KF X Fader Variable ND Filter 52mm ND2-ND400 Gray

The KF X Fader Variable ND Filter 52mm is a high-quality variable neutral density filter designed for photographers and videographers who need precise exposure control. With a density range from ND2 to ND400 (1 to 9 stops), it allows you to achieve long exposures and smooth motion blur even in bright conditions. The filter features Japanese AGC optical glass with 28 multi-layer coatings for excellent light transmission and minimal color shift. Its ultra-slim aviation aluminum alloy frame minimizes vignetting and eliminates the X-pattern issue common in variable ND filters. The filter is water, scratch, and oil resistant, making it durable for outdoor use. Both front and rear threads allow for stacking additional filters.

Advantages

Versatile exposure control from 1 to 9 stops, high-quality optics with minimal color shift, durable construction with water and scratch resistance, ultra-slim design to prevent vignetting, and compatibility with other filters via front and rear threads.
