K&F ND2–ND32 Neutral Density 58mm Clip Filter Lens for Smartphone (Model SB11170)

The K&F ND2–ND32 Neutral Density 58mm Clip Filter Lens for Smartphone is a clip-on optical accessory that provides adjustable light reduction for mobile photography. With a variable density range from ND2 to ND32 and a 58mm threaded mount, this filter lets photographers control exposure without changing camera settings or aperture. It is supplied with a clip mount that aligns the filter over a smartphone camera for stable attachment and portability, making it suitable for landscape, long-exposure and motion-blur creative techniques on mobile devices.

Advantages

This clip filter offers a continuous ND range enabling gradual control of light transmission from light reduction to strong attenuation, which helps achieve longer shutter speeds and softer motion blur. The 58mm thread compatibility supports use with standard 58mm optics and adapter rings, while the clip mount ensures quick installation and removal without tools. Optical glass construction and neutral color balance preserve natural tones and minimize color cast, and the compact design suits on-the-go shooting with smartphones.

Suitable for

• Smartphone landscape photography in bright daylight
• Long-exposure mobile shots to smooth water or show motion blur
• Using wider apertures in bright conditions to achieve shallow depth of field look
• Time-lapse and creative motion studies with mobile cameras

Key specifications

• Filter type: Variable neutral density (ND2 to ND32)
• Thread size: 58 mm
• Mounting: Clip-on attachment for smartphones
• Material: Optical glass element with metal/plastic frame (model dependent)
• Light transmission control: Continuous adjustable density range
• Colour balance: Neutral (designed to minimise color cast)
• Portability: Compact and lightweight for mobile use

How to use

Attach the clip mount to your smartphone so that the filter element aligns centrally over the camera lens. Rotate the filter or adjust its control ring to set the desired density between ND2 and ND32 while monitoring exposure on the camera screen. For long-exposure or motion-blur effects, choose higher ND values and use a stable support such as a tripod or stable surface to reduce camera shake. When finished, remove the clip and store the filter in its protective case to avoid scratches.

Usage recommendations

Use lower ND settings (ND2–ND8) for modest exposure reduction and creative aperture control, and higher settings (ND16–ND32) for pronounced long-exposure effects. Combine the filter with steady support and, where possible, a remote shutter or timer to minimise vibration during longer exposures. Check alignment on multi-camera smartphones to ensure the clip does not obstruct additional lenses.
