I bought the gradient filter because it was recommended to me by friends.

After a few weeks of use I can say that I am more than satisfied with it.
When taking photos, it is necessary to darken the sky (e.g. at sunrise or sunset) in order not to get a burned-out sky or too dark a foreground.
This is where the filter shows its strengths. The filter can be positioned very easily in the appropriate holder without the risk of it slipping out. This gives you beautiful photos even with long exposures.

To expand, I will add more filters of this brand later.

I can make a clear purchase recommendation!

“The marker on the side of ND2 – ND32 is fixed so you can't walk past it and accidentally see a cross on your video.

It's a must have in your camera bag and at a fraction of the cost of other brands of variable ND filters.

Delivery - Fast, timely and safe packaging. The filter has its own box, so you can safely go out into the wild for photography.

Have you ever tried photographing water in direct sunlight? You pass the waterfall and you want to take a great photo, but due to too much brightness your options are limited - believe this has happened to me several times, but with the K&F Concept ND filter the problem is solved. I'm an amatUKr photographer who loves spending time in nature and I think ND filter is something you need to have in your gear ASAP.

Being able to adjust how much the filter should be closed and thus get a darker filter is a great thing.

The filter is mounted directly on the lens, simply throw it back (note the size of the lens!). You can still take it, it's not difficult and you get great effects with it!

Long exposures without an ND filter are a nightmare and having ND filters in your pocket will be an amazing thing.

Another thing I would recommend is the mobile app (there are more - just try it) to calculate the shutter speed with the ND filter. You can find the formula on the web, but we need to use the technology correctly.

I can warmly recommend K&F Concept Filter!

1. When you run it on your camera, your little flashes will be very powerful.
2. I used it for a 30 second exposure at max ND and found that the x was in the frame. maximum darkness.
3. I buy everything else from K&F. The quality of this tool is perfect for me as a professional photographer. It even comes with a circular case that you can slip in your bag when you don't need it.
4. It's also great for the lens when using your DSLR for video work!

I have a Sony A7III with some of the Tamron lenses they recently released, 67mm thread on the dUKx. I first used the ND on a daylight midday shoot and was amazed by the results. The best part is that I can choose the number of stops I need to make the zebras disappear with ease. Ease of movement and robust construction. Only negative is that the sun visors don't fit after turning on the ND. Not a deal breaker but be aware.

EDIT: I also took it on a trip to Lake Tahoe and it came in really handy for longer exposures and more sky contrast. Awesome and so easy to use!

Perfect for my needs.
I shoot a lot of outdoor videos and since I can't change my shutter speed, photos tend to be overexposed if I leave my aperture wide open.
I have used this Nd filter from minimum to maximum and the image is still clear and sharp.
Fits perfectly with my Sony 24-70g Master

An ND filter that keeps what it promises. As soon as you unpack it, you notice that great value was placed on high quality. The transport cover is already very neatly worked and thus ensures safe transport of the filter. The filter itself is really well made. As soon as you unscrew it, you can tell that everything feels really good. The metal ring is a bit frosted, which ensures a great grip, especially when adjusting. Adjusting between ND 2-32 works seamlessly and is really smooth. Absolutely jerk-free but also heavy enough that nothing changes so quickly.When adjusting it yourself, you don't notice any disturbing influences such as the typical cross, which was often the case with variable ND filters.The value from ND 2 to ND 32 is also perfect for the most long exposures. This ND filter is perfect when it comes to sunsets or the typical smoothing of water. In addition, the filter is nano-coated so that water droplets roll off directly and the filter cannot fog up in the first place. What was important to me was that the filter is not so thick and heavy. This is where the K&F Concept ND Filter really shines. It is almost as thin and narrow as a normal UV filter. A feature that I like very much. Since the filter starts at ND-2, you wouldn't have to write it off even with normal photos and can vary very quickly. After my first tests, I have to say I wouldn't want to be without this filter in my camera bag anymore. In addition, the filter is nano-coated so that water droplets roll off directly and the filter cannot fog up in the first place.

This is my first square filter! The first thing that struck me was the very elegant and practical packaging - the ring that takes the filter out of the storage box is very clever.

Far exceeds expectations. Quality of packaging matches a much more expensive purchase. The visual quality of the filter is equally top-notch. After using the filter in my filter holder, I can't see any evidence of color cast or filter clarity. Overall, I have nothing but great things to say about this offering. Will definitely look to this manufacturer for future filter purchases.
