K&F CONCEPT 77mm MC UV Protection Filter with 28 Multi-Layer Coatings HD/Hydrophobic/Scratch Resistant Ultra-Slim UV Filter for 77mm Camera Lens (Nano-X Series)

The K&F Concept 58mm MC UV Protection Filter is a standout addition to my camera gear. The 28 multi-layer coatings effectively reduce reflections and UV light, ensuring sharp, vibrant images without any noticeable color shifts or vignetting. The filter is constructed from high-quality Japanese AGC optical glass, providing excellent durability and clarity. Its ultra-slim design allows for easy stacking with other filters, and the ribbed aluminum frame ensures a secure grip for installation and removal. Whether you're a professional photographer or an enthusiast, this filter offers reliable protection for your lens without compromising image quality.Fit:Perfect fit.

Unlike some people I believe that a UV filter is a must on a lens for the protection it provides and for the ability to decrease atmospheric haze and glare. But having said that I also believe that the filter must be of high quality with good coatings so that it does not negatively impact your photos. I think that this filter meets these requirements.I have run some simple test taking the same photo with & without the filter and see no negative impact from the filter. The filter is also a good quality filter from a construction perspective and I see it lasting and providing a useful function for a long time, and for a good price.

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.

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.Update: Decided to purchase a second one (77mm) for a new lens I just brought (Nikon 24-120 Z). Great product!

I bought this item based on independent reviews. So far I have not been disappointed. It provides good lens protection at a reasonable price point. The quality is good

I have now purchased several (3) of these polarizers for different sized lens. Good glass, coatings and optics. While these products are not the cheapest, they are not a cheaply made product or a waste of money. Some have complained that the rotating lens is sticky. I've never observed this, among the 3 sizes I have (including the latest 72mm). They are thin, so if your fingers are not nimble you might be challenged.

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.

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.
