Designed specifically for the MAXMAG line, the NiSi JetMag Pro Magnetic Front Cap magnetically locks to the front of your filter, protecting it from dust, impact, moisture, and scratches. Whether packing up after a shoot or moving between locations, it allows photographers and filmmakers to work quickly without fumbling with traditional snap-on caps. Lock the front cap to the adapter ring or directly to a filter by aligning the cap handles with the JetMag Pro locking indicators, which ensures the cap will remain firmly in place. Built from durable and lightweight aluminum, it fits neatly into camera bags without adding unnecessary bulk.
