.

I'm really super satisfied with the K&F Concept ND filter, it looks high quality, price-performance is great and I've been able to use it many times. Thanks to the scaling on the outside, the permeability can be adjusted very well.
Gladly again

Variable ND filters are not recommended very often. There's the argument that the darkening range is too small, that it's more universal with a square filter that you can put in front of any object using an adapter... And finally, there's the argument that they often have a slight color cast. Which cannot be dismissed out of hand with these. I noticed a very, very slight green tinge.
Variable ND filters were developed for filming, because the lighting conditions change frequently and can be adjusted very quickly by rotating them. The slight color cast can be quickly removed in image processing. I find these filters good for my purposes, because I can experiment with the different darkenings due to the variability, the filters are inexpensive. I bought them for my most important lenses. Not only are they good for long exposures, but also when it's very sunny. By using them, I can achieve longer exposure times. This also applies to portraits. These filters can be easily screwed into the thread and - what is really important - also unscrewed again. Anyway, I'm looking forward to the first long exposures with it.
I've also heard that the screw filters can cause vignetting. These are also easy to remove with image editing. Moreover, they are even "modern" at the moment.
The filters now accompany me in my first steps in the field of long exposures. If I feel more professional, maybe my equipment will become more perfect. Now, however, I look forward to working with them.

This K&F Concept variable ND filter is to product that does not disappoint the photoamateur and based on the price paid, the top rating is fully earned. Needless to say, it is not comparable to high-end ND filters.
The only weakness, as pointed out in other reviews, is that it has no start and end point, so the dial spins endlessly. However, the problem does not exist for landscape shots where you have plenty of time to check the correct filter setting.
Vignetting appears only below 24mm, instead the cross only at the last stop in precarious lighting conditions. Colors are vibrant and not altered, color dominance is minor and for the perfectionists it can be resolved in raw in post production.
The following photos were taken with the highest stop, only the night one was taken with lower stops.
Qualities:
- very good materials
- very good finish
- perfect threading
- colors are vivid
- color dominance is minor
- top cost/performance ratio
Flaws:
- it does not have end stops
- vignette under 24mm
- cross only at the 'last stop with precarious light
Rated, based on price, 100/100

I bought this filter tempted by the derisory price and the fact that it is small lightweight and that it allows me in one accessory to have several plates together, as I already have plate filters and moreover 150x150, which are really inconvenient to carry around .
The product looks really good packed inside its case, it is very light and of metallic material with the various notches indicating the ND set. Maybe on this one I would have liked it to actually say how many stops you were at without me having to do the math every time to figure out how many NDs I was at.(but maybe space doesn't allow for that).
I am happy with the purchase I made because it exceeded my expectations,
I tried it with focal length above 50mm where I didn't find any problem and the image turns out with uniform exposure without any halo, it must be said though that I also tried it only at ND400 without trying the intermediate stops so I couldn't tell what happens at lower stops; Unfortunately being in full daylight didn't allow me to do other tests..(of course if I can I will update by adding some more details).
Finally I think that in terms of quality/price there is no better around, at least for the ones I have tried and K&F improves year after year...
I enclose a few photos to make yourself aware of the product and the result....

I shoot a lot of video with my Canon, and to get that cinematic 180º effect with the shutter speed, I often have to reduce the amount of light coming in when shooting at 30fps. This is where the ND filter comes into play.
In this case I am still starting but it is difficult to know which way I have to turn, I would like the filter itself to have a stop to indicate me the maximum or minimum.
Otherwise, this filter does not produce any distortion like some filters I have seen in some tutorials, nor dark halos. A great buy, if you are going to use it with different lenses, I recommend to buy some rings to adapt it.

Well packaged and delivered the third day. The K&F Concept filter itself feels to be of good built quality with a metal frame holding the glasses in place. The action to adjust the stops is smooth. I bought this mostly to save some bag space so I'm not having to either stack and carry multiple ND filters.
Considering the price, the image quality is reasonable. I did not experience the dreaded X from the graduated filter. You can see some product and test images I did at home to test the product. ( the camera settings remained the same throughout the test images with adjustment on just the ND settings).
