K&F Concept Filtro ND variable ND8-ND128 67mm

The K&F Concept Variable ND8-ND128 Filter is a high-quality neutral density filter designed for photographers and videographers who need precise control over exposure. With a variable density range of ND8 to ND128 (3 to 7 stops), this filter allows you to achieve long exposures, smooth motion blur, and shallow depth of field even in bright conditions. The 67mm thread size fits a wide range of lenses.

Advantages

This variable ND filter offers exceptional versatility, reducing the need to carry multiple fixed ND filters. The 28-layer multi-coating ensures minimal color shift and high light transmission, while the ultra-slim aviation aluminum alloy frame prevents vignetting on wide-angle lenses. The knurled edge provides easy grip for smooth rotation, and the filter is designed to minimize the X-pattern effect at maximum density.

Suitable for

• Landscape photography with long exposures
• Portrait photography with wide apertures in bright light
• Videography requiring consistent shutter speed
• Any lens with a 67mm filter thread
