NiSi Circular Filter "Swift System Black Mist 1/4 (55mm)". This popular filter is used in video and still photography to suppress highlights and create a cinematic texture. 【Features】 Swift System Compatible: NiSi's unique system that allows for easy installation by simply pushing it in. Effect: With a density of 1/4, it provides a moderate diffusion effect, softening and blurring light sources and smoothing skin texture. Size: 55mm 【Reason for Listing/Condition】 I am selling this because the size of my lens has changed. I only tried it on indoors once and have stored it in a dehumidified storage box. There are no noticeable scratches or stains, and it is in very clean condition. Everything in the photos is included. 【Important Notes】 ※This is a filter exclusively for the Swift System. It can also be used as a regular screw-in filter, but it is originally designed to be pushed onto NiSi's Swift-compatible variable ND filters or adapter rings. Please understand the characteristics of the system before purchasing. Please feel free to comment if you have any questions. #NiSi #BlackMist #BlackMist #55mm #LensFilter #Cinematic #VideoShooting #CameraEquipment #SwiftSystem
