Camera Filter CAMDIOX Fader Grey 77mm

CAMDIOX Fader Grey 77mm is a screw-in neutral density filter for lenses with a 77 mm thread that offers continuously adjustable grey attenuation. The filter allows photographers and videographers to reduce light entering the lens without changing aperture or ISO, enabling longer exposures, controlled motion blur, and smoother video shutter control. The slim metal frame mounts directly to compatible lenses and provides variable light reduction across a useful range.

Advantages

The adjustable design provides granular control over exposure and motion effects, removing the need to carry multiple fixed-density filters. Built for direct screw-in mounting, the filter maintains optical alignment and minimizes vignetting on wide-angle lenses. Constructed with neutral density glass, it preserves colour balance while allowing precise adjustment of light transmission for stills and video applications.

Suitable for

• Long-exposure landscape photography
• Controlling motion blur for waterfalls and clouds
• Video shooting requiring lower shutter speeds or wider apertures
• Outdoor portraiture in bright conditions where shallower depth of field is desired

Key specifications

• Filter type: Variable neutral density (adjustable grey)
• Mount: Screw-in, fits 77 mm lens thread
• Frame: Slim metal construction to reduce vignetting
• Optical element: Neutral density coated glass to preserve colour fidelity
• Use: Suitable for still photography and video

How to use

Screw the CAMDIOX Fader Grey 77mm onto a lens with a 77 mm filter thread until it seats securely. Rotate the front element to change the density and observe exposure changes in the viewfinder or on the camera monitor. For long exposures, combine the filter with a tripod and low ISO; for video, adjust the filter to match desired shutter speed while monitoring highlights and motion rendering. Avoid stacking thick filters to reduce risk of vignetting.

Usage recommendations

When working at extreme densities, check autofocus and metering performance as some camera systems may require manual exposure adjustments. Store the filter in a protective case when not in use and clean the glass with lens-safe fluids and a microfiber cloth to maintain optical quality.
