This Filter Protection Cover for the Tilta Mirage is designed to protect our 95mm Circular Polarizer Filter and 95mm Variable ND Filter for the Tilta Mirage Matte Box. This kit includes both a Front and Back Cover allowing you to easily protect your filters while they are loose or when attached directly to your lens via our Lightweight Filter Clamp-On Adapter. When a filter is attached to your lens, you can use the front cover to protect the glass from damage or scratches while traveling or moving locations without needing to detach the filter.
