KANI's magnetic black premium mist filter. I bought it, but it's completely unused. I'm selling it to organize my belongings. Instant purchase is OK. KANI Magnetic Black Premium Mist (BPM) No.4 HT100 IV-M95 / Black Mist Effect A magnetic "Black Premium Mist" filter compatible with the HT100IV magnetic adapter ring. It can be quickly attached and detached without screwing when combined with the magnetic adapter ring. Exquisite diffusion effect reminiscent of a movie scene. Soft depiction overall while maintaining a core. Low-reflection coating allows use for both stills and videos. Available in 5 types: No. 1/2/3/4/5, depending on the strength. *The higher the number, the stronger the effect. This is an improved version of the product previously sold under the name "Cinema Diffusion Filter (CDF)". *It suppresses aging, which is also known for CPL filters, and provides high durability of the mist effect. KANI BPM has a low-reflection coating, which minimizes flare and ghosting even when emphasizing strong point light sources, and is also coated with anti-static, water-repellent, and oil-repellent properties. KANI is committed to not compromising on performance and cost, even for special effect filters. The package features a photo by Mr. Koji Ueda.
