Feature:1. Neutral density can be adjusted from ND2 to ND400, reduce amount of colorless light reaching film, control each lighting environment.2. Print "Min" (bright) and "Max" (dark) on FaderND outer ring, they are interspersed with a set of punctuation marks, designed to help user accurately reset specific density reference.3. When lens focusing length is in super wide angle range and aperture value is F2.8, if adjust filter to high density for using, relatively obvious "crossing"spot or slight color shift may occur, to insure that image is not disturbed, we suggest you lower filter density value at this point, until disturbing light spot disappears, then shoot normally.4. Using this filter, more freely control aperture and shutter, bringing more exposure means and creation space for photography creation,effectively preventing overexposure.5. ND2 reduces exposure by 1 level, ND4 by 2 level,ND8 by 3 level,number after ND represents ability of ND lens to block light, suitable for dynamic screens, waterfalls, streams, waves, etc.Specification:Condition: 100% Brand NewItem Type: Lens FilterBrand:JunestarMaterial: Aluminum Alloy + Optical GlassColor: As Pictures ShownSuitable Lens Interface Diameter Approx. 55mm/2.2inWeight: Approx.61g/2.2oz.Package List: 1 x Filter 1 x Storage Box
