I got the filter for my 55mm Sony/Zeiss lens. The front element is recessed a bit... but you never know. The glass is definitely high-quality and well-coated to ensure high transmission and minimal reflections. Even in poor light, I don't see any flares that wouldn't be there without the filter. I can definitely recommend it.

The K&F Concept 62mm Magnetic MCUV Lens Protection Filter is well made and works wonderfully. It’s easy to use and I love the way it looks and protects my lens. It’s a great product for the money.

Convenient to installI had always heard good things about this brand but I had not yet tried the filters. Excellent and very convenient also as an anti-dust. The microfiber cloth cleans very well and the box closes well. In the last photo uploaded you can see the difference with and without the filter. I was under the sun at midday and it helped me a lot for a better result without having to waste too much time. I must say that I am a beginner

Despite this filter’s very low price, I can’t see a difference in the image quality at all. I actually took two test photos and now I can’t tell them apart. (I’m using a 32.5 MP Canon R7 with the Sigma 18-35 f/1.8) This lens filter is very thin and also has filter threads on the front, so that you can still use the normal lens cap. I believe the filter is multi-coated, as when tilted into the light, you can see a green or magenta color. Unfortunately, I don’t have any of K&F Concept’s Magnetic filters, so I don’t know how well that feature works. I only have two complaints: (1) the filter was packaged OK, but there was some wiggle room in the plastic case it came in. (2) The Sigma lens cap doesn’t set fully down on top of the filter, so the lens cap falls off easier. Overall, this is an AMAZING deal for a filter. Again, I see absolutely no reduction in image quality. It is very likely that I will get another of these in the future.

Purchase this filter to protect my 70-200 2.8 lens. In the past I've tried other companies and while I was happy with theirs, I wanted to tryout the magnetic filters. So far I'm quite happy with it's performance. The filter was very easy to install and light transmission is very good. It'll definitely allow you to save time when adding on another filter to your lens. The price is not bad and the built quality seems quite solid. Will

I loved how well this UV filter fit, and the magnetic attachment of other filters was a huge plus. i ordered one for all of my lenses, a couple adapter rings, and a full set of magnetic filters to go with them all

Good product, Good price

The filter arrived well packaged and on time, as usual, at my home. The filter is delivered in a protective box and a cleaning cloth. The filter box is designed for much larger filters (I estimate 82 mm) and doesn't have a suitable cutout for this 67 mm filter. This not only makes the box significantly larger than necessary, but the filter also rattles around during transport. Solution: use your own filter bag, in the right size. If you're familiar with K&F, you don't need to say much about the quality. The materials and workmanship are excellent, and the image quality is also flawless. The different price levels at K&F correspond to better coatings. The K series is obviously inferior to the X series, for example, but also somewhat cheaper. And for most people, the K series will be sufficient, as they are already 18-layer coated, thus also repelling water and dirt well, are easy to clean, and enable outstanding image quality. The filter is quickly screwed onto the appropriate lens. In my case, it's a Canon RF 24-105 f/4. Thanks to its excellent and precise workmanship, the filter also provides perfect dust and scratch protection. Filters generally have a negative impact on image quality; the question is, how much? This filter is very inexpensive at around €20 (67 mm), and I find the quality to be decent. Flares (backlighting that causes unwanted reflections within the lens) seem significantly stronger to me, but that really depends on the lens, and a lens hood is always better than a better filter, unless you can avoid flares or even intentionally use them. A great filter without any loss of quality.

I always use a uv filter over my lens when I’m outside, more for protection than anything. This filter fits well and the magnetic attachment is convenient when I want to remove it quick for a shot and replace it. Seems well made and no real negative effects on photos.

I love K&F products. They never skimp on their lenses and give superb quality. I would recommend this to anyone needing a lens filter
