## Long description

The K&F 67mm 2-in-1 Black Diffusion 1/4 + CPL Clip-on Lens Filter for Phone combines a subtle softening diffusion with a circular polarizer in a single clip-on accessory. It is intended for smartphones that accept 67mm thread accessories or for use with the included clip holder. The Black Diffusion 1/4 element reduces contrast and softens highlights to produce gentler skin tones and less harsh specular highlights, while the CPL element reduces surface reflections and increases color saturation and sky contrast. The combined filter is designed for mobile photography and videography where compactness and quick attachment are required.
Advantages
The integrated 2-in-1 design saves time by providing diffusion and polarization without changing filters. The clip-on mounting allows fast, tool-free installation and removal on most smartphones. The Black Diffusion 1/4 element offers controlled softening that preserves subject detail while reducing glare from bright highlights. The CPL layer improves image color depth and reduces unwanted reflections from water, glass and foliage, which is useful for outdoor scenes and portraiture.
Suitable for
Smartphone portrait photography to soften skin highlights
Outdoor landscape and sky photography to increase color saturation and reduce glare
Video capture on mobile devices where gentle diffusion and reflection control are needed
Creative shooting that requires fast switching between natural-looking diffusion and polarization
Key specifications
Filter type: combined Black Diffusion 1/4 + Circular Polarizer (CPL)
Mounting: clip-on holder for smartphones (compatible with devices that accept 67mm thread accessories via adapter or have physical clearance for the clip)
Optical effect: softening of highlights, contrast reduction, reflection suppression, enhanced color saturation
Material: optical-grade coated glass elements and metal/plastic frame for the clip (as supplied by manufacturer)
Compatibility: designed for mobile phone cameras using 67mm thread adapter or clip mounting
How to use
Attach the clip to the smartphone camera aligning the filter element over the lens, or mount the filter on a 67mm adapter if your phone case or adapter supports a threaded accessory. Rotate the CPL element while viewing the scene until unwanted reflections are minimized and the desired color saturation is achieved. Use the diffusion side to soften highlights for portraits or soften specular highlights in video; if stronger diffusion is required, remove and replace with a different diffuser. Remove the clip when not in use to avoid vignetting on wide-angle lenses.
Usage recommendations
For best results, set the phone exposure manually where possible and combine the CPL adjustment with small changes in shooting angle to control reflections. Inspect the frame for vignetting at very wide focal lengths and reposition or remove the clip if necessary. Clean the optical surfaces with a soft microfiber cloth before shooting to avoid artifacts.
