The 77mm M2 Magnetic Quick Swap Filter 5-Pack from Freewell combines five popular filters in one convenient kit for photographers of all levels. These filters mount magnetically in just seconds without using threads. Multiple filters may be stacked for more creative control. The kit has a mounting ring that mounts on any camera lens with a 77mm front filter thread. It also includes a magnetic front cap with a convenient holder.
Each filter is made from premium German optical glass and is multicoated to reduce flare and optimize light and color transmission. In addition, each filter features a layer of protective coating to make it scratch-resistant, waterproof, dustproof, and oil-resistant. This makes them ideal for use in harsh environments and also easy to clean. The slim magnetic mounting rings make the filter resistant to vignetting, even on wide-angle lenses.
