The JetMag Pro 82MAG Creative Magnetic Filter Kit from NiSi allows you to take full advantage of the JetMag magnetic system by attaching, swapping, or stacking filters quickly and easily. A patented locking design is incorporated to prevent accidental detachment. The included VND filter provides a 1- to 5-stop range of exposure reduction, which extends to 9 stops by stacking the 4-stop FS ND filter. Multiple magnetic adapter rings let you use your filter on a range of different-sized filter threads. The filter caddy, back cap, and front cap help you keep your filters protected when being transported or not in use.
