K&F CONCEPT Filter 49Mm Black Mist 1/4 & Variable Nd2-Nd400 2-In-1 Multifunctional (Nano-Xcel Series)

2-in-1 Filter: This filter functions as both a variable ND filter and a 1/4" black mist effect filter. It not only regulates the amount of light entering the lens by adjusting the aperture (1-9 f-stops), but also creates a cinematic, dreamlike effect for photos and videos. Note: New and old packaging will be shipped randomly. Multi-coating: The surface of the K&F Concept filter features a 28-layer nano-coating, which not only effectively reduces reflections on the filter surface and avoids problems such as glare, but is also anti-mold, waterproof, scratch-resistant, and oil-resistant. High-quality glass: Made from AGC Japanese optical glass, polished on both sides, no compromises in the sharpness of telephoto lenses to ensure high-resolution images. Adjustable: The ND2-ND400 filter offers 9 continuously adjustable dimming levels for quick adjustment of the light intensity. The orange handle makes adjustment easy, quickly switching between minimum and maximum settings. No vignetting: The frame is made of aircraft-grade aluminum with an ultra-wide-angle structural design and a thickness of only 7.6 mm, which is convenient for you to avoid vignetting at the wide-angle end of the 16 mm lens. The surface is designed with a CNC trapezoidal pattern, which increases rotational friction and is convenient for installation and removal.
