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.

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

First pic is (with golfer) no filter; second (no golfer) is with filter. That's the goal - protect the lens and do not degrade photo quality. Here: mission accomplished. These pics taken two minutes apart; same settings on my camera.

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.

I was running through an intersection with my A7iii in hand, I tripped and fell right on the front of my lens element, and rolled onto my wrist and elbow.

The UV filter cracked and got a huge dent on the metal rim, and it saved my $500 lens! No damage done to my lens, only the filter and step up ring.

I’m replacing it with another, definitely worth the low cost.

I purchased this concerned about keeping my camera lens protected and smudge free. The purple and blue hue is absolutely gorgeous! (see picture) This UV filter makes photos slightly warmer, which is expected since it's blocking out the higher frequency wave-lengths. I wasn't expecting the frame to be made of metal either, it feels really nice to the touch.

I bought this UV protection filter for my Sony 28-70 kit lens, it good fit and great protection filter. I can not tell the difference between filter and no filter in the most shots. It is also pretty light. I am really satisfied with this good made and high quality UV filter.

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.

Added this to my Olympus 40-150 f4 for my Italy trip. My pro photograoher buddy talks about not using filters or anything on his lenses. Quote glad I didn't listen to him this time. It didn't have any negative effects on my pics, and it saved my lens when the very uneven sidewalks of Rome had me misstep and take a dive landing on my camera and lens. One edge took the brunt, cracked the filter. Lens and camera are pristine.

Can't get the filter off and will wait until I get home. Still have a day of shooting so I just broke out the filter glass and kept on going. Will take needle nose pliers and twist the metal filter ring off. Hopefully the lens threads are useless now. We shall see.

First time I've ever damaged a thing on my equipment, but you never have an accident until you do. Considering the lens was just purchased, I'm glad it saved me from making that lens even more expensive if it would've been salvageable at all sans the filter.
