K&F Smartphone Lens Filter ND2–ND32 67mm Clip (model SB11169)

The K&F Smartphone Lens Filter ND2–ND32 67mm Clip is an adjustable neutral density filter designed for mobile photography and video. It reduces light entering the smartphone camera across a continuous range from ND2 to ND32, enabling longer exposures, controlled motion blur, and wider aperture simulation under bright conditions. The filter mounts via a clip with a 67 mm adapter, compatible with lenses or clip-style camera setups that accept this diameter.

Advantages

This ND2–ND32 filter provides variable attenuation in a single, compact unit, removing the need to carry multiple fixed-density filters. The clip-on 67 mm adapter simplifies attachment to many smartphone camera arrangements and helps maintain optical alignment during shooting. By reducing exposure without affecting color balance, the filter supports smoother video exposure and expanded creative control for mobile photographers.

Suitable for

• Long exposure photography with smartphones
• Creating motion blur effects in daylight
• Recording video with controlled shutter and exposure
• Simulating shallow depth of field by allowing wider apertures

Key specifications

• Adjustable neutral density range: ND2 to ND32
• Mount type: clip-on with 67 mm adapter
• Intended use: smartphone photography and videography
• Optical function: continuous light attenuation without color cast
• Form factor: compact, portable filter element with clip mounting

How to use

Attach the clip to your smartphone camera so the 67 mm adapter centers over the lens, ensuring the filter sits evenly and does not vignette the image. Rotate the filter element to select the required ND strength within the ND2–ND32 range; check the exposure and white balance on your device before shooting. For long exposures or motion blur, use a tripod or a stable surface to minimize camera movement. For video, monitor exposure while adjusting the filter to maintain consistent brightness and avoid abrupt changes in shutter speed or ISO.

Usage recommendations

When using the ND2–ND32 filter, verify compatibility with your smartphone camera layout and test different attenuation levels to find the optimal balance between shutter speed, ISO, and aperture simulation. Use additional stabilization for multi-second exposures and confirm focus after attaching the clip to ensure sharp results.
