The scope of delivery and material are good. As usual, screwing it onto my lens was very easy. The filter doesn't turn as easily as my previous one, but it has a bit more grip on the outside. I really like the lens cap, which isn't pressed to the side like my original, but in the middle of the cap itself, which is a clear advantage with lens hoods, which I also use. I can't say anything about the quality of the polarizing filter yet, I'll take a few sample photos as soon as the weather finally improves.

CPL filter (polarization filter) is a must for ambitious photographers. The company K&F Concept supplies a filter that comes with a lens cap, lanyard and microfiber cloth, a set that meets even the highest demands. I screwed the filter onto my OM system camera with a 58 mm zoom lens. It is not too easy to turn, so it does not move by itself in the camera bag. Since it is also quite inexpensive, the set gets five stars.

bought the polarizing filter for the camera kit of my Xiaomi 14 Ultra. The polarizing filter fits perfectly on the camera kit's adapter. The lens cap is nice to have. I have no experience with these filters, so I can't judge how good or bad this one is compared to others, but picture 4 shows a shot without a filter, picture 3 shows a shot with a filter, and there is a clear difference! More will only become apparent when testing "in the field", but the first impression is very good.

When unpacking, the filter makes a good impression, the workmanship is clean. Screwing it onto a lens is easy, there are no problems. Once attached, the filter can be rotated with little resistance, and it fits. But unfortunately the effect of rotating the filter is very slight, it can be done much better. For comparison, I have uploaded photos that were taken once with the K&F Concept filter and once with one from Amazon Basic. The difference in effect is significant. You can get even more out of a more expensive branded filter. Considering the price, I'm giving it 3 stars. The polarizing filter is OK for beginners to try out, but if you want to take ambitious photos, you should spend more money. Disclaimer: The product was provided to me free of charge for testing as part of the Vine program, but this expressly has no influence on my objective review.

As you would expect from K&F, this is a top quality polarizing filter. It is very easy to install using the thread. However, you should screw it on gently, otherwise it will be very difficult to remove. The reflections are filtered out well and the quality of the image is not affected.

The K&F Concept Polarizing Filter 55mm CPL filter impresses as usual with its high-quality workmanship from K&F. I could not detect any disturbing influences on my pictures with this filter either. The effect of the filter is rather subtle, but it is good for reducing reflections. Overall, I can recommend the filter without reservation. So if you are looking for a simple CPL at a great price, you can't go wrong with K&F.

Comes with cloth, cap and wrist strap. The 52mm adapted perfectly to my lens. The filter is circular and allows you to vary the reflections to blur them or on the contrary to accentuate them. Darken the shot a bit to compensate with the camera settings.

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.
