49mm MCUV Filter ultra-thin Trapezoid Patterned Frame Coating with a Vacuum Cleaning Cloth Nano-Klear

POSITIVE The K&F Concept K-Series 55MM MCUV Pro UV filter offers excellent protection for the lens. It is made of high quality optical glass and has a multi-layer coating to reduce reflections and maximize light transmission. The workmanship of the filter is solid and high quality. The filter is very compact and lightweight and easily screws onto my lens without adding any extra weight or vignetting. It was also easy to unscrew again. One advantage of the UV filter is its effect in minimizing UV rays. The filter absorbs ultraviolet rays, reducing the blue cast that can often occur when shooting outdoors. This significantly improves the clarity and color reproduction of the photos. In addition, the filter also serves as a protective layer for the lens. It helps keep away dust, scratches and fingerprints, thereby maintaining the longevity and performance of the lens. The image quality with the K&F Concept UV filter is excellent. The filter does not affect the sharpness or contrast of the recordings and delivers clear and sharp images. At least I couldn't notice any negative difference in the test photos. NEGATIVE Nothing. ⭐️ Conclusion: I am satisfied with the UV filter from K&F Concept. It offers excellent protection for my lens and does not negatively affect the image quality, but reduces unwanted reflections and blue tint. I can recommend it and get full marks from me.

Using such a UV filter in front of a lens for mirrorless system cameras or DSLR cameras offers several advantages: 1. Protection of the front lens: A UV filter serves as an additional layer of protection for the front lens of the lens. It can help keep scratches, dirt, dust and fingerprints away from the actual lens. This protects the lens from damage, which is particularly advantageous in environments with adverse conditions such as sand, dust or splash water. 2. Reducing UV light: Although modern lenses already have a built-in UV coating, a UV filter can provide additional protection by blocking ultraviolet light. UV light can cause blurring, hazing and loss of contrast in images. By absorbing UV light, the UV filter can help produce clearer and higher contrast image quality. 3. Easier to clean: A UV filter is easy to clean and replace. If the filter becomes dirty or damaged, the entire lens does not need to be cleaned or replaced. That saves time and money. 4. Reduced risk of lens breakage: In the event of an accident or fall, a UV filter can absorb the impact, reducing the risk of damage to the objective lens. It is easier and cheaper to replace a broken filter than a damaged lens. However, using a UV filter can also have potential disadvantages. An inferior or poorly designed filter can degrade image quality by causing unwanted reflections, ghosting, or vignetting. Therefore, it is advisable to choose high-quality UV filters from reputable manufacturers to maintain the best possible image quality. The K&F Concept Filter from the K series is very inexpensive, but so far I have not noticed any impairment of the image quality. I use it with a diameter of 49mm on the Pentax Limited HD Macro lens with 35mm focal length, which itself has multi-coated lenses, and was curious to see whether the coating of the very inexpensive filter and the HD coating of the Pentax Limited “get along”, but this seems like a good wedding. Protecting the front lens is particularly important to me, because with this macro lens in particular you can sometimes reach the subject itself with the lens, which is not good if it is very hard. Ultimately, using a UV filter in front of a lens depends on personal preferences, requirements and shooting conditions. Some photographers prefer to always use a UV filter to protect their lenses, while others forego it in certain situations in order to achieve the best possible image quality. I myself am more of a mixture of these two types, because if I think it fits better without a filter, I simply unscrew it, which is no problem with the K&F Concept filter, because the thread is milled to fit and precisely, so that it can be screwed on and unscrewed very easily. The Limited's built-in scattered light filter and dust protection cap can also be used without any problems. So far I can recommend the filter without reservation. If I notice anything negative, I will add it to the review.

Whether you need a UV filter or not is up to you, but it does offer some advantages. The most important thing for me is protecting the lens, unfortunately there is already a scratch on my lens. The filter arrives well packaged in a plastic case with cardboard packaging. You also get a soft cleaning cloth. I already have a UV filter, but it doesn't have a thread for the lens hood, so I didn't use it. The filter from K&F Concept has 2 threads, one side for screwing onto the lens, the other side for putting the Geli on, which I personally really like because I always have the Geli on, also to protect against shocks or similar. The thread towards the lens is a bit stiff and I had to fiddle a bit to screw it on. Once you have it on, it sits firmly on the lens. The Geli is much easier to screw on and also sits very firmly. The glass of the filter is clear and without scratches, overall it is very well made. I have the 58 mm filter on my M.Zuiko 40-150 mm R. So far I have not noticed any loss of quality in the images. 4* from me because of the slightly stiff thread, otherwise you can get good protection for your lens for just under €10, which can be easily and cheaply replaced after damage. Repairing a lens is significantly more expensive.

