55mm Variable ND3-ND1000 (1.5-10 Stops) Filter Nano-Xcel Series - 28 Multi-Layer Coatings for Camera Lens

My equipment: Canon 90D 18-135mm 3.5/5.6 USM lens I really love this cover. I have never had an ND filter before, but I am completely blown away by the features of this one. As you can see from the photos I've uploaded, they work wonders in filtering out some of the harsh light from day shooting, they also let me capture a pretty awesome sunrise! I have not used them for motion photos, yet, as I typically do landscape photography, but they do help with pictures during the day to avoid having overly exposed areas in your pictures. The case it comes with is also top tier, made with nice leather and easy to remove from the package when you're looking to use it. I have not noticed any white balance issues with it, but I take all my photos in RAW format, so I don't usually pay much attention to my white balance (I fix that in the editing process). The lens itself is great quality, as well. It adjusts very easily and tethers nicely to my lens. I cannot speak highly enough about this filter, if you are shopping for something to bump your photography to the next level, this is an excellent place to start!

Ah, the variable ND filter from K&F Concept—strong in the ways of the Force, it is. Crafted with the precision of a lightsaber duel, its Japanese AGC optical glass, multi-coated with 28 layers, shields against the dark side of glare and reflections. Clarity, it bestows. The putter adjustable design, clever it is. Like a Jedi adjusting his focus in battle, one may fine-tune the stops with ease, rotating the frame with the grace of a master wielding his blade. From ND3 to ND1000, versatility this filter grants, useful across many landscapes and scenarios. Waterproof and scratch-resistant, it is. Strong against the elements, it stands. Oil-proof and hydrophobic, like a Jedi’s robes repelling the chaos of the galaxy, this filter remains resilient through the trials of adventure. Vignetting, it does not—unless the wrong lens thou useth! A slight dark "X" may appear, but turn the frame, and balance in the Force is restored. Turns water into smooth, wispy trails even in bright light, this filter does. Like the flowing energy of the Force, movement transforms into an ethereal dream. But heed this warning, young Padawan—manual mode, you must use. Settings to Master the Force of the Filter: Shutter Speed: Slow, you must make it. 1/4s to 30s, depending on water’s movement and light. The longer the exposure, the smoother the trails. Aperture: f/8 to f/16 is wise, for clarity and depth, it ensures. But adjust, you may, depending on conditions. ISO: Keep it low—100 or 200, lest noise disturb the balance of your image. Focus: Manual focus, use. For sharpness, a Jedi does not rely on the camera alone. Also works great at night, it does! For streaking lights as they pass by, perfect it is. Speeder bikes on Endor, landspeeders on Tatooine, or city streets in Coruscant—long exposures, you must use. Night Photography Settings for Light Streaks: Shutter Speed: 10s to 30s, for motion trails that flow like the Force. Aperture: f/8 to f/11, for balance between light intake and sharpness. ISO: 100-400, depending on ambient light. Too high, and noise will corrupt the image. Tripod: Essential, it is. A Jedi’s hands, steady they may be, but long exposure requires stillness beyond mortal ability. Compatible with all 77mm lenses, this filter is, but beware—an 82mm lens cap, thou wilt require. Such knowledge, crucial it is, lest disappointment consume thee. Verdict: In the ways of photography, a Jedi must always choose his tools wisely. Strong with the Force, this filter is. Recommended, it comes highly.

Out of the gate the first thing you’ll notice is the build quality on this filter. It it feels really solid in your hand, there are no loose parts and has a good weight to it. I like how it has little grip extenders that you can grab a hold of to turn the filter. As the filter does need a little bit of pressure to turn it, it’s nice to have these so your fingers don’t slip. I like how it has hard stops on the ND filter so you don’t accidentally turn it too far, which can mess up your image really quick regardless of what brand filter you’re using.

ND filters are essential if you're going to be shooting with anything that may involve bright outdoors. For example, you can use an ND filters indoors to lower the exposure of an outdoor window, and then you can add lights to bring the exposure back up of your subject, that way both are perfectly exposed. K&F Concept made the interesting design choice to add a putter, and I'm all for it. It makes the function of changing the ND value a lot easier to do than the traditional way, mostly because sometimes I've tried to rotate a part of the filter but it wasn't the part that actually controlled the ND value. Overall, I really recommend this filter. It's fantastic!

