62mm Magnetic CPL Filter Circular Polarizer Lens Filter Optical Glass Ultra Slim with 18 Multi-Layer Coatings Nano-Klear Series

This is an innovative design that removes the need for you to swap your protective filter (UV or whatever) on the occasional need for a polarizer. I've tried keeping the outer ring where this fits on top of my normal UV filter. It just snaps on. Of course you should take it off and not meant to be kept there permanently since a reasonably hard bump will unstick it. However, if you're doing landscapes on a tripod, and not walking around this is good. Optically, its very good. I've no complaints. I am a bit surprised that it seems the sky was bluer without the filter than with. I'll have to do more tests to see. Probably modern digital cameras compensate the colors. It was a Nikon Z7ii.

Pretty happy with this filter. The magnetic aspect makes it a breeze to pop on and off. No cross-threaded filters or fumbling. The CLP works well and does what it is supposed to do. Diminishes glare and intensifies blue skies. A CPL is one of those filters I never go without, especially for landscape photography. The filter is well-made and finely machined.

Polarized filters are super handy for when there is glare off of a surface like glass or water. Usually, this means taking out thr right filter, screwing it on and then taking your picture. With this filter, it has built in magnets so it just pops on! This makes it super easy to go from off to and back to off in a snap. Adding this to your collection of filters is way worth it!

good product

After years of using screw-in filters and square filter holders for neutral density filters, magnetic filters are a breath of fresh air. They are quick and easy to fit to the front of the lens and easy to adjust. The optical quality of this CPL is very high -- no colour cast or other optical issues -- and I was able to do fine adjustments when shooting at a lake to carefully control the amount of reflection (see picture). I also like the price: very competitive compared to some other magnetic filters that cost as much as a new lens!

regularly go out into nature with my dog and carry my Nikon D750 with various lenses, the most important of which all have a 77 mm thread. Especially in the forest and in the Harz Mountains, I always use a polarizing filter to reduce reflections from leaves and water. The only problem is that polarizing filters always absorb light, and you have to extend the exposure time accordingly, which is disadvantageous if I want to spontaneously photograph my dog. Until now, I was skeptical of magnetic filters because I wasn't sure whether they would hold up well when hiking through nature with the camera and the filter attached. Accordingly, I welcomed the opportunity to test this filter from K&F as part of the Vine program. I've already had very positive experiences with K&F products. While your program covers a very broad spectrum, you have some very high-quality products that are aimed at ambitious amateur photographers, particularly because of their lower prices. This filter is also one of their better products, which you notice right away when unpacking it. The filter is very cleanly crafted, with a precise magnetic thread and filter fit. The filter comes in a matching box, and a lens cloth is also included, well-protected in aluminum packaging. Overall, everything makes a very good impression. The thread screws onto the lens easily, and the magnet pulls the filter into place and holds it very firmly, allowing the filter to be rotated easily without slipping. Because of the slim design, it barely affects the image, even with the 16 mm wide-angle lens. This filter has completely put to rest my fear that a magnetic filter might fall off while hiking. It sits really securely and firmly on the lens. Yet, it can be removed very quickly when needed, which is much more convenient than the time-consuming unscrewing process. For me, this is a significant improvement in the handling of filters in outdoor photography, where you often have to adjust your equipment on the fly. I think I'll rely more on magnetic filters from now on; the test convinced me of their functionality. The filter performance is clearly in the better range of the polarizing filters I use. There are really big differences in the reduction of reflections and color fidelity, and you have to invest quite a bit if you want reliably good filter performance. I'm very satisfied with the performance of this filter; you can clearly see how reflections are reduced when you turn it. Overall, this is another highly recommended product from K&F.

