Shipping/Packaging/Scope of delivery Shipping is typically fast for Amazon. The filter is housed in a well-padded plastic container with foam and there is another box around it. The scope of delivery also includes a microfiber cloth, which is practical for cleaning the front lens before installation and can also be used beyond that. Quality/feel/look/design The filter makes a very, very high quality impression. I also ordered a pole filter from the same supplier, and it feels just as great in terms of feel and quality. The filter ring/filter thread is also milled metal and slides precisely through the filter thread of the lens without rubbing. Really very successful. Function Well, I'm not describing the function of a UV filter here, anyone who wants to order one probably knows what they are used for. I always use UV filters as a basic filter on all my lenses, in this case on an already coated Olympus 12-100 Pro, to protect the front lens. Since the UV filter has another filter thread at the front, you can easily combine it with other filters, for example effect filters, polarizing filters, etc. Price/performance: Excellent, I would buy it again at any time for this price! Great feel, functions perfectly! Doesn't exist.
