40.5mm MCUV Filter Ultra-Thin Trapezoid Patterned Frame Coating with a Vacuum Cleaning Cloth Nano-Klear Series
SKU: KF01.K40V2
The title of this review pretty much says it all about the K&F Concept 52mm MCUV Lens Protection Filter; in fact even the product's name calls out its most important function. This type of filter is mainly used to protect our expensive camera lenses and K&F is upfront in naming their product as a "Lens Protection Filter."
As such this product seems to be made well and, in use, has not introduced any aberrations, glare or ghosts to pictures taken with the filter either directly on the lens or in addition to other filters. It is very thin and has both inner and outer 52mm threading. In comparison, the K&F UV filter is much thinner than the same type of filters sold by other manufacturers without any discernible difference in photo results. My only complaint is that attaching the K&F filter, like many other K&F filters that I've tried, can be a bit tricky and produces a more distinct "scratchy" sound than other filters as it is being screwed onto its mount. However, I've not been able to see any negative results that could be attributed to that 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 possible purchase list if you are shopping for a UV protection filter. Its competitive price and thin form factor, together with a lack of any evident drawbacks, are definite plusses and I therefore rate this lens a solid 5 star product.

K&F really has a great product line for filters like this one. I am using this on a lens more as a protective element but I've noted no discoloration, no reduction in picture quality and all at a steal of a price. The filter is well made, screws in easily and did not bind at all.

My thoughts on K&F Concept 72mm MCUV Lens filter.
This is a decent UV lens filter for the price. It has a multicoated surface and a smooth thread that fits well with my lens and other filters. Its thickness it comparable to my UV filter of another brand.
In terms of quality, it seems that it does not affect the colors or sharpness of my photos.
I compared some shots with and without the filter and they look almost identical. Maybe the filter makes the whites a little brighter, but it is hardly noticeable.
I think it will do its job of protecting my lens without compromising the image quality. I think it would be hard to beat the price.
Yes, I am glad with this order!
Thanks!

quality filter, slim, clear, and lightweight.
Greenish coating, tested with 13mm on an APS-C camera, with no dark corner and no color shift.
Would definitely recommend it if you are looking for budget multi-coated UV filters.

This filter well made with metal ring that is easy to hold and turn. At first glance, it is not a slim or low profile ring that is thicker than my other slim filters. The concern is about possible vignetting when wide angle lens is used.
The product description claimed it can go as wide as 14mm without vignetting. While I don't have extra wide angle lens that wide, I did test it on a 12mm Fourth Third lens that is equivalent to 24mm full frame wide angle lens and I did not see any sign of vignetting and the ring is easier to hold and turn than some of the ultra slim filters.
Overall, this filter is a good value and low cost way to protect your lens.

The clearest UV I have ever used. When I first opened it I thought it was broken and there was no glass. Turns out it was just insanely clear.
Even my friend was so impressed they ordered some for their lenses

I recently bought a new 40mm lens and I always use UV filters for general lens protection, especially since lenses are so expensive nowadays. I decided to pick up this K&F Concept 49mm UV filter which will basically always live on my lens unless I decide to use a different filter for an effect. I really like this filter, especially the grooved sides which make it easier to grip to screw or unscrew on or off. I have not noticed any detrimental effects to having this extra piece of glass on the front of my lens, which is great! Seems really nice quality. Oh, and I forgot to mention, they even included a microfiber cleaning cloth in the box!

I got a new camera mainly for video work and I needed a nice "budget" priced UV filter. This filter works very well and so far and I am very pleased with the results. The filter is made with excellent quality AGC glass with multiple layers of nano-coatings to prevent reflections and glare. Also, I really like the way they put the ribs around the outside diameter to assist screwing the filter onto the lens. The frame is very light and thin, which works very well with my wide angle lens. So far I have used this filter with my camera several times for some test videos and photos and have been very pleased with the picture quality. For the price, this is an excellent filter choice for any beginner to intermediate videographer or photographer. It also comes with a nice lens cleaning cloth. I highly recommend this filter.

I use the K&F Concept UV filter in size 52mm on my Fujifilm XC 15-45mm kit lens on the Fujifilm X-T30 II, primarily as protection for the front element – and I'm absolutely satisfied.
The filter is very well made, the glass is clear, multi-coated, and doesn't affect image quality at all. Colors, sharpness, and contrast are fully preserved – even in backlit situations, I couldn't detect any distracting reflections.
It fits perfectly on the lens, is easy to screw on and off, and thanks to the slim aluminum frame, there's no vignetting, even at 15mm. For a compact lens like the XC 15-45, it's truly ideal.
Cleaning is also very easy – fingerprints and dust can be wiped off effortlessly, which is incredibly convenient when you're out and about.
In conclusion:
A high-quality UV filter that fits my Fujifilm setup perfectly. It reliably protects the lens without affecting image quality. Absolutely top-notch for the price – a clear recommendation for anyone who wants to protect their lens in the long term.
