Clean the Freewell DJI Mavic 3 Filters Hard Stop Variable ND like a camera lens. Use an air blower first to remove dust or sand, then wipe gently with a clean microfiber lens cloth. Avoid rubbing grit across the glass, because that can mark the coating and show up in bright skies or night lights.
Store the filter in its case when it is not on Mavic 3. Keep it away from loose keys, tools, batteries, or cables in your bag. Before each shoot, check both sides of the glass for fingerprints, especially if you are filming toward the sun, over water, or under strong city lights.
