NEEWER 49mm ND2-400 (1-9 Stops) Variable ND Filter with Lens Cap, Lanyard, Cleaning Cloth, Precise Neutral Density Adjustment, Fingerprint & Scratch Resistant Multicoated Optical Glass

【49mm Variable ND Filter】 NEEWER ND2-ND400 Variable Filter reduces the amount of light reaching the camera sensor, allowing you to shoot in different conditions with slower shutter speeds and wider apertures. It is perfect for capturing rivers, waterfalls, light trails, and other moving objects with dynamic motion blur 【Accurate ND Adjustment】 Rotate the marked dial to achieve precise ND values from ND2 to ND400 (1 to 9 stops) for optimal exposure. Note: Variable ND filters operate on polarization principles. At maximum aperture, certain lenses and focal lengths may cause an X pattern due to the filter's interaction 【Dual Sided Multiple Coatings】 Optical glass with multiple coatings on both sides ensures neutral contrast and allows you to take images and videos with high color fidelity. The coatings are water repellent, dustproof, anti fingerprint, and scratch resistant, easy for daily cleaning 【About Compatibility】 Only for lenses with a 49mm filter size, please check before purchasing. The ND filter also protects your lens from scratches and features an 52mm wider front frame to prevent dark corners. A ø52mm lens cap, a lens cap lanyard, and a cleaning cloth are included 【Note】 1. Variable ND filters work on polarization principles. At maximum aperture, an X pattern may occur with certain lenses and focal lengths; if this happens, reduce the ND level. 2. For long exposure photography requiring substantial light reduction, consider fixed ND filters like ND64 or ND1000. 3. This filter uses ø52mm lens caps and lens hoods
