Neewer 2-in-1 Variable ND2-ND32 & CPL Filter 37mm No X Cross 30 Layer Nano Coated HD Optical Glass Ultra Slim Aluminum Alloy Frame

This Neewer 2-in-1 filter combines variable ND and CPL effects, allowing you to control exposure and reduce reflections simultaneously. The variable ND2–ND32 filter reduces the light entering the lens by 1–5 stops, enabling slower shutter speeds and wider apertures for creative motion blur in various lighting conditions. Featuring self-locking technology, this filter ensures no dark cross or vignetting, even when shooting with wide-angle lenses. The circular polarizing (CPL) filter effectively reduces unwanted reflections and glare from surfaces like glass and water, enhancing image quality. It also boosts contrast and saturation, making photos of blue skies, clouds, water, snow, and glass buildings more vibrant.

Crafted from premium HD optical glass with 30 layers of nano coatings on both sides, it boasts reflectivity of less than 0.1% to minimize flare and ghosting. These multiple resistant coatings also make the filter water, oil, anti-static, and scratch resistant, ensuring durability and easy cleaning. The frame is made from CNC machined aluminum alloy with a non-slip texture for easy installation and removal. Laser-etched marks allow precise control of light reduction from ND2 to ND32. Its ultra-slim design is compatible with all lenses with a 37mm thread size (please confirm your lens thread size, typically marked with a "Ф" symbol).
