It features a convenient fader mechanism for smooth adjustments and a universal clip system for easy attachment to various smartphone models.

Advantages

This neutral density filter provides precise control over shutter speed and aperture settings on mobile devices, enabling the creation of motion blur effects in water or clouds and shallow depth of field in bright sunlight.

The included mounting clip ensures secure and rapid installation on most smartphones, making it a portable solution for content creators on the go.

Suitable for

• Mobile landscape photography in bright daylight

• Achieving motion blur effects on waterfalls, rivers, and moving traffic using a phone
• Shooting with wider apertures in bright environments for a shallow depth of field

When it may not be suitable

This filter may not be suitable for use with specialized smartphone cases that add significant thickness or uneven contours around the camera lenses, as the clip might not align properly. Additionally, users requiring extreme light reduction beyond 5 stops will need a higher-density filter.

Key specifications

• Light reduction capability of 1 to 5 stops
• Fader mechanism for adjustable exposure control
• Includes a dedicated smartphone mounting clip
• Designed for mobile photography and video applications

How to use

Attach the universal clip to your smartphone, carefully aligning the glass filter element directly over your phone's primary camera lens. Ensure the clip is firmly seated to prevent any shifting during use. Open your camera application and rotate the outer rim of the filter to adjust the neutral density level from ND2 to ND32 according to your lighting requirements. Adjust your camera settings to achieve the desired exposure before capturing your photos or videos.

What to consider before purchase

• Verify compatibility with your specific smartphone model and camera placement
• Check if your current phone case interferes with clip-on accessories
• Consider your typical lighting conditions and whether an ND2-ND32 range meets your creative needs
