This 55mm ND2-400 & Black Mist 1/4" 2-in-1 lens filter combines a light-adjusting ND filter with a softening black mist filter. The optical glass is precision-ground and polished on both sides to ensure molecular stability, ensuring high-resolution images without affecting the sharpness of telephoto lenses. While the exteriors may be a mix of new and old, the internals are identical. [ND Filter/Light Intensity Adjustment] The variable ND filter features a light intensity lock function. It can be adjusted in 9 steps (stops) from a minimum of ND2 to a maximum of ND400. By rotating the front frame of the filter, you can eliminate reflections on water surfaces and shop windows, improving color contrast. You can also adjust the light intensity with the lever, reducing the amount of light without affecting color. [Soft Effect - Black Mist] Reduces highlights and brings out dark areas. Captures soft, diffused light in backlit situations, reduces contrast, and adjusts brightness and darkness to create a soft, cinematic atmosphere. By reducing highlights on skin, it creates a smoother look while maintaining the definition of the subject. [Water-repellent, dirt-resistant multi-layer coating] The lens filter is made of optical glass with 28 layers of nano-coating on both sides. The glass surface is coated with excellent water-repellent, oil-repellent, and scratch-resistant coating, making it easy to remove water droplets and oil. [Thin frame & no vignetting] The filter frame is made of lightweight aviation aluminum, and the frame is only 7.4mm thick. The thin frame design means there is no vignetting when using the wide-angle or telephoto end. *K&F CONCEPT is the world's No. 1 brand in terms of lens filter online sales volume among camera-accessory-focused brands.
