The title of this review pretty much says it all about the K&F Concept 52mm MCUV lens protection filter; even the name of the product indicates its most important function. This type of filter is primarily used to protect our expensive camera lenses, and K&F directly names its product as a “lens protection filter.” Therefore, this product appears to be well made and, when used, did not cause any aberrations, glare or ghosting in images taken with the filter, whether directly on the lens or in combination with other filters. It is very thin and has both an internal and external thread of 52mm. In comparison, the K&F UV filter is much thinner than the same type of filter sold by other manufacturers, with no noticeable difference in photo results. My only complaint is that, like many other K&F filters I've tried, attaching the K&F filter can be a bit tricky and produces a more noticeable "scratching" sound than other filters when screwed onto the mount . However, I did not find any negative results that could be attributed to this sound or its creation. All in all, I think the K&F Concept 52mm MCUV Lens Protection Filter is a product that should definitely be on your potential purchase list if you are looking for a UV protection filter. The competitive price and thin form factor, as well as the lack of obvious drawbacks, are clear pluses, which is why I rate this lens a solid 5-star product.

I recently purchased a K&F Concept 72mm filter for my 50 1.4 zeiss lens and have been extremely happy with its performance. The filter was easy to screw onto the front of my lens and fit perfectly, with no vignetting or other issues.

One of the main benefits of using a UV filter is that it helps to protect the front element of my lens from accidental damage. This is especially important for my fancy lens, which is a high-quality and expensive piece of equipment. The filter is also useful for blocking out UV light, which can be especially helpful when shooting in bright sunlight or at high altitudes.

In terms of image quality, I have noticed a slight improvement in the overall clarity and color accuracy of my photos since using the UV filter in the Colorado mountains. Blues and purples in particular seem to be rendered more vividly and accurately.

Overall, I am extremely satisfied with my purchase of the filter. It provides excellent protection for my lens and also helps to improve image quality. I would highly recommend this filter to any photographer looking to protect their lens and improve their photos.

The Nano X series has been a staple in my lens collection for some time, but I've never tried the more economy-focused K series. I'm pleasantly surprised by the multi-layer quality of the K-Series for only $11. (67 mm at the time or when writing). It's certainly not as good as the X series, but for cheap protection on a kit lens that's totally fine.

We have an optometrist in the family. That means that we are all very conscientious about our eye health. She has two children and they both had sunglasses as babies. She did this because UV rays can be damaging and can actually end up causing problems like cataracts and macular degeneration down the road. The same reason our family member has a vocal concern about our eye health is the same reason that photographers should use a UV filter. A UV filter is a glass filter that block ultraviolet (UV) rays and protects camera lenses from dust and scratches. With that in mind, I was excited to add the MC UV Protection Filter from K&F Concept to my filter collection.

The first time I took this filter out, I was out to dinner with my family. We decided to try out a new restaurant in town that has a rooftop dining room. We arrived and got seated around 6:00 p.m. and the sun was hitting the rooftop full force. I pulled my camera out and screwed the filter into place. It wasn’t difficult to secure on the lens, which was refreshing since some filters don’t like to line up properly sometimes. But this filter twisted on smoothly and without any catches.

I’m actually going to back up a moment to say that before I took it out into the blinding sunshine, I did a quick test at home. I simply held the filter with one hand in my photo booth. I looked at my other hand in the light and then moved the filter over top of the exposed hand to see what the difference was. It was interesting to see how much of a difference the filter was making -- even under an LED light. The bluish tint was eliminated and my hand looked warm and like I was viewing it in HD.

Now, fast forward to our rooftop dinner and how I noticed the clarity of the images was greatly improved by this very simple filter. I walked around the roof and grabbed a few shots that would normally appears dull in that type of direct sunlight. With the UV filter, they appeared vibrant and clear rather than hazy. I also really like how slim the filter is because it doesn’t add a lot of weight to the existing lens when I’m using it.

The K&F Concept UV filter was an unexpected surprise for me. It is really well made and does a great job with filtering sunlight. I love that I have an added layer of protection on my lens when I got out and about and that my outdoor images look better than ever.

This product came early and well secured not to mention they even added microfiber cloths for the smudges if any goes in your owns but it’s a really good buy of quality I recommend 5Star buy

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

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.

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.

Economical UV filter I love making motorcycle videos and when I'm shooting on dirty roads I'm forced to use this type of filter to prevent a jumping rock from breaking my lens. Since they all produce UV rays, I leave you with a few photos where I've forced the appearance of the torch so you can see it clearly. Maybe it can be a problem for photos, but it looks cool in videos if you know how to play with it. The white has been yellowed a bit, giving the overall image a slightly warmer look. I hardly noticed any difference in sharpness between the filter on and off. For the price it is, it's great. I used to have one of the Hama brands and I would say this one is better.
