Where precision and versatility meet, the 37mm Circular Variable ND64-1000 6 to 10-Stop Lens Filter Plus+ stands as a high-quality choice for photographers and videographers seeking professional-grade control over their images. This durable and effective filter offers a variable density range from ND64 to ND1000, enabling 6 to 10 f-stops of light reduction. This feature allows for the use of wider apertures to achieve a shallower depth of field, or slower shutter speeds for captivating long exposure effects, even in bright and variable lighting conditions.Constructed with the world's finest German B270 Schott optical glass, this filter ensures superior clarity and light transmittance. The 20-layer nano-coating on the glass not only facilitates easier cleaning but also provides robust protection against water, oil, and scratches.
