KF Filtro ND variable X-Fader 40.5mm ND2-ND400 gris

The KF X-Fader Variable Neutral Density Filter is a versatile tool for photographers and videographers, allowing precise control over exposure and depth of field. With a 40.5mm diameter and adjustable ND2 to ND400 range (1-9 stops), this filter is ideal for achieving smooth motion blur or shooting in bright conditions without changing shutter speed or aperture.

Advantages

Variable ND design eliminates the need for multiple fixed ND filters, saving space and cost. The ultra-slim aviation aluminum frame minimizes vignetting, while multi-layer nano-coating repels water, oil, and scratches for lasting clarity. Neutral color balance ensures natural tones with minimal color shift.

• Landscape photography with long exposures
