This filter perfectly fits the Sony SEL-35F18 standard lens (fixed focal length, 35mm, F1.8). After buying the lens, I screwed on this filter to protect the lens from dust, scratches and other external influences. Recommendation.

I bought a Canon EOS M100. I bought this UV filter to protect the lens. As with other reviewers, I can confirm that I don't see any distortion or similar impairments. Installation: The filter simply twists onto the lens (clockwise). Canon lens protectors can still be used. As before, you only put the UV filter in this. The UV filter arrived well packaged for me. I could use it straight away and didn't have to clean it beforehand.

The UV filter has a high-quality and clean finish. I really like the blue-purple reflection and it really makes a difference. I didn't notice any changes in image quality, but there could be a slightly different, increased lens flare. If you like the look, you will be satisfied with the filter. In any case, I can recommend it as protection for the lens!

Great filter, feels very high quality, images are still sharp, unfortunately massively dirty from the original packaging, fingerprints everywhere, but can be used again after 10 minutes of cleaning.

For my Panasonic Lumix G lenses, I needed two "protective filters" so that rain and fingerprints can't damage the front lenses. There are different opinions on the net about the effect of UV filters, so I don't want to say anything more about it, but there is a blue-tinted coating on the K&F Concept Pro UV filter, the delivery condition is perfect and the packaging is (especially in view of the the price) can almost be described as luxurious. A first check also reveals no adverse effects on the image quality in any way, and the slim design also means there are no shadows on the 12mm lens. Lens caps still fit securely and the lens hood also fits on the lens in both directions. I see the handy " there are even tools that make this removal possible. But that's a thing of the past here, with this practical ribbing on the edge it's no longer a problem. At this price you can also have one or two of these filters with you in your camera bag and when the mud has splashed you can quickly put a clean one on it - easy Perfect! there are even tools that make this removal possible. But that's a thing of the past here, with this practical ribbing on the edge it's no longer a problem.

What else should I write about the positive reviews that already exist? All the information given about the product, i.e. filters, is consistent and can easily keep up with more expensive products. Absolutely satisfactory for me and my lenses. Again any time.

For me a very good polarizing filter, use it on the Sigma 10-20mm 3.5 Ex for Nikon!! So far no reflections or loss of sharpness! Of course you lose 1-2 light levels because the filter glass is darker. But that's normal. Example photos: 1. 20mm with filter, 2. without filter, 3. 10mm with filter, you have to be careful because the full power of the lens is coming!! With a 10mm filter, always turn it back a bit, because the angle to the sun always causes barrel-shaped blue coloring! But not because of the filter! Is wide angle (physically) due, even with very expensive polarizing filters! Great value for money, of course!!, Use the filter in landscape photography!! Otherwise without!!

UV filters in the digital age only make sense to a limited extent. I mainly use this type of filter as protective glass for the lens, so that I don't have to worry about damaging the lens even on the beach or during somewhat hectic photo shoots. The protective function is very good with this filter well achieved.The workmanship is good, the glass is clear and without inclusions.The edge of the filter is thin enough so that there is no vignetting.The blue coating is a bit annoying.If the sun hits the filter unfavorably from the side, it will creates a blue shimmer in the photos. Of course, that shouldn't be the case. However, this phenomenon only occurs at very specific angles to the sun. But the price-performance ratio is good, so ⭐️⭐️⭐️⭐️

Very nice filter to use. Every photographer can use it to expand their spectrum. Anyone looking for new impressions will find exactly what they are looking for here. Even on sunny days there is a lot going on! The image quality leaves nothing to be desired, the packaging is sensible and attractive, including a box for storage. The glass is well made, no scratches and high-quality framed.

I only bought the filter to protect my lens. The filter is quite thick for my standards, but can be screwed onto the lens to some extent. I've had smoother ones before. But okay so far.
