TIAN-YA gray fader filter 46mm – variable neutral density lens filter

TIAN-YA gray fader filter 46mm is a variable neutral density screw-on filter designed for lenses with a 46 mm thread. The filter provides continuously adjustable light reduction that lets photographers and videographers control exposure and creative effects without changing aperture or shutter speed. It helps achieve longer exposures, smoother motion blur and more controlled depth of field under bright conditions, while maintaining image colour neutrality and even attenuation across the frame.

Advantages

This 46mm variable ND filter offers stepless density adjustment for precise exposure control. The screw-on design ensures secure mounting and compatibility with any lens accepting 46 mm filters. The optical glass delivers uniform attenuation to minimise vignetting and colour cast, and its compact form factor preserves lens handling and balance. It is suitable for both still photography and video work where gradual control of light is required.

Suitable for

• Long exposure landscape photography
• Creating motion blur for waterfalls, rivers and clouds
• Controlling depth of field in bright light without stopping down
• Video shooting requiring consistent shutter and aperture settings

Key specifications

• Mount type: screw-on filter compatible with 46 mm lens threads
• Filter type: variable neutral density (gray fader)
• Density range: continuously adjustable attenuation
• Optical material: multi-coated glass for reduced reflections and improved colour neutrality
• Construction: low-profile metal ring to minimise vignetting on wide-angle lenses

How to use

Screw the filter gently onto the lens front thread until it is secure but not overtightened. Rotate the outer ring to vary the density and observe the exposure change in the camera viewfinder or live view. Use a tripod for long exposures to avoid camera shake and adjust ISO and shutter speed as needed while keeping aperture constant when a specific depth of field is required. Check the frame for any unwanted colour cast or cross-polarisation effects at extreme settings and fine-tune rotation to achieve the desired balance between exposure and creative motion effects.

Usage recommendations

For best results, pair the filter with a tripod for exposures longer than a fraction of a second and use live histogram or exposure preview to set the correct attenuation. When shooting wide-angle lenses, check for vignetting at maximum density and dial back slightly if necessary. Clean the filter glass with a lens cloth before use to avoid spots or streaks in long exposures.
