The item received met my basic expectations. The glass filter (not plastic) is coated on both sides to prevent reflections, which is reflected in the green reflections. The filter frame has been finely and precisely machined with 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, which I also use, I actually notice some differences. In particular, the green-tinted reflections of this K&F filter are more noticeable than the fainter reflections of the Japanese-made Hoya filter (which claims 99.8% transmission). That's to be expected from the much more expensive Hoya, and that's why I use it for a telephoto lens that I use outdoors a lot. However, I don't need the Hoya for every lens I own. I find this K&F filter to be 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 cleaning cloth that came with it came in a factory-sealed package, just like wet glasses wipes (It gives me a little more confidence that the cleaning cloth hasn't been contaminated with tiny sand that could cause scratches. Personally, I don't use this type of cleaning cloth carelessly for filters and lenses, but it's a nice touch.) MAG: - Reasonable price - Precision 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 in 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 are now more expensive than a branded camera*lens* they're used on. That's not a reflection of quality, it's 99% of the marketing. Crazy.)
