Lens Filter CAMDIOX Gray Fader 55mm - variable neutral density for exposure control

CAMDIOX Gray Fader 55mm is a screw-in variable neutral density (ND) filter that fits lenses with a 55 mm front thread. It provides continuously adjustable light attenuation to reduce exposure without altering color balance, allowing photographers and videographers to maintain preferred aperture and shutter speed settings in bright conditions. The filter is intended for controlling exposure, creating motion blur, and achieving shallower depth of field when required.

Advantages

The variable ND design replaces the need to carry multiple fixed-density filters, offering smooth transition between light reduction levels. The filter’s optical glass construction maintains image clarity while reducing light uniformly across the frame. Its 55 mm screw mount ensures secure attachment and compatibility with lenses that share the same thread size. The compact, single-filter form factor simplifies setup and switching between different exposure settings on location.

Suitable for

• Landscape photography in bright daylight to allow longer exposures for motion blur effects.
• Portraits and shallow depth-of-field work where wider apertures are desired in strong light.
• Video recording to control shutter angle/speed and maintain cinematic motion under varying light.
• Street and travel photography when rapid adjustment of light reduction is needed without changing lenses.

Key specifications

• Filter type: variable neutral density (adjustable ND)
• Mount diameter: 55 mm screw-in thread
• Optical element: multi-coated glass for reduced reflections and improved contrast
• Light attenuation range: continuously variable to allow control over exposure (specified by stops on the product packaging)
• Finish: slim profile to minimize vignetting on standard and wide-angle lenses

How to use

Attach the CAMDIOX Gray Fader 55mm to the front of a compatible lens by screwing it onto the 55 mm thread until it is secure. Compose and meter the scene, then rotate the front element of the filter to increase or decrease the density until the desired exposure, shutter speed, or aperture balance is achieved. For long-exposure effects, select a smaller aperture or longer shutter speed and adjust the filter to achieve the intended light reduction. When using the filter on wide-angle lenses, check for vignetting and, if necessary, use a slim-profile version to reduce corner darkening.

Usage recommendations

Use the CAMDIOX Gray Fader 55mm to maintain optimal aperture and shutter speed control in bright environments; avoid extreme rotation positions that can introduce cross-polarization artifacts. Store the filter in its protective case when not in use to preserve the multi-coating and glass surface.