Class UV filter. Rich colors - no fogging or anything else. In addition, there is the protection function class. Only to be recommended.

ordered the K&F Concept K-Series 72MM MCUV Pro UV filter Slim MC for my 72mm lens. The K&F UV filter can be qualified as successful in terms of production. The filter is cleanly made without scratches in the glass etc. The thread is cleanly made and can therefore be screwed onto the lens cleanly. A sturdy box is supplied with the filter for storage and transport. The obligatory microfiber cloth is also included in the scope of delivery. But what does a UV filter actually do? Well, in this case it does exactly what the name suggests, it filters the UV rays out of the light. This used to be extremely important in analogue photography. With today's cameras, at least the higher-priced ones, the electronics can largely filter this out. Such filters are therefore mainly used to protect the lens.

This is the second time I am using a UV filter and the reason I bought it was for my upcoming trip to Bali where I am planning a long photo shoot. Being in the wilderness and in a country with strong sun rays, I figured buying a new UV filter to protect my lens would be best. Well this is a K&F product as is my ND filter and tripod which I recently bought because that's how I am and I like to buy a lot from one company. It came very well packaged and feels like a really good quality and it fits perfectly. I am very happy with the product and look forward to using and abusing it.

The UV protection filter was safely packed in a cardboard box and inside a plastic box. A separate cleaning cloth was included in the scope of delivery. This was also used straight away for assembling the filter. The filter itself makes a really good impression. The workmanship is excellent. I couldn't find any manufacturing or material defects. Everything looks very high quality and the weight is absolutely negligible. When assembling, you should work as dust-free as possible. Before or during installation, it is advisable to use a brush and, if necessary, compressed air in addition to the cleaning cloth to keep the lens really clean before screwing on the UV filter. Screwing it onto the lens is very easy. The thread grips well and everything runs really smoothly until it is finally screwed on hand-tight. The lens is then ready for use. The filter affects the quality of the images in a positive way. It also provides extra protection for the actual lens. The lens cap can also be easily reattached, as can the lens hood. This is exactly how you imagine a high-quality filter to be. I am satisfied and can really recommend the product. Overall, the filter deserves 5 stars. The price-performance ratio is currently 13.99 euros for the 82mm filter (as of 05/2023) and is absolutely okay. There are filters from other manufacturers that cost twice as much with comparable performance. Thank you for reading my review, I hope it was helpful to someone.

The UV filter is a good solution to get more color and more details out of normal photos where the sun is shining a bit. I tested the filter on a Canon EOS 250D with a Tamron AF 18-400 lens. And took the comparison pictures. In the image with the filter, the colors are richer and the clouds are easier to see. The filter also offers good protection for the lens when you're out and about and don't always want to put the cover on it. If you hold the filter up to the light you can also see the coating clearly, which was not the case with my previous filters. The filter can be easily screwed onto the lens and removed again. You can also transport the filter very easily in the packaging provided, but it will throw something around in there because there is no precise hole for the filter.

Economical UV filter I love making motorcycle videos and when I'm shooting on dirty roads I'm forced to use this type of filter to prevent a jumping rock from breaking my lens. Since they all produce UV rays, I leave you with a few photos where I've forced the appearance of the torch so you can see it clearly. Maybe it can be a problem for photos, but it looks cool in videos if you know how to play with it. The white has been yellowed a bit, giving the overall image a slightly warmer look. I hardly noticed any difference in sharpness between the filter on and off. For the price it is, it's great. I used to have one of the Hama brands and I would say this one is better.

was recommended K&F a long time ago and therefore took the opportunity to test this UV filter with a diameter of 77mm on a Nikkor 24-70 f/2.8G. The filter comes in high-quality packaging and with a microfiber cloth, which allowed the item to collect its first points. The filter itself was well protected in a plastic case padded with foam, which can also be used for further transport or storage. The metal ring is structured in two places, which is supposed to make it easier to twist it on and off. Please note that the filter is approximately 3.5 mm thick when screwed on. Even though I didn't notice any impairments with my lens, fringes could possibly occur with wider-angle lenses. In the first photos I couldn't notice any impairments overall. Unfortunately, the weather is currently not so good for taking photos with backlight or cross-incident light. Based on my experiences so far, I can recommend the filter, for around 13 euros for 77mm you can't go wrong.
