KF X Fader filtro ND variabile 37mm ND8-ND128 grigio

The KF X Fader Variable ND Filter 37mm ND8-ND128 is a high-quality neutral density filter designed for photographers and videographers who need precise control over exposure. With an adjustable ND range from ND8 to ND128 (3 to 7 stops), this filter allows you to achieve slower shutter speeds and wider apertures even in bright conditions, enabling creative effects like motion blur and shallow depth of field.

Advantages

This variable ND filter offers exceptional versatility by combining multiple ND densities in one slim, rotating frame. The Japanese AGC optical glass with 28 multi-layer coatings ensures minimal color shift and eliminates the X-pattern issue common in variable ND filters. The aviation aluminum alloy frame is ultra-slim and double-threaded, allowing you to attach additional filters or a lens cap.
