Variable Neutral Density Camera Filter K&F Concept 72 mm Fader ND2–ND2000 Gray (KF01.2445)

The Variable Neutral Density Camera Filter K&F Concept 72 mm Fader ND2–ND2000 Gray (KF01.2445) is an adjustable gray filter designed to reduce the amount of light entering a camera lens with a 72 mm thread. The fader ND design allows continuous control of light transmission from approximately 1 to 11 stops, enabling longer exposures or wider apertures in bright lighting without changing ISO. The filter features a nano coating to help repel water and reduce reflections, making it suitable for outdoor photography and video shooting.

Advantages

This 72 mm variable ND filter offers stepless attenuation from ND2 to ND2000 for precise exposure control across a wide range of scenes. The gray neutral density element preserves color fidelity while reducing light, and the nano coating improves durability and ease of cleaning. Its screw-in design fits lenses with 72 mm front threads, providing a compact and quick solution for controlling shutter speed and aperture without carrying multiple fixed ND filters.

Suitable for

• Landscape photography with long exposures (smooth water, motion blur)
• Videography to maintain cinematic shutter angles in bright conditions
• Portraits or shallow depth-of-field work in strong daylight
• Time-lapse sequences requiring controlled exposure over varying light

Key specifications

• Filter type: Variable neutral density (fader ND)
• Filter size: 72 mm screw-in thread
• Density range: adjustable from approximately ND2 to ND2000 (about 1–11 stops)
• Coating: nano coating for reduced reflections and easier cleaning
• Color: gray neutral density element to preserve color balance
• Mount: slim circular frame designed for general-purpose use on compatible lenses

How to use

Screw the filter onto the lens front thread (72 mm) until secure, taking care not to cross-thread. Rotate the outer ring to adjust the neutral density level and monitor exposure using the camera's meter or live view. For long exposures, set the camera on a stable tripod and use mirror lock-up or electronic front curtain if available. When using wide-angle lenses, check for vignetting at the maximum density and consider stopping down or using a slim filter frame if needed.

Usage recommendations

Avoid extreme overlap of polarizing filters and variable NDs to reduce the risk of uneven darkening. Store the filter in its case when not in use, and clean with a soft microfiber cloth after shooting in dusty or wet conditions to maintain the nano coating performance.
