K&F Concept77mm MC UV Protection Filter with 28 Multi-Layer Coatings HD/Hydrophobic/Scratch Resistant Ultra-Slim UV Filter for 77mm Camera Lens (Nano-X Series)

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.

I've switched to K&F UV filters from a "competing" brand.A couple of reasons:The filter build quality is superior. These have better "texture" to the metal making them easier to screw and unscrew. The coating looks superior, and I have not noticed any degradation in image quality. Image quality between UV / SKY1A filters is so subjective I won't go into any discussion. Suffice it to say these have no noticeable degradation to picture quality (and I do a lot of macro & wildlife, both ends of the distance / lighting spectrum). Further, I am fanatical about protecting my lenses. The threads on the lens barrel are easily damaged by a drop and the glass can be scratched. I'd rather replace a filter than a lens any time.K&F has a "better filter".Recommended.

I wanted to replace an older UV filter that always seemed to darken my images. I tried this one form K&F as I've owned a tripod and monopod from them and like the quality. UV filters are priced anywhere from a few dollars to >$100, so I tried this one which is about middle of the pack. This filter is really thin and very clear and didn't notice any negative impacts to my pictures. I went ahead and purchased this model in different sizes for all my other lenses. The glass seems strong, and provides an extra layer of scratch protection to my expensive lenses.

First off, a disclaimer: I'm a hobbyist and not a professional/pixel-peeper who absolutely needs the best image quality. Most of my images end up on social media where they can't even be uploaded at full resolution, so having flawless image quality is not completely necessary for me. That being said, I obviously don't want to degrade the quality noticeably, considering I own sharp lenses.My main goal with using UV filters is to protect my lenses from the elements, including fingerprints, dust/dirt, and add some additional weatherproofing (as I mainly shoot outdoors, like on hikes). It's so much easier to clean these flat multicoated UV filters than it is to clean curved lenses, especially those that don't have high-end coatings. Even if these cause minor image quality degradation, I would be willing to live with that to gain the advantages of protecting my lenses and easier cleaning. Fingerprints slide right off of these thanks to the coatings, which you usually can't get with other brands unless you spend a lot more money (e.g. Hoya, B+W).I took a number of test photos with and without the filter to try and find any obvious quality loss. I couldn't spot anything blatant, even on the edges, which is good enough for me. The only obvious issue with these filters is the ghosting when shooting directly into bright light sources, like the sun or lightbulbs. These have very noticeable green ghosting that isn't present without the filter when shooting the exact same light sources (tested on multiple lenses). I usually try to avoid shooting at bright lights, but it may be unavoidable for certain situations, so please consider this before you buy this filter.I haven't used more expensive filters so I don't know if this is simply an unavoidable downside of using ANY filters, but I'm assuming it's pretty common with any filter brand. However, the blue/green tint is a little distracting from these specific filters. It's not worth returning them over, but I'll need to keep this in mind and remove them if I find myself in a situation where ghosting could be an issue. Otherwise, these are great for the money and offer solid protection without causing a big hit to image quality.

K&F filters have been in my camera bag for a long while now and I’m very satisfied with their performance. Highly recommended 🤙

Does its job and as always K&F Concept never fails to bring excellent quality products.

Needed protection for a macro lens and this does the job well, and does not hurt the image quality.

El pedido llego en tiempo y forma, el paquete llego tal cual se ven las imágenes en la pagina, envío seguro y en tiempo y forma. El producto se ve bien estoy satisfecho con la compra, la calidad del producto es muy buena y concuerda con la descripción del producto en la publicidad. Lo acabo de recibir y ya lo instale en un lente de canon RF 24 70 2.8, sin ningún problema quedo pendiente ver la calidad de las fotos. pero espero que me ayude a proteger el lente

This is a basic clear filter to protect the two prime lens that I have. They look well made, fit well and do the job for a great price.

This UV filter was a little more money than I needed to spend but the quality of the filter was worth it.It works so good you can not tell the filter is on the camera. Excellent filter would recommend.

Al principio dude si era original, pero ya que me llego es 100% original, excelente producto
