K&F CONCEPT Variable ND Filter ND2–ND400 77mm (B Series) + Microfiber Cleaning Cloth

Includes: K&F CONCEPT adjustable neutral density photography filter ND2~400 plus a professional microfiber lens cleaning cloth. Materials: Variable ND Filter is made from Completed Professional Optical Glasses instead of optical resin. The included microfiber cloth is produced from Japanese Raw Material — very soft and ideal for cleaning lenses, filters, eyeglasses and mobile devices. Design: Features a Super Slim Original Design to minimize vignetting during shooting. Important Notes: 1. Confirm your lens thread size before purchasing. The thread size is usually marked on the lens barrel or printed under the lens cap and is preceded by the diameter symbol (Ø). For example: Ø 37 = 37 mm lens thread, Ø 62 = 62 mm lens thread. 2. When the filter is set to its maximum density (ND400) or higher degrees, an "X" spot or blur may appear in images; this is normal. Suggested remedy: reduce the density setting gradually and stop down the aperture until the facula disappears. 3. The calibration marks on the filter ring are intended for reference only and are not precise indicators of specific density values.
