The UV filter from "K&F" is shipped in a small cardboard box. There it is safely packed in a sturdy plastic box, in which it can be transported safely and without impact. The scope of delivery includes a cleaning cloth, which is also in a sterile and sealed plastic pack. Despite its low price, the filter makes a very valuable impression. The glass is neatly framed in a metal ring. I couldn't find any distortions or imperfections. The thread is also cleanly cut into the metal frame and can be easily screwed onto my camera. The subsequent application of the lens cap or the sun visor can be done without difficulty. I was looking for a reliable UV filter as permanent protection for the lens on my Sony RX10IV and am very sure that I found it in the UV filter from "K&F". And the cleaning cloth is also very good, contrary to expectations. I used it to clean my smudged glasses, which got absolutely clean without streaks or streaks. So far I have only had such a result with boiled cotton cloths. I can give the HMC UV filter from "K&F" consistently good marks and it is already an integral part of my photo equipment. I would buy it again myself if needed. I give it an absolute buy recommendation.
