Freewell Magnetic Quick-Swap Glow Mist Overview The 112mm Magnetic Quick-Swap System Glow Mist 1/2 Camera Filter screws onto lenses with a 112mm filter thread and accepts filters from Freewell's Magnetic Filter System. The optional filters can magnetically be swapped in and out. Installation is simple; no more threading. You can now switch your filter in two to three seconds with the quick-swap magnetic system. The Glow Mist 1/2 Density Filter highlight flares are controlled adding a soft light pastel effect. Made of high-definition premium optical glass, it is double-sided and multicoated, with zero chromatic aberration (color shift). Each side of the glass element is waterproof, dustproof, scratch resistant, and oilproof to make sure you are ready for all the elements.
