Dispatch/packaging/scope of delivery Dispatch typically fast for . The filter is housed in a well-padded plastic can with foam, and there's another box around it. The scope of delivery also includes a microfiber cloth, which is practical for cleaning the front lens again before installation, and can also be used beyond that. Quality/haptics/optics/design The filter makes a very, very high-quality impression. I also ordered a Pol filter from the same supplier, and this is just as great in terms of feel and quality. The filter ring/filter thread is also milled metal and slides precisely and without rubbing through the filter thread of the lens. Really very successful. Function Well, I'm not going to describe 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 base 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 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! Top feel, function flawless! Doesn't exist.
