tested it out in my house and on the grounds of my building today and had some excellent results with it. It blocked out glare in puddles and on windows, improved contrast shots across a rain-soaked driveway, and produced an intense blue sky from a fairly washed out light blue sky with thin clouds. The filter construction is very high quality, the threading feels positively solid and is neither too stiff nor so loose that you'd fear it'll come off. The rotation of the polarized display is a little stiffer than I'd like. A couple of times I found that when I was past the ideal level and wanted to back off a little, the filter unscrewed. I don't like tightening filters too much, so I'm hoping it will loosen up a bit with use. It comes in a sturdy, if slightly bulky, plastic box that I replace with a more compact filter case when I'm out and about. Also included is a lens cap and lanyard. I don't remotely like the lens cap, the front edges of the push buttons on each side are sharply bevelled and they have no grip so if like me you have quite dry skin it's not easy to hold onto, in fact I dropped it twice within minutes of opening the pack so I found it quite funny when I saw the little video in the advert which was expected to just extol the virtues of the filter only to find out it was actually just about the cap and that the lanyard is there to stop you losing it. In over forty years of using SLRs and DSLRs I have never come across a lens cap that was less suitable for an active photographer on location. Lens cap aside this is a great filter, it does everything you'd expect from a product that's priced far higher than the £13.99 it currently costs and should last a couple of years if looked after. Perfect for beginners or experienced photographers and incredibly good value for money. What's not to like.

At 49mm, the filter is perfectly adapted to the Fujifilm X100 V/VI (assuming you have a suitable one, of course). It seemed to me to be of very good quality and comes with a strap and a protective cap, which will come in handy since the original lens cap of these cameras does not fit a filter. We will not use a polarizing filter under any circumstances, but for the sky, macro or portrait shots, it can give interesting results. porte-filtre adapté At 49mm, the filter is perfectly adapted to the Fujifilm X100 V/VI (assuming you have a suitable one, of course).

K&F Concept circular polarizing filter, Nano-K model, in the 67mm version. I tested it on a Tamron 28-75 F2.8 and compared different shots to see the loss of light and sharpness with and without the filter. It comes in a pack that also includes a front cap, a wrist strap and a microfiber cleaning cloth. The filter has a very good build quality and has reliefs on the front that allow easy rotation. The polarizer effect is clearly visible, similar to more expensive products. In all the conditions in which I tested it, it loses 1 stop of light. The sharpness remains similar to the lens without the filter, you notice less detail when you zoom more than 200%, otherwise they look like two identical photos (the one with the polarizer is darker if you don't change the shooting parameters). The thread flows very well, as with all filters it tends to fit too tightly to the lens and then becomes difficult to remove if you're not careful. Very low price, good value for money.

This is beautifully presented, both from the outside and inside of the box. It comes with a lens cloth, hard case, lens cap and a lanyard to attach it to the lens so you don't lose it. You can see the filter on the lens next to a glass filter in the photos. The dark one is this filter, the clear one a plain glass. You can see the filter removing glare in the car photos. Pros: 1. A well made and well presented filter. 2. A good selection of extras, a case, lens cap, cloth and lanyard. 3. I've tried it on camera and it adds detail to clouds etc. Cons: 1. The lanyard cannot be attached with the lens hood on. (The lanyard is a bonus though) There's not much not to like. The quality is good and the extras a bonus. I think it's good value for money.

Overall, this is a great filter for the price. It's easy to install and you can twist it to change the effect on the lens. The edge of the lens is rubbery so you can hold it in place while you twist it. It does a great job of reducing glare from pictures taken near water or in strong sunlight. Overall, a great addition to the kit. It comes with a lens cap, travel pouch, cleaning cloth, and a lanyard so you can attach the lens cap to the camera if you want.

I know this is cheap but it feels cheap... the filter works fine and you get the results you want when taking photos with glass or reflective water in the frame. The adjustment/rotation of the filter feels rough, not as smooth as its metal counterparts. Also it feels rough, it doesn't screw on as easily as I would like... It works and does its job, great for a first filter but not good for a budding pro.

This circular polarizing filter worked unexpectedly well to remove unwanted reflections and glare. Images were clear and colors appeared much richer. When using the polarizing filter, images are a little darker, so always shoot RAW for professional results and easy editing. By rotating the filter, the effect of the polarizing filter was visible in the viewfinder, which made composing my shots very easy. The build quality seems good and it feels pretty sturdy and well made, but it's not a 5-star CPL filter. Rotating the filter wasn't smooth or easy. Overall, it's not perfect, but it's good value for money and is a great CPL filter for long exposures.

The K&F Concept 55MM Polarizing Filter is a quality addition to my photography gear. The ultra-thin design and multi-coated Japan optics provide excellent clarity and reduce glare effectively. It comes with a lens cap, which is a nice bonus. The Nano K series lives up to its reputation and improves the colors and contrast of my photos. This polarizing filter is a great investment for any photographer looking to improve their shots.

Really nice lens filter. Appears to be of really good quality. No issues with it. Screws on well to my third party Fuji lens!

I own a dozen or so filters from various manufacturers for my cameras. We all know that when you're looking for a filter, you will see offerings that run the gamut on pricing, and sometimes it's hard to tell the difference between an inexpensive product and one that costs more. The moment I received this filter, I knew it was special. Let's start with the packaging. Instead of being shipped in just a dinky box or plastic bag, this has a sturdy cardboard box with a metallic sheen. The outside is also completely printed with QR codes for info, specifications, etc. On the inside, you get a sturdy, transparent storage case that snaps close. Inside is the filter with a LENS CAP attached, as well as an orange lanyard. As a bonus, you will get a sealed cleaning cloth. I don't think I've ever purchased a filter that came with a cap retention lanyard and a lens cap before. I am using this for my Fuji X100V, and of course, it fits perfectly. I can use the included lens cap with any filter I decide to use. The only con I've found is that once you get this on and rotate clockwise a few times to get the right CPL effect, the threads are really tight. The threads are also so short that it's hard to get a grip on just that area to get them off. I had difficulty removing the filter from my camera and had to resort to a filter wrench. However, this is not unique to just this filter. All filters could have this problem with removal.