This is a RATING REVIEW for the item for sale on Amazon with description: K&F Concept Nano-K Magnetic Filter, CPL Circular Polarizing Filter made of Optical Glass with Nano Coating for 77mm Lens (Includes a Cleaning Cloth). This is a CPL filter (polarized light control by turning on its axis) very comfortable to use thanks to its two-piece system: threaded anchor ring and filter with magnetic outer ring, the threaded ring is installed and then it can be removed with a simple grip and pull of its contour (which has a ridged texture for a better grip) and to fix it again, present it to the ring and position it until you notice the magnetic pull and its anchor in a well-aligned position. As for the benefits, they are noticeable outdoors with good sunlight (indoors and artificial light it is not noticeable and in very shaded outdoors either, so it is usually used in landscape shots, especially those where an area of sky or clouds appears or where there is a reflection of light in rivers, springs, lakes, etc ... or with metallic effect reflections. Depending on the orientation in which the ring is turned, the image becomes darker or lighter a little, attenuating the sunlight and taking more or less color saturation (when turning it on the magnetic system it has a little sound like a squeak of friction, but as it is normally used in photography and video, the position is first searched for and then the recording is activated, it does not affect the audio of the recordings. I have made an edited video with some image changes on the same shots only by partially turning the CPL polarizing ring. The images appear with a greater color tone but less luminous, for this reason it is advisable to retouch the gain of the exposure meter a little, since when turning the ring if we are in manual mode with reference to this or in the preference modes aperture or speed control varies the shooting speeds or diaphragm openings respectively, and I personally like the images a little more vivid, both colors and luminosity, but without annoying reflections. Due to its very good price / quality ratio and its ease of installation and exchange with filters of the same system "Magnetic adapter ring" magnetic fixing ring, its thinness of support "Slim" that prevents vignetting in angular lenses, its good presentation in a protective box and the special cleaning cloth included in the set my rating for this K & F concept filter is: " 5 STARS " = [ * * * * * ] . I hope you find this review useful, Greetings. The drawback that I forgot to mention and noticed later is that on CANON lenses with the front caps of the EF range, these are not held either with the filter installed or with the filter ring with the filter removed, as the filter is narrow format (SLIM) the support tabs of the front lens cap do not engage the profile of either the filter or its support ring, so in order to put the cap on you have to also remove the threaded ring and store the set in its box.

Got the 77mm for my 24-70 and 70-200 Canon zooms; it came nicely packaged with a sturdy filter case and microfiber cloth. Screwed in easily on both lenses and works great!

This polarizing filter comes in its protective box and a cleaning cloth. The magnetic design separates the filter into 2 parts: the magnetic ring that screws onto the lens permanently and the filter that sticks magnetically to the ring. The strength of the magnet is sufficient to secure the filter and prevent it from falling during use. However, you should not hit it too hard! The rotation of the filter is smooth and pleasant. I recommend always turning the filter in the screwing direction to avoid the risk of unscrewing the ring over time. The ring is very thin and does not interfere with the installation of the lens hood. However, be careful not to snag the filter when removing the hood; it is only held by magnetism, remember. Once you understand the principle and the particularity of this flexible and practical system, it is comfortable! And of course, if you are juggling with other filters of the same type, it is super quick to change. The optical quality is also there. I recommend it.

Capturing the essence of a moment, that's what photography is all about. And when it comes to elevating your shots, the K&F Concept 82mm Magnetic Circular Polarizer Lens Filter is a true game-changer! From the moment I secured it onto my lens, a whole new world of possibilities unfolded. This sleek and ultra-slim filter is a marvel of engineering, boasting 18 multi-layer coatings that effortlessly cut through glare and reflections. Whether I'm shooting landscapes or portraits, the polarized effect adds a depth and richness to my images that leaves me awestruck. But that's not all the magnetic design is a stroke of genius, allowing for seamless attachment and removal without any fuss. Say goodbye to the frustrations of traditional filters and embrace the future of photography with this ingenious creation from K&F Concept. Pros outweigh the cons, but the slightly higher price tag is a small price to pay for such outstanding quality.
