Lens Filter Variable FADER ND2-400 67mm for Phone Apexel

The Apexel Lens Filter Variable FADER ND2-400 67mm for Phone Apexel is an adjustable neutral density filter designed to give smartphone photographers precise control over light transmission. With a variable density range from ND2 to ND400 and a 67mm mounting thread, this FADER ND enables longer exposures, smoother motion blur, and wider-aperture shooting in bright conditions when used with compatible phone lens adapters. The filter is intended for videographers and photographers seeking exposure control and creative effects without changing multiple fixed-density filters.

Advantages

The variable ND2–ND400 range provides a broad continuum of light reduction in a single filter, removing the need to swap filters for different lighting situations. A 67mm thread offers compatibility with many adapter rings and step-up adapters used for phone lens systems. The adjustable design allows fine-tuning of exposure and shutter speed for both stills and video, enabling smooth motion effects and better control of depth of field in bright environments. The compact form factor is practical for mobile setups and reduces gear complexity.

Suitable for

• Smartphone videography requiring controlled exposure and consistent shutter speeds
• Long-exposure photography on phones to create motion blur (water, traffic, clouds)
• Landscape and outdoor photography in bright light when wider apertures are desired
• Time-lapse sequences where light reduction extends exposure intervals

Key specifications

• Variable density range: ND2 to ND400 (adjustable light transmission)
• Mounting thread diameter: 67 mm
• Intended use: smartphone photography with compatible lens adapters
• Primary functions: exposure reduction, motion blur enablement, aperture control in bright conditions
• Form factor: slim circular filter suitable for mobile photography rigs

How to use

Attach the filter to a compatible phone lens adapter or step-up ring with a 67mm thread. Rotate the outer ring of the variable filter to adjust the density between ND2 and ND400 while monitoring exposure on your phone screen or external app. For motion blur effects, use slower shutter speeds and experiment with different densities to obtain the desired streaking or smoothing. For video, set a consistent shutter speed and adjust the filter to maintain correct exposure without changing ISO or aperture settings.

Usage recommendations

When mounting the filter, ensure it is securely threaded to avoid vignetting or looseness. Start with a mid-range ND setting and preview results before committing to long exposures. Use a stable support or tripod for exposures longer than a fraction of a second. Store the filter in a protective case when not in use to prevent scratches and dust. Avoid extreme rotation beyond the filter's smooth range to prevent mechanical wear.
