As soon as you open the package you immediately understand that we are dealing with a quality product because it comes with a very nice rigid packaging and the UV filter is sealed separately inside, all for 8€, what can I do say more? I've been trying it on Lumix 25mm f/1.7 for a week and it's perfect: it doesn't change color and saturation at all, for me it's 5 super deserved stars.

Hardly any reflections or other image effects compared to other filters. And for the price

The offered filter has an excellent coating and good light transmission. It's well packed, dust free and the cleaning microfiber cloth is a nice touch. However, it's not for every lens out there. While I like the knurled ring for better tactile feel, it makes it impossible to fit the lens hood on certain lenses like my Sigma 45mm 2.8 lens. The knurling protrudes beyond the diameter of the filter and interferes with the hood. I hope that K&F will offer options when it comes to the design of their filter rings to circumvent this problem.

I have the UV protection filter on almost all of my 7 lenses. Not to reduce UV radiation, but to protect my lens glass. The UV filters arrive well packed in a plastic box. I can recommend the filters without reservation.

I have used a few K&F filters on my camera lenses and have never been disappointed with their quality or price. The UV filter is made of high-quality optical glass and leaves no color cast or other imperfections on my images. Put simply, what you shoot is what you get, just beautiful, clean images. This type of filter also serves a secondary purpose as a protective filter for your expensive lens. After all, it's cheaper to replace a filter than a lens, isn't it? Overall, I am very happy with my K&F Concept 46MM UV Filter Ultra Slim Japan Optics Multi-Coated UV Protection Lens Filter and have no hesitation in recommending it.

Filter is very cleanly processed, thread runs smoothly, nice, non-slip ribbing for easy screwing and unscrewing. Glass clean and free of grease. No change in image quality (color, etc.). Was mainly intended as a lens protection. Has yet to prove itself in strong sunlight.

I bought the gals to protect the lens of my FZ83. I can't say anything negative about the quality. My lens cap fits and the frame is made of nice high-quality metal. The Gals itself has no negative influence on my pictures.

First impression - fits, well packaged and the lens cap from Sigma also holds on. Would I buy again. Image quality has not yet been tested, if necessary I will write something later.

The processing quality is good. Both filter threads are good. I had no trouble mounting it to my lens and screwing the lens hood. The plating looks good and is pink in color just as advertised. Good buy. Recommended.
