The item received met my basic expectations. The glass filter (not plastic) is coated on both sides for anti-reflection, which is reflected in the green reflections. The filter frame was finely and precisely machined using CNC machines; it was easy to screw onto a lens. When I examine this K&F filter side by side with a much more expensive Hoya Fusion UV filter that I also use, I actually notice some differences. In particular, the green-tinted reflections of this K&F filter are more noticeable than the weaker reflections of the Japanese-made Hoya filter (which claims 99.8% transmittance). That's to be expected from the much more expensive Hoya, and it's also why I use it for a telephoto lens that I often use outdoors. However, I don't need the Hoya for every lens I own. I find this K&F filter pretty good enough for my less frequently used lenses and for most situations. (And if the situation is particularly prone to ghosting, for example, I know enough to simply remove the filter in that particular situation.) (I also liked that the included cleaning cloth came in factory-sealed packaging, just like wet eyeglass wipes . This gives me a little more confidence that the cleaning cloth hasn't been contaminated with tiny sand that could cause scratches. I personally don't use this type of cleaning cloth carelessly on filters and lenses, but it's a nice touch.) LIKES: - Reasonable price - Precise CNC machined filter frame - Anti-reflective coatings on filter surfaces, good enough for most normal situations. I like the balance between good enough quality and reasonable price that I find with this K&F Concept UV filter. It is mainly used to protect the lens from sand and dust. That's why I give this filter 5 stars. (Some filters on Amazon are now more expensive than a brand camera *lens* they are used on. That's not a reflection of quality, but 99% of marketing. Crazy.)
