Quality filter, there are 5 steps, it is convenient for sunny days, it comes with a leather case with a magnet to close it, the filter is made of glass and not resin, the quality and price are luxury, I have more expensive filters from other brands and they are worse.

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-term exposures. This ND filter is perfect when it comes to sunsets or the typical straightening 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. Which is still 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.

Absolutely amazing filters and a great price for glass, no color cast that I can see on any of my support images.

The filter looks valuable and the packaging is good. Unfortunately, my copy showed clear vignettes in both the direction of ND32 and ND2, making the filter virtually unusable. In addition, the minimum stop was not clean, so that a clear darkening was already visible at minimum (>ND2), only turned a little further did I actually have ND2. So it went from slightly darkened (>ND2) to bright (ND2) to significantly darkened (ND32). It's a shame, but that's why I sent the filter back. I then did not examine the glass quality more closely.

Works great if you're starting out with long exposure photography, but has a bit of vignetting and color cast

For auto rigshots I needed a quality filter at a good price, this would be worth buying at a much higher price! It comes beautifully packaged with a high quality holder for the filter, all made from non-animal products! But none of this matters if it doesn't work, but it does! High quality glass with no tolerable impact on my A7R IV's picture quality. If you need a great ND, this is it!

The filter comes in a very elegant packaging with a magnetic closure and also has a small plastic box for transport. The filter can be easily screwed on and off the lens , estimated at the maximum setting 3-4 full f-stops. You can see the effect best in backlight or strong contrasts in the subject, I'm looking forward to testing the filter in the midday sun in summer.

The filter came as described at a good price, the packaging is very valuable. I can't say anything about the quality here because I've only tried it once and the pictures aren't available yet. However, the handling was great.

As a photographer I'm always looking for ways to save weight, then save money. Being a longtime Lee Filters user I was skeptical about changing to a product half the price and always heard bad things about circular variable ND's. Man I was shocked by how good this product is. Really happy and will be buying more.

Good product, good seller and fast shipping. I would recommend this product to anyone who wants a good bang for their buck ND filter
