About this product: 【ND Filter】This is a 67mm variable ND filter. Please check your lens size beforehand. Variable ND filters have a double structure, so the filter frame is generally one size larger, but measure the size with calipers or similar before purchasing a cap. Please note that a lens cap is not included with this filter. 【No X-Shaped Artifacts】The X-shaped artifact prevention variable ND filter is equipped with a light quantity lock function. After adjusting the level by rotating from a minimum of ND2 to a maximum of ND32, the automatic lock function fixes the position of the glass, avoiding the angle at which the filter causes unevenness, and preventing the appearance of X-shaped artifacts. 【ND2-ND32 Variable】This light reduction filter reduces the amount of light without affecting the color. Adjustable in 5 steps (stops) from ND2 to ND32. While allowing for the diverse expressions of the lens, it enables the use of slow shutter speeds even in strong light environments, allowing you to smooth the flow of clouds and waterfalls, and express light trails. 【Water-Repellent and Anti-Smudge】The filter surface is processed with 28 layers of nano-coating, achieving water and oil repellency. You can shoot with confidence even in harsh environments such as rivers, mountains, and deserts. High-quality reinforced optical glass is used, significantly reducing lens flare and ghosting, suppressing reflections, and allowing you to freely take bright and colorful photos. 【Thin Frame & High Transmittance】Despite being variable, it uses an ultra-thin 7MM glass, and is a thin-frame specification that can also be used with wide-angle lenses. It achieves high transmittance and low reflection, maximizing the descriptive power of the lens.
