## Long description

The Lens Filter Black Diffusion 1/4 Clip-On for Smartphone 67mm K&F SB11313 is a clip-mounted diffusion filter designed to soften highlights and reduce contrast for mobile photography and videography. It provides a quarter-strength diffusion effect that creates mild bloom around bright areas while preserving detail and color balance. The filter mounts quickly to a smartphone using an adjustable clip and is compatible with lenses or lens adapters featuring a 67 mm thread diameter.
Advantages
This clip-on diffusion filter delivers controlled softening without heavy loss of image sharpness, making it suitable for portraits, cinematic video, and creative mobile imagery. The 1/4 diffusion strength produces subtle highlight bloom and smoother skin tones while maintaining natural color rendition. The clip mounting system enables fast attachment and removal, offering portability and convenience for on-the-go shooting.
Suitable for
Smartphone portrait photography to soften skin and highlights
Mobile videography for cinematic highlight roll-off and reduced contrast
Creative on-location shoots where mild diffusion is desired
Use with lens adapters or mobile lenses having a 67 mm thread
Key specifications
Filter type: Black diffusion, 1/4 strength
Mounting: Clip-on for smartphones (adjustable clip)
Compatible thread diameter: 67 mm
Effect: Mild softening with highlight bloom and reduced contrast
Optical characteristics: Preserves overall detail and color balance with minimal sharpness loss
How to use
Attach the filter to your smartphone camera by positioning the clip so the optical element aligns over the lens and tightening the clip for a secure fit. If you use a lens adapter or an external mobile lens with a 67 mm thread, screw the filter onto the thread and then fine-tune alignment. Frame and expose as usual; you may need to adjust exposure slightly to compensate for the diffusion effect in very bright conditions. Remove the filter when maximum sharpness or unaltered contrast is required.
Usage recommendations
For portrait work, position the filter to soften facial highlights while keeping eyes in focus; for video, test white balance and exposure with the filter attached to ensure consistent results. Store the filter in a protective pouch when not in use to avoid scratches on the optical surface.
