The UV protection filter was safely packed in a cardboard box and inside a plastic box. A separate cleaning cloth was included in the scope of delivery. This was also used straight away for assembling the filter. The filter itself makes a really good impression. The workmanship is excellent. I couldn't find any manufacturing or material defects. Everything looks very high quality and the weight is absolutely negligible. When assembling, you should work as dust-free as possible. Before or during installation, it is advisable to use a brush and, if necessary, compressed air in addition to the cleaning cloth to keep the lens really clean before screwing on the UV filter. Screwing it onto the lens is very easy. The thread grips well and everything runs really smoothly until it is finally screwed on hand-tight. The lens is then ready for use. The filter affects the quality of the images in a positive way. It also provides extra protection for the actual lens. The lens cap can also be easily reattached, as can the lens hood. This is exactly how you imagine a high-quality filter to be. I am satisfied and can really recommend the product. Overall, the filter deserves 5 stars. The price-performance ratio is currently 13.99 euros for the 82mm filter (as of 05/2023) and is absolutely okay. There are filters from other manufacturers that cost twice as much with comparable performance. Thank you for reading my review, I hope it was helpful to someone.
