Used to protect a Kamlan lens. I don't notice any change in the image with this filter. It was pretty difficult to put the original lens cap back on the lens without removing the lens hood and the UV filter cap is super easy to put back on! And thanks K&F for adding a wrist strap to the hood!

The product is excellently packaged, externally well cared for and inside the filter is housed in a practical carrying case. In the package we find: - Filter - Filter cap - Wrist strap - Vacuum microfiber cloth. I will not go into detail about the technical specifications as they are already mentioned in detail in the product description, but I will tell you about my experience of use and impressions. As soon as you open the package we immediately notice that the product is of excellent workmanship, both in terms of the metal outside the filter and the filter itself, which has an excellent multi-coating that is clearly visible to the naked eye even before trying to take the shot. The cap is also of excellent workmanship, very solid and equipped with the presence of an eyelet to be able to attach a strap to it, which comes together with a vacuum-packed microfiber cloth. I tested the filter with a Samyang autofocus 35mm f2.8 and it behaved really well. During the day I didn't have any special lenses, in night situations you have lenses to do that but only under certain lighting conditions. The loss of detail is very slight and not noticeable on APS-C sensors, slightly noticeable on full frame sensors, especially if we crash in post-processing. In summary, it is an excellent product that is also full of accessories. My final rating is 5 stars

used this UV filter from K&F Concept, Nano-X series, to protect my favorite 50-1.8 fixed lens. Unlike other proven models, this one is really super transparent and really very light, so much so that when you look at it from the front, it almost seems like there is no lens. It is very well made and I really liked that it also comes with a cap of the same diameter and the wrist strap so as not to lose the cap when taking pictures. It also comes with a small vacuum-packed microfiber cloth: I kept it closed and ready, for the first time I have to clean the lenses to always have a clean cloth on hand. The structure that holds the lens is made of thin metal painted black. The filter data is displayed on the side and the screw is perfectly screwed onto the lens head. It is sold in different sizes, so make sure you choose the right size for your lens. Being standard thread, these filters can be used on any camera lens, as long as the lens has the right diameter. When taking pictures, this filter is really perfect: in practice it is unnoticeable and at the same time it protects the lens from dust and scratches. Really good product, which is advertised with bravura for its excellent overall quality and the fact that it is practically invisible in the photos, without creating strange reflections or light effects.

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.

own a few filters (UV, ND & CPL) and other products from K&F. This UV filter came in a square plastic case with a lens cap and lens holder. The filter was clean out of the box. I got this filter for my Nikon 20mm F2.8d lens. So far I have been using the lens without a filter but bought one to protect the front part of the lens when shooting outdoors. Both the K&F and OEM lens caps fit well over the filter. I don't use a filter when I'm shooting indoors. Even outdoors I tend to use one when I'm shooting in dusty environments and only with lenses that don't have a lens hood. It's an extra piece of glass that we put over the lens. It will have some minor imperfections that may be visible when using a pixel peeper. This filter is good, I haven't noticed any degradation in image quality in images I've taken so far. Although I don't use it indoors, I took some pictures to test and didn't notice any difference with or without the filter. The lens cap is OK, but not as good as the OEM cap. The clip is not deep and doesn't provide a good grip. The lens cap holder is a waste. I can't tighten it over the lens barrel so I won't use it. For $10.99, there's nothing to complain about. This is a good filter with a lens cap that protects the lens from dust, scratches, and fingerprints.

usually have a filter on each of my lenses because I like photography in general and motorsport in particular, so the protection offered by a filter never hurts, apart from its benefits in improving contrasts and reflections. As always with K&F, there are 10 pieces, a silver cardboard box entirely screen printed inside a rigid PVC box that perfectly protects the product. Inside this box there is the filter, a protective cap, a fastening strap for the cap and a disposable microfiber suede. As for the filter, two things struck me: how thin the filter frame is and how well built it is to be in the "low" range of the brand. Once installed, the filter is invaluable when viewing the photos thanks to its optical quality, also as a good UV filter it suppresses certain flashes and slightly clears the fog, which is certainly appreciated. As for the construction, the metal frame with two wavy areas, in addition to threading perfectly into the lens, is very comfortable to put on and take off thanks to the knurling. As for a K&F product, I did not expect to be disappointed, but we are not looking at the manufacturer's top offering, but as always, my expectations are improving. The additional case with adjustable strap seems very comfortable to me and it is good to incorporate it, as well as a cleaning cloth for the initial placement of the filter.

This is a polarizing filter from K&F Concept. It comes neatly packaged in a sturdy case with a lens cap, strap and cleaning cloth. I got this 52mm cover for my 50-200mm Canon M50 Mark II and it fits perfectly. It has a nice clear image and I'm very happy with it. If you're looking for a polarizing lens, I highly recommend this one.

The polarizing filter from K&F Concept is delivered in a plastic box together with a cleaning cloth, a lens cap and a strap for attaching the lens cap. Quite a lot of accessories! It's just a shame that the filter slides back and forth in the box without any additional protection. A few cents for a suitable lining would have been worth it. The filter can be easily screwed onto the lens and - so far - removed just as easily. The rotating ring for adjusting the polarizing filter, on the other hand, is very stiff, which I personally don't like so much. Nevertheless, the workmanship does not give a cheap impression at all. According to the manufacturer, the glass has a nano coating, but in my opinion this can only be sparse. When used, this filter changes the colors more than the filter I normally use in a higher price range. All in all, this filter is a very interesting offer, especially for occasional users. At currently just under € 22 for the 67mm version, the K&F Concept polarizing filter is very cheap and offers quite decent quality. I could do without the lens cap and strap, but of course the accessories are not a disadvantage. I give the polarizing filter four stars.
