I occasionally carried a few individual filters with me. But it was often too time-consuming for me to mess around with it in nature. Screwing the filters on top of each other in order to get further adding gradations is fiddly. There are enough individual ND filters, but each time you had to change the filter again...

With this filter here you basically cheat the whole handling. I wasn't even aware that something like this existed. Therefore I have attached a small video so that you can see the function. Even if there is "only" ND2-32 here, you can see what these products can do.
A matter of seconds, especially for experimenting, sometimes using a different filter setting. With low filter strengths, the camera automatic is sufficient and you can see the current exposure time when adjusting the filter if ISO is fixed. In this way, soft water structures can be created in relatively bright light, or soft clouds in the sky, etc.pp. I didn't really notice scattered lights or reflections, but I work on that on the PC anyway.

The price for this product is high, but considering that this covers several filters, again not too bad. However, the general question is what kind of filter do you really need. I previously had an ND8 and an ND1000. Sometimes an ND 4000 would have been required (to safely create "deserted" objects/places).

Nevertheless, I find the concept here really innovative and practical.

The filter comes very well packaged in a box that doubles as a picture frame. The actual storage takes place in a very high-quality leather case with an "ejection strap" so that you do not have to tap your fingers into the filter disc when removing it. The filter and its mechanics are very elegantly manufactured, so the filter thread can be easily attached without scraping noises and frequent attempts to attach it screw in and loosen again with moderate force after tightening, provided the internal thread of the optics is not damaged and is of the same high quality. What is special about this (ND) filter is of course the possibility of continuously adjusting the filter grade/strength using the screwed-on brass handles, what also works very smoothly and impressively! So a filter change is largely unnecessary, a grip on the rotary ring is enough. The range in which the filter effect can be changed is enormous. As an example: Aperture 13 to aperture 5.6 with the same exposure time or with a constant aperture, the exposure time changes from about 1/4000s to 1/320s. This saves a few filters and enables fine and simple adjustment to the desired effect! In combination with the K&F quality of the Nano-x Pro series, the price is also put into perspective. Personally, I am definitely enthusiastic, I have never had so much fun with a filter ... This saves a few filters and enables fine and simple adjustment to the desired effect!

A circular polarizer is one of the best filters you can own. It allows you to block light that falls perpendicular to your lens. And with a circular polarizer, you can easily rotate it to reduce or remove reflections and glare — or dim the brightness of the sky.

It also comes with an attractive pouch for storage.

This is a nice design. It's a small shape which I prefer. It turns smoothly. And most importantly, it doesn't degrade the picture.

If you're used to cheap $10 filters just to protect your lens, the price is certainly eye candy.

But this is a quality filter from top to bottom. I usually ignore the packaging aesthetic, but that's the first thing that caught my eye. I thought there was a clock in there. From the box to the filter bag - quality. They even threw in a cleaning cloth. Usually you are alone with this.

As for the filter itself, there is a noticeable difference in detail compared to my cheap filters. The filter itself is textured and grooved to reduce the need for a filter wrench. The glass even rotates inside the ring so you don't over-tighten it. The 67 thread covers a wide range of lenses I have, but I'll be using this for landscapes. A small issue with this is that the filter doesn't have much depth, so my lens cap doesn't securely attach and eventually pop off.

Still one of the best filters out there.

This is a really really nice CPL filter. It has a very slim design, so there is no vignetting even when using a long telephoto lens.

Threads it onto my lens with no problems.

Polarizer adjustment is smooth and predictable.

There is no color shift or other artifacts through the filter. Just razor-sharp images with accurate colors.

The filter comes in a beautiful fabric storage box along with a microfiber cleaning cloth.

