Use of this NiSi S5 150mm Filter Holder Kit is easily accomplished by first sliding the kit's adapter ring over the integrated hood of a Tamron SP 15-30mm f/2.8 Di (VC or non-VC) USD lens or a Tamron SP 15-30mm f/2.8 Di VC USD G2 lens. While its screw-in locking pin helps to provide a reliable connection to the lens, the adapter ring accommodates the included NiSi Circular Polarizer Filter for NiSi S5 150mm Filter Holder Kits. When combined with the adapter ring, the polarizer filter can be rotated to adjust its effect. In such instances, both external dials on the adapter ring allow for the independent rotation of the circular polarizer.

The kit's filter holder can then be placed over the adapter ring. After being fitted onto the adapter ring, the filter holder's pull-and-release locking pin helps to provide a reliable, yet adjustable connection while the entire filter holder kit can be rotated 360°, permitting the use of graduated neutral density and other filters that are enhanced by varied positioning.
