I like this ND filter a lot.

I am obsessed with this filter. The fact that it’s an all in one just got me. I use it on my 50mm lens on my Canon R6 and my pictures turn out so crisp! I love that I don’t have to unscrew it to put a different one on — just twist and you’re good! Very impressed with this.

I recently ordered the K&F Concept 62mm ND Lens Filter for my photography needs and have been extremely impressed with its performance. The 28 multi-coated circular polarizing and neutral density filter is a game changer, allowing me to capture high-quality images with greater control over the lighting.

One of the things I love most about this lens filter is its versatility. The 2-6 stop range allows me to adjust the exposure as needed, and the polarizing effect helps to reduce reflections and increase contrast. The 62mm size is also a great fit for my lens and the multi-coated design helps to reduce any flare or ghosting.

In terms of build quality, the filter is well made and feels sturdy in my hand. It's also easy to install and remove, making it a breeze to switch out as needed. The included carrying case is a nice touch and helps to keep the filter safe and protected when not in use.

Overall, I am extremely satisfied with my purchase of the K&F Concept 62mm ND4-64 (2-6 Stops) ND Lens Filter Variable & CPL Polarizers Filter 2-in-1 and would highly recommend it to other photographers. It's a high-quality and versatile addition to any camera setup.

The Yongnuo 35mm lens is a super prime lens. As a bonus to the 50mm from the same manufacturer, you get a little more on the picture with 35mm. I took the photo of the Federal Administrative Court in Leipzig with this lens for leipzig-days.de and am very impressed with the image quality.

Well, I'm new to photography, my camera is a used Canon EOS 450D and I was recommended at various workshops as a beginner to use a lens with a fixed focal length. So I first ordered the 50mm lens and was so excited that I also ordered the 35mm lens right away. In my opinion, both take really great pictures, so I give a clear recommendation to buy both lenses.

With the purchase of the lens, there was not much standing in my way - because with the kit lens (16-50mm) of the Sony alpha 5000 .. I was anything but satisfied. I got the alpha so that I can take better quality pictures and was very disappointed at first, but didn't want to give it up, after all you've already invested money, so I decided to get a better lens. The images hardly need to be post-processed, at least if you want natural images and not Fotolia-like .. no or really very little chromatic aberration - still quite good at high ISO, focus works perfectly and quickly - even if I prefer manual. And of course the Bokeh theme should not be missing: the backgrounds look naturally beautiful, deep, colorful and soft. So taking photos is now a lot of fun with the alpha 5000! :)

I received this K&F Concept 58mm ND8 Lens Filter (3 f-stops), Fixed ND Filter with Double Sided HD 18 Layers Multilayer, Ultra Thin Optical Mount, Nano-X Series for Lensless Camera Lens in the Amazon wine program. Generate reviews on new products to be heard on Amazon. ND filters are designed to take long exposures and not overexpose photos or change colors. The filter also reduces the intensity of all wavelengths of light without changing the hue of the color rendering. It filters to reduce the amount of light entering the lens. This allows us to choose combinations of aperture, exposure time and sensor sensitivity that would otherwise produce overexposed images. There are difficult ND filters to control the amount of light entering the camera, that's three stops. This K&F Concept ND8 filter is well made and works well. I've only filmed it once so far, but it was very cool. These are a must have for any Phoargophère amateur or professional. I can highly recommend.

I simply copied the complete text from my YouTube video for you. Who wants to see the video
"Variable Nano X Slim ND Filter I pure waste of money when buying?" Enter on YouTube...It's ND Filter that's hard to beat for value for money. It's about a filter from the company K&F Concept, this manufacturer's name is actually familiar to everyone who is - a bit - at home in the photo and film segment. And K&F Concept also stands for quality.
It's about the filter called NANO X Slim Filter. It is offered from a 37mm thread and goes up to a 86mm thread. Thus, it covers almost all offered lenses. He weighs just --- 45gr.
He has a total of 5 f-stops, it starts at ND2, 4, 8, 16 and ND32.
The filter comes with a nice round packaging as a transport box, so that it can also be safely stowed in a backpack or bag. But what is most important, especially for those who always leave the filter on the lens ---like me--- is the fact that glass is the filter's scratch resistant.
Screwing it on and off is wonderfully easy. If you buy it, you should definitely note that you can then usually no longer use your lens hood. Because the thread size on the front lens changes. Attention, however, when buying sun visors - it is essential to pay attention to the zoom range in which the lens is and accordingly buy a sun visor. Of course, I also had to buy a new sun visor, which I bought first was from 24mm, not intended for wide angle. My lens was 17mm – 28mm though. When I was completely in the zoon out, on 17mm, I had nice black edges in the picture. --- Stupid beginner mistake stop. So be sure to pay attention to the zoom area covered by the sun visor before you buy, just as a little tip.
The ND filter can be set very easily to the different ND levels and the individual levels are very well marked, so that you always know exactly which level you are at. Changing the ND levels is so easy because the filter is slightly corrugated all around and has a small pleasant resistance when turning.
In some recessions I've seen that some say the filters would appear to produce X-patterns at high f-stops. What I can't confirm with my film work at first. There is a spin stop, and no overlap, when setting ND16 to ND32, so the X doesn't actually show up. I only have the filter for filming, I'm a videographer, not a photographer, and I think it does a great job. A photographer and a full professional filmmaker will probably not use a variable ND filter anyway. I film a lot at f1.4, f2.0 and 2.8 and shutter 1/50 and even there, although everything is very open glare, the filter comes through perfectly, and very well with. Unfortunately, and that would actually be the only thing you could complain about, is that the filter has no IR cut. In plain language, --- IR, --- means infrared blocking filter. This blocking filter blocks wavelengths in the infrared range. What this filter does not have. But at the price?? somehow also understandable.
What does an ND filter actually do? ...
If some should ask themselves that.
Quickly and roughly explained ---- little basic knowledge.
First and foremost, an ND filter reduces the incidence of light and so you can still film in very bright situations, for example. Without totally overexposing the recordings. So also a longer eg. shutter speed possible. Who doesn't know the great pictures of streams or waterfalls, where the water looks like a veil, like in a dream world. You get that with a good ND filter and exposure time, for example, and not, as some people think or suspect, with good Photoshop skills.
I work a lot on the water, on the beach, on the sea, and that's how I always get the water nice and smooth.
