【Neutral Density Filter Set】 This kit includes four neutral density filters (ND2/ND4/ND8/ND16), a lens cleaning pen, a cleaning cloth, and a filter pouch. For long exposure photography and a shallow depth of field, these filters can slow down the shutter speed, create dramatic motion blur, and avoid overexposure when using a wide aperture 【Premium Construction】 The optical glass ensures sharp images and high color fidelity. The CNC aluminum alloy frames with black anodized treatment are lightweight and durable 【Clean Filters & Lenses Easily】 A retractable lens cleaning pen with two tips helps you easily remove dust, debris, fingerprints, and smudges from filters and lenses without scratches 【Safe & Organized Storage】 The filter pouch features individual mesh pockets for every filter to keep filters safe and portable. Touch fasteners seal the filter pouch for ultimate protection 【For 58mm Camera Lenses】 Compatible with any camera lens with a 58mm 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
