Camera Filter CAMDIOX Gray Fader 67mm variable neutral density filter

CAMDIOX Gray Fader 67mm is a variable neutral density (ND) screw-in filter designed for lenses with a 67 mm thread. It enables continuous attenuation of light entering the lens, allowing photographers and videographers to control exposure and depth of field without changing aperture or shutter speed. The filter is suited for situations where reduced light is needed to achieve motion blur, manage highlights, or maintain wider apertures in bright conditions.

Advantages

The CAMDIOX Gray Fader 67mm delivers smooth, stepless density adjustment across its operating range and fits directly onto compatible lenses via a 67 mm thread. By reducing light evenly, it helps preserve color balance and contrast while minimizing the need to alter camera settings. The screw-in design provides secure attachment and compact profile for easy use in the field, and the variable function eliminates the need to carry multiple fixed-density filters.

Suitable for

• Landscape photography requiring long exposures to smooth water and clouds
• Long-exposure cityscapes and architectural shots to blur moving elements
• Video production where controlled exposure and motion blur are needed
• Portraits and shallow depth-of-field work in bright light without stopping down

Key specifications

• Filter type: Variable neutral density (ND) filter
• Mount: Screw-in ring for 67 mm lens threads
• Optical effect: Adjustable light attenuation for exposure control and motion blur
• Construction: Multi-element glass optical surface in metal housing (screw-in)
• Control: Rotating front element to change density continuously

How to use

Attach the CAMDIOX Gray Fader 67mm to a lens with a matching 67 mm thread by screwing it on until it seats securely. Frame and meter the scene as usual, then rotate the filter's outer ring to increase or decrease light reduction until the desired exposure or motion effect is achieved. When using for long exposures, use a tripod and mirror lock-up or electronic shutter as applicable. Check for vignetting at wide focal lengths and adjust composition or remove the filter if needed.

Usage recommendations

For best results, test the filter at different rotation positions before critical shoots to identify the usable density range with your lens and camera combination. Avoid stacking thick filters that can cause vignetting; when filming, monitor for color shifts or cross-polarization effects and correct them in-camera or in post if necessary.
