The NiSi JetMag Pro Magnetic Adapter Rings are designed to be used with the JetMag system.
Simply screw the adapter ring to the front thread of your lens, the JetMag filters then magnetically attach and twist lock in place. Now you can quickly swap filters to create the desired look for your images.
An aluminium construction makes the adapter ring durable, and the slim design prevents vignetting in your images.
