Easy to Install. You attach the NiSi S5 150mm Circular Polarizer Filter Kit for Sony 12-24mm to the Sony FE 12-24 f/4 G by sliding its adapter ring over the lens’s integrated hood and using the screw-in locking pin to secure it in place. Once you’ve installed the kit’s filter holder over the adapter ring, you can independently rotate the entire filter holder kit 360°, letting you use graduated neutral ND filters and other filters that are enhanced by changing their positions.
