The 82mm M2 Magnetic Quick Swap 1/4 Glow Mist Filter from Freewell offers the usual creative effects of a mist filter with the convenience of their magnetic quick-swapping system. Once the magnetic frame is screwed on to the front of your lens, different filters can be attached, removed, or swapped out quickly and conveniently. The 1/4 density glow mist adds atmosphere to your images by subtly lowering your contrast and softening the focus, producing a dreamy and nostalgic effect. The German optical glass construction and multilayer coating make the filter scratch and oil resistant as well as water and dustproof. The included filter pouch and lens cap help you further protect your filter when shooting on the go and switching between densities.
