K&F Concept 86mm MC UV Protection Filter with 28 Multi-Layer Coatings HD/Hydrophobic/Scratch Resistant Ultra-Slim UV Filter for 86mm Camera Lens (Nano-X Series)

This 95mm filter is top notch. Thanks to its knurled edge, you can get a good grip. It goes on smoothly and just spells quality in every respect. The knurled edge provides a good grip on its matte finish (no specular reflections) The intense multi-coating attenuates UV light and I noticed no distortion or change to image quality.The package included 3 sealed microfiber wipes to keep things clean. That was a nice surprise! So far, this filter has been impressive and a good investment.It’s my 3rd K&F filter and they’ve never disappointed.

I have seldom give a 5-star rating to manufacturers and this one is truly exceptional.I see a ton of thoughts behind everything and a deep desire to solve the customer's problem.It came with 3 microfiber cloth and packaging is superior to Zeiss. The framing ring of the filter is anodized and very high quality with some corrugated edges to provide grip.Inside the holding box, they even thought about sticking 2 pieces of rubber stopper to prevent the filter from sliding when it is being shipped.The glass is crystal clear and has absolutely no dust. It must have been a heck of a clean room for manufacturing.I'll report back when I start using it on my Nikkor lens. If all is well, I'll wave goodbye to Zeiss, Hoya and B+W.

Packaging was premium. It came with a well designed protective case and 3 microfiber cleaning cloths. I wanted a thin protective filter and it certainly was thin and solid. The two ridged sections were effective for insertion and removal. No issues optically but will need more photos to confirm. This my first filter from a Chinese company. I took a chance because this line received solid reviews, and it used Asahi Glass Company (AGC) optical glass. A good value.

I bought this just to be a protective element for the lens. A common concern people have with these filters is the idea that adding more glass onto an expensive lens ruins the picture quality. However, I opened the package and was disappointed to find out they forgot to put the glass in . . . so I thought. The glass element on this filter is so clean and so clear that it's invisible, It looked like an empty circle. Absolutely no impact on image quality but a welcome safety barrier for the front element of my lens!

I pulled the trigger on this filter because it seemed like a nice in between from the $10 filters and the ridiculously expensive filters. I wanted to purchase a UV filter simply for lens protection. A lot of the lenses I use are fairly expensive, and it seems silly to walk around with them unprotected. While I was slightly worried at first that a filter in this price range might degrade some of the image quality with nicer lenses, it's "clear" that it actually enhances it quite a lot. I saw no degradation in sharpness, but colors are a lot better with this filter on, and I can rest easy knowing that my lenses are protected from scratches and debris.They also feel well-built, sleek, and low-profile. They have been usable with the manufactures' lens caps and hoods thus far.I can't give it 5 starts, though, because when stacking other K&F filters on top of this one, they seem to get stuck. I'm not sure if it's the female threads on this filter or the male threads on the filters I'm attempting to stack on top, but it's almost as if they get cross-threaded when you try to separate them (not when you put them on). This makes the filter system slightly less convenient to use overall.

Why expensive brands when there's K&F? Works perfect.

Noticed that my existing 77mm UV filter (not a KEF branded filter) had a mark on the surface just before a trip. Quickly placed an order for the KEF Nano-X series MC coated filter yesterday and it arrived today. Have used KEF filters before and liked their quality and value for the money. The Nano-X series has all the specs I was looking for (Nano coated, mc, quality glass, and ultra slim). The ribbed styled ring aids in easier install and removal. Didn't want to spend more money on similar specs in other filters with no noticeable difference in picture quality. Rated 5-stars.

I put the K&F 95mm MC UV Filter on a 180-200 zoom lens to provide some protection for the glass at the front of the lens. I have noticed no odd coloring or decrease in sharpness when using this filter and I was quite happy with it.I got back from a photo shoot in pouring rain and when hurriedly pulling my camera backpack out of the back of my truck, I accidentally knocked the 180-200 lens (in a dust cover only) out of the backseat of my truck. It fell about 3-1/2 feet to concrete and landed with the lens and filter pointing down. It bent the filter ring in about 1/16 of an inch, knocking the filter lens out of the filter ring but the filter lens was intact. The filter ring was still in place on the lens but the front ring of the lens was also bent, but the lens glass was intact and undamaged. I had to send the lens to the manufacturer to have the filter ring removed and the front lens ring repaired, but the filter really helped to prevent major damage to the lens.I immediately went and bought a second K&F 95mm MC UV Filter and put it on the lens when I got the lens back from the manufacturer. I also bought a padded case for the lens. The attached photo was taken with the 180-200 lens with the K&F filter on the lens. The photo was compressed down from 50MB to 1MB, so any loss of sharpness is due to compression, not the filter.
