KV37 58mm Fader Variable Adjustable ND Filter ND2-ND400 - Ultra-Slim & Multi-Coated Nano-Klear
SKU: KF01.1388
This is a product I chose after reading the reviews. It is highly recommended for beginner photographers. The adjustable function is definitely.
I took several photos with and without the filter and made various adjustments to the filter and I can see the improvements in the results.

Good filter for the price. I'm not a pro or any expert but I only needed it outdoors for my DSLR. It does the trick.

What a treat to spend so little and get so much. Not only does this filter work exceptionally well, the workmanship and packaging is first class. 3x worth the price. Coincidentally, I bought a Tiffen filter in the same order. Your filter was sliding around in its housing and needed a thorough cleaning before I could use it. Not so with K&F. Untouched and ready to use. Well done K&F.

K&F Concept 49mm ND2-400 (1-9 Stop) Variable ND Filter Slim Variable Gray Filter Neutral Gray Filter
These filters are wonderful with ideal cinematic qualities. Most importantly, you get a product with superior build quality and looks at a lower price than other brands. HiShop is a very professional organization and I plan to return to this provider in the future.

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

Bought hoping to solve the need to stack filters and it's better than that! It solves the infinite spinning of the filter. With most variable ND filters, you just keep spinning and you end up with those dark X-shapes and other problems. This filter has markers and a lever that stops at either end of the variable nd, meaning you don't go too far and ruin your recording. It's the best image quality in a filter (probably not), but it's not $3-400 either. So it's a killer for value

Definitely a nice surprise! I expected an average filter for the price, I'm attaching a copy of one of the first 5 photos I took with it in the Smoky Mountains. The first 4 just figured out the shutter speed I wanted. Very satisfied, wife happy - couldn't ask for more. I look forward to many images with this 82mm variable ND filter with my Tamron 24-70 lens (or a wide angle lens if I can afford one) on my Nikon D-500.

Here in Arizona we have 320 days of sunshine a year. The sun is bright and intense. An ND filter is pretty much a must if you want to control the quality of the recorded video. This particular variable ND filter works well on my Fuji X-T4. It allows me to set my lens at f4 and keep the exposure perfect. Setting the lens to f4 means it's in the sweet zone of sharpness, producing great videos. It's a great ND filter for the money spent.

It can be turned with a slight resistance, so that you cannot adjust it accidentally. In addition, it feels very high quality.

I was surprised at how good this under $20 Vari filter turned out to be! I needed a Vari-nd for my trip to Thailand as I only had one lens with me (Blackmagic Pocket Cinema with a Panasonic 20mm 1.7). I usually use the Hoya ProND (one of the very best ND filters ever) but I needed something more practical for a vacation as wearing NDs wouldn't be. Looking at the footage I shot I'm very glad I decided to purchase it as I haven't noticed any toning yet (despite shooting raw). Remember that there is a rainbow effect behind certain glass surfaces.
