ordered the K&F Concept K-Series 72MM MCUV Pro UV filter Slim MC for my 72mm lens. The K&F UV filter can be qualified as successful in terms of production. The filter is cleanly made without scratches in the glass etc. The thread is cleanly made and can therefore be screwed onto the lens cleanly. A sturdy box is supplied with the filter for storage and transport. The obligatory microfiber cloth is also included in the scope of delivery. But what does a UV filter actually do? Well, in this case it does exactly what the name suggests, it filters the UV rays out of the light. This used to be extremely important in analogue photography. With today's cameras, at least the higher-priced ones, the electronics can largely filter this out. Such filters are therefore mainly used to protect the lens.

bought this lens filter because I was looking for a filter no thicker than 3mm that would fit in a new Haoge lens hood (which cannot take thick filters) for my X100V to protect the lens and the camera to make weatherproof. If you don't know anything about the new X100V, you need a filter that is weatherproof. After some searching for a 3mm thick filter I found this filter from K&F Concepts on Amazon. I was skeptical that it would only cost £5.99 and there have been some complaints of a color cast. However, I thought I'd give it up for the price. The box it arrived in isn't the best, but it did its job and the filter arrived unmarked. I held it over a white surface and I could actually see a slight shade of brown. However, I don't see any color cast in the pictures. If you hold the filter up to the light you can see a purple reflection. I have tried to show this in the pictures but there is some fading. It looks very similar to the anti-reflective coating you have on glasses - I don't mind that. Overall I'm amazed, it's actually a really good filter with good spread and no obvious ghosting — I shot in the sun yesterday and it worked really well. I've bought far more expensive filters in the past that weren't as good. Recommended — consider buying a second one as a spare!

The UV protection filter was safely packed in a cardboard box and inside a plastic box. A separate cleaning cloth was included in the scope of delivery. This was also used straight away for assembling the filter. The filter itself makes a really good impression. The workmanship is excellent. I couldn't find any manufacturing or material defects. Everything looks very high quality and the weight is absolutely negligible. When assembling, you should work as dust-free as possible. Before or during installation, it is advisable to use a brush and, if necessary, compressed air in addition to the cleaning cloth to keep the lens really clean before screwing on the UV filter. Screwing it onto the lens is very easy. The thread grips well and everything runs really smoothly until it is finally screwed on hand-tight. The lens is then ready for use. The filter affects the quality of the images in a positive way. It also provides extra protection for the actual lens. The lens cap can also be easily reattached, as can the lens hood. This is exactly how you imagine a high-quality filter to be. I am satisfied and can really recommend the product. Overall, the filter deserves 5 stars. The price-performance ratio is currently 13.99 euros for the 82mm filter (as of 05/2023) and is absolutely okay. There are filters from other manufacturers that cost twice as much with comparable performance. Thank you for reading my review, I hope it was helpful to someone.

The UV filter is a good solution to get more color and more details out of normal photos where the sun is shining a bit. I tested the filter on a Canon EOS 250D with a Tamron AF 18-400 lens. And took the comparison pictures. In the image with the filter, the colors are richer and the clouds are easier to see. The filter also offers good protection for the lens when you're out and about and don't always want to put the cover on it. If you hold the filter up to the light you can also see the coating clearly, which was not the case with my previous filters. The filter can be easily screwed onto the lens and removed again. You can also transport the filter very easily in the packaging provided, but it will throw something around in there because there is no precise hole for the filter.

was recommended K&F a long time ago and therefore took the opportunity to test this UV filter with a diameter of 77mm on a Nikkor 24-70 f/2.8G. The filter comes in high-quality packaging and with a microfiber cloth, which allowed the item to collect its first points. The filter itself was well protected in a plastic case padded with foam, which can also be used for further transport or storage. The metal ring is structured in two places, which is supposed to make it easier to twist it on and off. Please note that the filter is approximately 3.5 mm thick when screwed on. Even though I didn't notice any impairments with my lens, fringes could possibly occur with wider-angle lenses. In the first photos I couldn't notice any impairments overall. Unfortunately, the weather is currently not so good for taking photos with backlight or cross-incident light. Based on my experiences so far, I can recommend the filter, for around 13 euros for 77mm you can't go wrong.

The K&F Concept K-Series 55MM MCUV Pro UV filter arrived quickly. It is safely packed in a small box. A cleaning cloth is also included. The filter screws onto my lens easily. Both the sunlight hood and the lens cap also fit on it. The need for a UV filter is debatable. It definitely protects my lens when I'm out and about with the camera in my hand and accidentally bump something. I couldn't find anything negative about the photos either. So I'm more than satisfied.

The UV filter is delivered in a 95x95x17mm plastic box with a cleaning cloth. The filter has an outer diameter of 60.5mm and a 58mm inner thread. The filter fits Canon EF lenses

bought this filter for protection against my very sensitive Sigma lens. The requirements I was looking for were therefore: excellent transparency, anti-reflective treatment, good anchoring thread. I put my choice on this filter, which mainly depends on the price. I have to say I was delighted with it. Excellent transparency, tight and stable thread without any backlash, aluminum frame body, and in addition, anti-reflective treatment is very effective, no vignetting phenomenon or chromatic aberration. Arrived in a practical case, closed in a plastic blister and well packaged. Very happy with the purchase even considering the price. I highly recommend it.

The K&F Concept K-Series 62MM MCUV Pro UV Filter Slim MC UV Protection Filter Ultraviolet Filter (62MM) appears to be a high quality filter designed to protect the lens and reduce UV rays. The filter consists of several layers that are intended to ensure high light transmission and low reflection. The slim design makes it possible to use the filter on wide-angle lenses without causing vignetting. All in all, the K&F Concept K-Series 62MM MCUV Pro UV Filter Slim MC UV Protection Filter Ultraviolet Filter (62MM) seems to be a good choice for anyone looking to protect their lenses and improve image quality.

In addition to the ND filter, this filter from K&F is also impressive across the board. (The polarizing filter is different, not discussed further here). The coating is really good, cleaning does not directly lead to scratches and the results are not distorted. I am satisfied, I have first-class lens protection and can only give it full marks.
