K&F Concept Nano-C HMC Fader ND2-400 Variable ND Filter 67mm

The K&F Concept Nano-C HMC Fader ND2-400 is a high-quality variable neutral density filter designed for photographers and videographers who need precise control over exposure. With a variable density range from ND2 to ND400 (1 to 8.66 stops), this filter allows you to achieve long exposures and shallow depth of field even in bright conditions. The 67mm diameter fits a wide range of lenses, and the ultra-slim 5.2mm frame minimizes vignetting on wide-angle lenses.

Advantages

This filter offers exceptional versatility, allowing you to adjust the light reduction smoothly without changing filters. The Japanese AGC optical glass with HMC (Hard Multi-Coating) and nano-coating ensures high light transmission, minimal color shift, and protection against water, oil, and scratches. The aviation aluminum alloy frame is durable yet lightweight, making it ideal for outdoor and travel photography.

Suitable for

• Landscape photography: Capture silky waterfalls, smooth clouds, and motion blur in daylight.
• Long exposure photography: Achieve exposures of several seconds or minutes for creative effects.
• Video production: Maintain a wide aperture for shallow depth of field in bright environments.
• Architecture and cityscapes: Reduce glare and control reflections.
