【Neutral Density Filter Kit】 This kit includes four ND filters: ND16/ND32/ND64/ND1000, which respectively reduce the light entering your camera by 4, 5, 6, and 10 stops. They avoid overexposure in long exposure photography and enable you to use wide apertures and slow shutter speeds to capture expressive motion blur effects with a shallow depth of field 【Multicoated Optical Glass】 HD optical glass with multiple coatings ensures sharp images and high color fidelity. Slim aluminum alloy frames prevent vignetting on a wide angle lens 【Simple Everyday Cleaning】 An extendible lens cleaning pen and a cleaning cloth help you easily remove dust, debris, fingerprints, and smudges from filters and lenses without scratching them 【Safe & Organized Storage】 The filter pouch features individual mesh pockets to keep every filter organized and safe. Touch fasteners seal the pouch for protection 【For ø52mm Camera Lenses】 Compatible with any camera lens with a ø52mm filter size. The slim frame avoids vignetting when shooting with a wide angle lens. The filter size is marked on the front or side of your lens, next to a "ø" (diameter) symbol
