KF X Fader Variable ND Filter 77mm ND2-ND400 Grey

The KF X Fader Variable Neutral Density Filter is a versatile tool for photographers and videographers, allowing precise control over exposure in bright conditions. With a 77mm diameter and a density range from ND2 to ND400 (1 to 9 stops), this filter enables slower shutter speeds and wider apertures without overexposure. Crafted from high-quality optical glass with multi-layer nano-coatings, it is waterproof, oil-proof, scratch-resistant, and anti-reflective. The ultra-slim aviation aluminum alloy frame (7.4mm) minimizes vignetting, and the double-threaded design allows for additional filters or lens caps. The rotating ring adjusts density smoothly, and the filter maintains neutral color balance with minimal color shift and X-pattern elimination.

Advantages

This variable ND filter offers exceptional flexibility for creative exposure control, from subtle to extreme light reduction. Its high-quality construction ensures durability and optical clarity, while the slim profile prevents vignetting even on wide-angle lenses. The multi-layer coatings protect against dust, moisture, and scratches, making it ideal for outdoor use.

Suitable for

• Landscape photography requiring long exposures in daylight
• Videography needing consistent shutter speed and depth of field control
• Portrait photography with wide apertures in bright conditions
• Travel and outdoor photography where quick adjustments are needed
