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 is transported safely and shockproof. The scope of delivery includes a cleaning cloth, which is also in a sterile and sealed plastic package. Despite its low price, the filter makes a very high-quality impression. The glass is neatly framed in a metal ring. I couldn't find any distortions or impurities. The thread is also cleanly cut into the metal frame and can be screwed onto my camera without any difficulty. The subsequent attachment of the lens cap or the sun visor can be done without any difficulty. I was looking for a reliable UV filter to provide long-term protection for the lens on my Sony RX10IV and I am very sure that I found it in the UV filter from “K&F”. And, contrary to expectations, the cleaning cloth is also very good. I used it to clean my smudged glasses, which were completely free of streaks and streaks. So far I have only had such a result with boiled cotton rags. I can give the HMC UV filter from “K&F” a consistently good rating and it is already an integral part of my photography equipment. I would buy it again myself if necessary. I give this an absolute purchase recommendation.