There is also a small instruction card that describes how to use the box the filter came in as a photo frame. A bit cheesy but whatever. I just threw it away.

great quality

Hello, you have to give K&F one thing, the design of the filter and the bag as well as the workmanship are 1A and I couldn't find anything particularly negative on the test images, but I still only give 2 stars. Why? 1. In my opinion, the variable gray filter ND 2-32 is poorly chosen and insufficient in terms of gradation. Many who work with gray filters use ND 8, ND64 and ND1000, for example, in order to be able to really carry out a long exposure to smooth water or people to make the moving images disappear and that is not possible or only possible to a very limited extent with the gradations from ND2 to ND32 selected here.2. The price, K&F is asking 280 euros at the moment and for this money you get a really good plug-in filter system with various filter plates incl. POL filter or a magnetic round filter system. Such systems then usually fit the entire range of lenses from 82mm screw thread onwards, while these filters only fit 67mm lenses and with a step-down ring also on smaller lenses but not on larger ones.3. For the price, it would have been desirable if you had haptic feedback on the 5 levels when you reached a level, but the filter turns buttery soft, which is very pleasant from start to finish. Conclusion: For whom can I recommend the filter? Actually only for people who don't know what to do with their money, who only have lenses with a 67mm screw thread and are too lazy to buy normal screw filters in several strengths and then change them depending on the requirement.

I was always of the opinion that a cheap filter set is sufficient. After this filter, my opinion completely changed. The quality of the filter is excellent. I really didn't think that was possible. You might notice - I'm totally blown away by this filter... It's top-notch quality and workmanship. The controller is made of metal and here alone you can tell how good the processing is.

Furthermore, one must consider that the photo quality is influenced by filters. This is not the case with the K&F filter! The highlight here is that I don't need umpteen different interchangeable filters, but can always adjust them directly to the respective situation. Personally, I still miss the stronger gradations up to 10 apertures. However, I am really so enthusiastic about this filter that I will see if this filter is also available in a gradation of 6-10 f-stops. I would buy it in any case, even though I've worked with cheap filters for around 50 EUR so far. Quality comes at a price and in this case it does! But here you really get something for your price.

By the way, the filter fits well on the lens and I'm not afraid that I would lose it. The handling is very simple. The gray filter comes in a nice bag and is therefore very well protected.

Is a polarizing filter the same as a polarizing filter? No, that is not so. Polarizing filters polarize to a greater or lesser extent. That shows you the price you pay for it. But there are other things too: A really good filter does not have a light metal frame, because this could twist under pressure when screwing in and the filter could seize up. This polarizing filter has a heavy and precisely made brass mount, the rotary ring to bring the polarizing filter into the right position runs smoothly and smoothly. Additional corrugations on the socket prevent fingers from slipping when turning. This is also bitterly necessary, because the filter is designed as a "slim version" with a very short overall width in order to also be suitable for wide angles.

The filter's coating looks impressive and I'm happy to believe that it's particularly effective at preventing reflections (although this could only really be proven in a comparative test). The polarization effect is very good and there is no color deviation in Lightroom.

I have never owned a photographic filter that was so elaborately packaged - yes, almost "staged" - like this professional filter from the Chinese manufacturer Shenzen Zhuo Er. With this, the manufacturer wants to underscore its claim of being at the forefront of the market segment. I take it for granted that he can do that. In terms of manufacturing quality, the filter easily reaches every Heliopan or Rodenstock filter. Of course, it also costs accordingly. I'll be happy to buy a few more filters of this type - I've got a taste for them now.

Do you automatically make better pictures by using such an expensive filter? Definitely not. If you were previously satisfied with your image results, this filter will not open up a "completely new world" to you. But if you're eager for every technical possibility to improve quality, then, yes, you should really consider switching to these fantastic filters.

Although I have a filter of the same brand that works correctly, the light and contrast cannot be changed. This filter allows, albeit subtly, to gently rotate the lens once attached, altering the perception of the image in terms of light, contrast and colour. This isn't a change with a lot of variation, but you can easily retouch the intensity with which an image is captured.
You might rate it negatively because of the price, but in my opinion it's a personal and relative assessment.
The quality is very good and does its job perfectly.
