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.

Very nice filter to use. Every photographer can use it to expand their spectrum. If you are always looking for new impressions, you will find exactly what you are looking for here. Even on sunny days there is a lot going on with this! The image quality leaves nothing to be desired, the packaging is sensible and attractive, including a box for storage. The glass is well made, no scratches and high-quality framed.

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.

I have to admit that I didn't buy the filter primarily as a UV filter, but rather as a protection for the lens. I was a bit skeptical because some other buyers wrote that the filter was scratched or dirty. I cannot confirm this. It was packaged well and securely, and thanks to the padding and plastic box, you can store it safely away when not in use. In terms of image technology, I didn't notice any real difference when taking pictures - but it has to be said that I'm not a professional. I didn't notice any vignetting either.

Delivered in a plastic box that protects it well, the filter looks very nice and the polarization works well. I will also use it mounted on the lens to protect it. Useful and high quality

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.

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.

A dirty filter arrived, it wasn't just dust and after 10 minutes of cleaning with a special liquid and a lot of attention, it went away. I contacted the manufacturer and after a few days he replied and sent me a new filter to replace, recommended!

K&F makes decent gear for the money I found and this UV lens filter is no different. In all honesty, this is extremely well made, offering a quality finish and the feel of a seriously expensive kit. I appreciate that the jury is out on whether or not a UV filter is needed and I have no real feelings on the subject. However, what I like is that using a UV filter prevents damage to my actual lens within reason. Okay, I understand that if I drop my camera off the back of a truck it won't survive, but this lens filter will prevent minor scratches and swarf. It also keeps my fingers away from the lens and because it's flat it's easy to clean thoroughly with a cloth. Overall a no-brainer for me. I always put a UV filter on my lenses immediately after purchase just to give a bit of protection and K&F has some great filters for absolutely reasonable money.
