SmallRig 1/4 Black Mist Square Filter for Smartphones

SmallRig Square 1/4 Black Mist Filter attaches quickly to your phone via a dedicated mounting base (sold separately). The base is precision-engineered to fit the phone's camera module, serving both as a filter mount and a shield for daily lens protection. It can be used directly on the bare phone or with most cases featuring large camera cutouts.

This square magnetic filter is made from optical glass with multi-layer nano-coating to ensure pristine, uncompromised image quality. It attaches instantly and securely to the base, enabling seamless creative control and allowing you to capture every moment with precision.

Note:
• Do not stack more than two filters on the 0.5x ultra-wide lens. If dark edges (vignetting) appear, adjust the filter's alignment
• The magnetic attachment is not a mechanical lock. Do not use during high-vibration or high-speed airflow activities such as cycling, with car mounts, or on roller coasters
