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.

I'm just an amateur photographer and can't really judge the exact technical details. I use the UV filter primarily as lens protection. The thread is very well crafted and makes installation child's play. The included microfiber cloth is really good and reliably removes dust. The lens cap still fits without any problems. A clear recommendation from me.

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

Arrived on time. Well done; very thin; light side knots make assembly and disassembly easier, more than acceptable anti-reflective treatment. Excellent value for money (not for professional use). I use it as a front lens protector for the lens. satisfied.

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.

don't want to go into too much detail about the function of a UV filter, or protective filter, as it is often called, that should be pretty clear and I personally have never used a so-called protective filter

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.

The UV filter from “K&F” is shipped in a small cardboard box. There it is safely packed in a sturdy plastic box in which it is transported safely and shockproof. The scope of delivery includes a cleaning cloth, which is also in a sterile and sealed plastic package. Despite its low price, the filter makes a very high-quality impression. The glass is neatly framed in a metal ring. I couldn't find any distortions or impurities. The thread is also cleanly cut into the metal frame and can be screwed onto my camera without any difficulty. The subsequent attachment of the lens cap or the sun visor can be done without any difficulty. I was looking for a reliable UV filter to provide long-term protection for the lens on my Sony RX10IV and I am very sure that I found it in the UV filter from “K&F”. And, contrary to expectations, the cleaning cloth is also very good. I used it to clean my smudged glasses, which were completely free of streaks and streaks. So far I have only had such a result with boiled cotton rags. I can give the HMC UV filter from “K&F” a consistently good rating and it is already an integral part of my photography equipment. I would buy it again myself if necessary. I give this an absolute 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
