You don't need to waste a lot of words about KF, the quality is undoubtedly outstanding. The medium filter fits in seamlessly there.

Bought this for a recent trip to Rome. Never came off the lens. terrific build quality and performance. worked silky smooth, love it!

If you take photos of sunrise or sunsets, this is the filter to use.

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.

The quality of my recordings, for which I need a gradient filter, has improved significantly with this gradient filter from K&F. Even with problematic sun shots, it reduces unpleasant lens flares. great

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.

High-quality filters, great scope of delivery.

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 is extremely clean and comes in its own bag with a magnetic closure. I didn't notice a color shift like with various other "plastic-based" products (but I don't use several filters in combination either).

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.