The package containing the K&F Concept Nano X-Series Variable ND Filter ND3-ND1000 Neutral Density Filter 67mm (1.5-10 f-stops) was delivered quickly and securely packaged. I love photography and was delighted to be able to test this filter. The black outer box containing the filter was covered with a plastic film to prevent any moisture from penetrating. The filter itself comes in a high-quality plastic case. The flap of the case is magnetic, so there's no unnecessary fiddling around to get to the filter. Very practical: The filter can be easily lifted out using a strap. The whole thing looks really classy and would also make a great gift for an amateur photographer. The filter itself is made of Japanese optical glass with a 28-layer nano-coating on both sides, which is supposed to prevent a certain amount of lens reflection and, of course, glare from various light sources. According to the manufacturer, the ND filter is waterproof, oil-proof, and dustproof, which is particularly useful in nature and when hiking. I have the feeling that the filter is very robust. It weighs 45 g with a 67 mm lens. Of course, the price is correspondingly reasonable. The filter frame is made of aircraft-grade aluminum, has an ultra-wide-angle design, and is just 7.4 mm thick. Anyone like me who has always used several different darker neutral density filters will appreciate the fact that they only need one filter. I use neutral density filters primarily for photographs of water by a lake, flowing water, or waterfalls. They are also fantastic for long-exposure shots of places where you would like to photograph without people. The function of this adjustable filter is quite simple. Operate the practical slider, and the filter darkens or brightens as needed (see photos). This makes it easy to try out different settings and effects without having to constantly change filters. However, I must also mention that you can't attach the lens hood to this filter because the slider gets in the way. It's a bit impractical, but hey, you can't have everything... Conclusion: The price is within the normal range for this type of aperture adjustability. Sure, there are cheaper options, but the K&F filter is built with a somewhat higher quality. The results are certainly impressive. Since I'm not a professional but simply enjoy photography, this filter is actually a great companion for me and I can recommend it with a clear conscience. As a product tester, I study each product I test very intensively, putting it through its paces, so to speak, and only give reviews that I can fully stand behind. I hope my review was helpful to you.

Packaging and shipping

ordered this K&F Nano X-Series Variable ND Filter ND3-ND1000 (52mm) for my "always-on" lens. The filter arrived at home very elegantly packaged, including a leather case. I tested the filter on my 28/2.8; it screwed on without any problems, and adjusting the aperture worked perfectly thanks to the very pleasant resistance and the integrated nosepiece. The filter produces neither color casts nor image aberrations. The ND3-ND1000 is a perfect companion for me from wide-aperture photography in daylight/sunshine to long exposures, so it's very versatile. I can definitely recommend this filter due to its excellent quality (workmanship/image quality). Best regards, Holgi

K&F Concept filters are always very high quality. I've never owned a neutral density filter before, so I'm excited to be able to test this one. The packaging itself is very high quality, and the included leather case is very nice and sturdy. The filter can be easily pulled out using the strap. The case flap is magnetic. The small orange handle makes it very easy to adjust the filter. The effect is amazing. It helps you easily adjust the exposure in a wide variety of lighting situations. I mainly use it in lighting situations where I want to photograph with an open aperture and the daylight is too strong. The colors in the image are not negatively affected by the filter. Great filter at a reasonable price. I give it 5 stars.

already have a variable ND filter, but I'm not satisfied with it because the dial is stiff and the results don't meet my expectations. Having already given up on ND filters, I came across a product review for this K+F filter, which impressed me so much that I ordered this filter for my new lens (Tamron 35-150mm f/2.8f). The packaging (high-quality cardboard with a magnetic holder), the gold-decorated insert, and the leather storage case gradually convinced me that this is a high-quality product. The filter arrived dust-free, has visible coatings, and a really easy-to-use dial for dynamically adjusting the filter. The screw thread is flawless, and the initial results are significantly better than my attempts with the more basic filter. I'm satisfied, but I expect this level of performance even at such a high price. I highly recommend it!

I was very reluctant to buy an ND filter for a while until I took the plunge with this one, and it's been a turning point in my image and video capture. The quality is superior and it makes my work much easier.
