How to use

Align the adapter with the front of the DJI Osmo Action 4 housing according to the adapter’s fitment features and press into place or secure as designed by the adapter. Once the adapter is attached and properly seated, screw a 49 mm filter clockwise into the adapter’s threaded opening until snug. For removal, unscrew the filter counterclockwise and detach the adapter from the camera. Ensure threads are clean and free of debris before mounting to avoid cross-threading and to maintain optical alignment.

Usage recommendations

Use compatible 49 mm filters that match the camera’s field of view to prevent vignetting. Tighten filters by hand without excessive force; if using multiple stacked filters, check for possible vignetting on wide-angle shots. After use in wet or sandy conditions, clean the adapter and filter threads with a soft cloth to prolong service life.
