The JetMag Pro MAXMAG Magnetic Adapter Ring from NiSi allows you to use MAXMAG filters on lenses with a standard 105mm front thread. It enables fast and secure magnetic attachment and removal without traditional screw-on threading. Its locking design helps keep filters securely mounted during use, including when rotating or stacking multiple filters. The slim aluminum profile is designed to minimize vignetting, supporting clean edge-to-edge results even when using wide-angle lenses.
