K&F Concept 37MM MV36 Slim Variable ND Filter ND8ND2000

The K&F Concept 37mm MV36 Slim Variable ND Filter (ND8ND2000) provides 3 to 11 stops of adjustable light reduction, allowing precise control over exposure in bright conditions. Made with Japanese optical glass and 24-layer multi-resistance coating, this green-coated filter is waterproof, scratch-resistant, and features a slim, aviation-grade aluminum frame.

This filter is ideal for photographers and videographers who need precise exposure control under bright light conditions. Offering a variable optical density of 0.3 to 3.3 (equivalent to 3 to 11 stops of light reduction), it darkens the entire image evenly, enabling slower shutter speeds or wider apertures without overexposing. This allows for creative motion blur effects, especially in flowing water, or refined depth of field control to isolate subjects. Constructed from premium Japanese AGC optical glass and coated with 24 layers of multi-resistant coating, the filter delivers excellent light transmission and color fidelity while being waterproof, oil-resistant, and scratch-resistant. Its slim 7.5mm aviation-grade aluminum alloy frame ensures minimal vignetting and features a convenient density scale for precise adjustments. Perfect for landscape photography, video work, and bright outdoor shooting, this variable ND filter combines durability, quality, and versatility in a compact form.
