I had previously looked at the individual reviews of various protective filters and then decided on this one. I'm ruined and would buy it again at any time.

The K&F Concept K Series 82mm MCUV Pro UV Filter is a must for every photographer. The slim design and high quality construction provide excellent protection for my lenses while minimizing unwanted glare or UV light. The filter's multi-coating ensures excellent image quality with reduced reflections and improved color saturation. With the K&F Concept UV filter, my photos are sharper, clearer and more vibrant. It's a reliable and essential tool that I highly recommend to other photographers.

I also liked the packaging with cleaning cloth.

Shipping/Packaging/Scope of delivery Shipping is typically fast for Amazon. The filter is housed in a well-padded plastic container with foam and there is another box around it. The scope of delivery also includes a microfiber cloth, which is practical for cleaning the front lens before installation and can also be used beyond that. Quality/feel/look/design The filter makes a very, very high quality impression. I also ordered a pole filter from the same supplier, and it feels just as great in terms of feel and quality. The filter ring/filter thread is also milled metal and slides precisely through the filter thread of the lens without rubbing. Really very successful. Function Well, I'm not describing the function of a UV filter here, anyone who wants to order one probably knows what they are used for. I always use UV filters as a basic filter on all my lenses, in this case on an already coated Olympus 12-100 Pro, to protect the front lens. Since the UV filter has another filter thread at the front, you can easily combine it with other filters, for example effect filters, polarizing filters, etc. Price/performance: Excellent, I would buy it again at any time for this price! Great feel, functions perfectly! Doesn't exist.

UV filters are often advertised as being able to improve image quality. In my opinion this cannot be determined. This does not make the image more contrasty, sharper or whatever else. On the contrary, even if the filter has high light transmission and is multi-coated, annoying reflections that are visible in the image can still occur through the filter. So if you want the absolute best image quality, you should avoid (UV) filters completely. Nevertheless, I find UV filters practical because they can at least protect one lens from dust, dirt and damage. Even when cleaning a lens, in the worst case scenario you can scratch the glass if, for example, there are fine grains of sand on the surface. Personally, I like to use protective filters, but opinions differ on the subject. The K series from K&F Concept is practically the entry-level series. With 18 layers of Nano MC coating, the filters are already decent, definitely better than uncoated or simply coated filters, but higher-priced filters would also be better coated and therefore even less susceptible to annoying reflections and even more translucent. Basically it's a difference of a few percent. I think the filter is inexpensive considering the quality. I use the 77mm filter with a Canon RF 14-35mm F4 L IS USM.

review the K&F Concept K-Series 67MM MCUV Pro UV Filter Slim MC UV Protection Filter Ultraviolet Filter, which was kindly provided to me free of charge by Amazon Vine for testing. My opinion is unaffected by this fact, my review reflects my experience with the product. I will get this filter again for money Why? Because it fits my fleet and I have finally found affordable, high-quality protection for my favorite glasses. I have to place the thread very flatly so that it doesn't get caught (no hectic moves; it can be unscrewed calmly but in a relaxed manner). I work with fast lenses and don't see any serious changes when stopping down. There is still one advantage - the sky is a bit bluer in the picture

A must for the expensive Canon lens, as it primarily protects the lens from scratches. Easy to screw on and hold firmly. Since I always use a UV filter, I can't describe the difference.

Especially in times of digital photography, you no longer really need a UV filter. However, I personally like to have one installed for protection; even if the "scholars" argue violently and defend themselves because every additional lens robs quality. I am very satisfied with the filter delivered here. The threads fit well and grip well at the same time, so that nothing simply comes loose again. I was skeptical because of the very narrow design of the lens cap. But this still fits perfectly and is held securely. And there are no problems when using a lens hood either. I didn't notice any deterioration in the images either. By the way, the filter was packaged very well and was well protected. Full five stars and, especially given the low price, a clear purchase recommendation.

K&F Concept K-Series 55MM MCUV Pro UV filter Slim MC UV protection filter Ultraviolet filter As expected, the filter from K&F Concept is of good quality and design. It can be screwed in and out easily and cleanly. It is also possible to use a second filter. With 3 filters there are unfortunately edge shadows/vignettes in the wide angle 18 - 20mm on my Sigma 18-50mm f2.8 DC DN C. Otherwise there are no negative influences on the image due to the filter. As a protective filter at the price “TOP TOP TOP!” Price - performance - quality

was provided with a K&F Concept K-Series 62MM MCUV Pro UV filter free of charge. It is delivered in a stylish silver-colored box with a K&F Concept print. In addition to the plastic box with the filter, you will also find a microfiber cleaning cloth. There is a QR code on its packaging that takes you to the K&F homepage. The filter is again in a plastic bag. I don't think that's a bad thing, as it prevents contamination before use. Before use, the glass is free of any fine surface scratches - I've had this happen differently with much more expensive filters. So far I have nothing to complain about in terms of functionality. I've always used filters as protection on my old Panasonic FZ1000 because you can't just swap the lens. (I've also had to replace the filter I used from time to time, problems happen quickly in the heat of the moment.) The filter can be easily screwed onto the lens and doesn't get in the way. It is often said that such UV filters affect the photos taken. I have never noticed this before and it is likely - if at all - only in an area that is perhaps just measurable but not visible. For only €11 I think you can't go wrong with the K&F filters. It's possible that some more expensive filters might be more scratch-resistant, €11 hurts far less when damaged than an expensive filter or even the camera lens. (However, I didn't intentionally test the scratch resistance - if anything turns out in one direction or the other, I will update the review if necessary.) For the moment, the filters get a full 5 stars from me.
