Non-smoker, no pets. Stored in a room with temperature controlled by air conditioning. This is a KANI HT PRO+ MC UV-IR-CUT 105mm diameter lens filter. I only attached it to a Sony FE 400-800mm F6.3-8 G OSS lens and took one test shot after purchase. As shown in the second image, the filter produces very clear images. There are no scratches, and I have not touched or wiped the lens part. I will lightly tape the corners to prevent the contents from moving during shipping and will ship from the Yamato Transport office in Kanagawa.
