don't like putting anything in front of the lens, but what I like least of all is the possibility of damaging a lens that cost me so much that I couldn't afford to buy it again since I didn't make a living from photography. I've tried a few "unbranded" UVs, but the quality of the filters matches the price and either the image lost some sharpness or the colors and sometimes both were affected. I'm testing this MC UV from K&F Concept with a Canon EF 24-105 f/4L lens and although I've only taken a few quick and poorly made test photos for now, I haven't noticed any of the above like loss of sharpness or color. I've added some photos taken without changing any parameters, with and without the filter, and I hardly notice any difference between them. Other than the fact that the cover can be attached while the filter is screwed to the lens, it stays there for now.

K&F Concept is probably a well-known name among many amateur photographers as a provider of high-quality yet affordable photo accessories. I have already been able to test a few of the brand's filters and was therefore all the more excited about the brand's UV filter. I actually only use UV filters to protect the glass of the lens. In order to reduce the deterioration of the lens' image quality as little as possible, it is very important that the glass of the UV filter is of the highest quality. This UV filter is absolutely color-neutral and nano-coated, so that water droplets run down the glass without leaving any residue. Even when looking closely, I cannot see any influence on the image quality. The UV filter therefore does exactly what I want it to do - protect the expensive lens without deteriorating the image quality. The current price of €27.99 is, in my opinion, completely justified in terms of quality and workmanship and is rather affordable. So I give it five stars.

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!

It comes in a sturdy plastic case that's ideal for storing the filter and protecting it from scratches in case you need to store it in a camera bag with other items. The filter itself has a solid construction with clean and clear glass so there are no marks to be seen. The 72mm thread fits perfectly on my Sony A-mount kit lens, and I also found the included lens cap particularly helpful (my lens didn't have one previously). After testing my camera with and without the filter, I noticed the difference immediately — the filter significantly reduced the amount of "haze" I could see when pointing the camera at a particularly brightly lit area (that was natural light coming through a window). Also included in the kit is a cleaning cloth and a lanyard that keeps the cap attached to the lens, which come in handy should you need them. In summary, a good value item.

This UV filter offers great value for money compared to filters from premium brands. It protects my lens just as well while barely affecting the light. The screw connection is smooth. The cap is made of lighter plastic than premium brands but works perfectly.

This concept product from K&F is very well built, has a very thin frame and is therefore suitable for sharp wide angles. The knurling allows for easy assembly and disassembly. The anti-reflective coating is very effective and even when the sun is shining in the car, it does not produce any reflections other than those of the lens. It does not even introduce dominants and the light fall-off is absolutely negligible. Great

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

already have several products from K&F, and I must say I'm starting to appreciate their range of quality accessories. This filter was purchased solely to protect the front element of my expensive Sony 16-35mm lens. I particularly like the attention to detail, especially on the bezel ring, with its precisely machined grooves for better grip, and the included lens cap and microfiber cloth, which will always come in handy. There's also a lanyard there for those who want to use it. I prefer not to have anything dangling from my camera while in use. I'm happy to report no vignetting at 16mm focal length, and the images/shots are sharp and crisp. The use of AGC glass tells me everything about the quality of this UV filter, and that's exactly what you're paying for here. A cheap filter on Amazon costs an average of $10 without a lens cap. And a good lens cap costs around $10 as well. So this kit offers excellent value for money and I can only recommend it!

I am becoming increasingly impressed with K&F filters. I have a selection of them and find them to be well made and do not degrade the image. This is another one I have added to my kit. There are different schools of thought when it comes to filter use and I am of the must use type. These types of filters protect your expensive glass. Over the decades of holding a camera, a UV/Skylight filter has saved the front element of my lens from impact. The filter takes the hit and shatters but the lens remains intact. Very happy with this new filter.

This is K&F Concept 24-layer coating, ultra low reflectivity 0.4% and anti-glare UV filter, better specs than the budget ones. Actually, I can't tell the difference with their cheaper similar models for my grandchild's photos. Of course the difference is there, so I use it for my most expensive f1.2/1.4 prime lenses. Maybe a thousand dollar lens should have a more expensive UV filter for some people.
