NiSi Swift Add On Kit for NiSi 72mm Swift True Color VND 1-5 Stops (4 Stop ND + Black Mist 1/4)

The NiSi Swift Add-On Kit extends an existing NiSi 72mm Swift True Color VND 1-5 Stop filter with two additional press-on filters — a 4-stop ND16 and a Black Mist 1/4 — pushing the system's total range up to 9 stops of combined filtration. Both add-ons press directly onto the front of the True Color VND without extra hardware, and an included adaptor ring lets either filter mount straight to the lens on its own when the variable ND isn't needed. High-definition optical glass and nano-coating keep images clear and distortion-free across the stacked combination.

• Extends VND Range to 9 Stops: Adds a 4-stop ND16 and Black Mist 1/4 on top of the existing 1-5 stop True Color VND.
• Press-On Stacking Design: Both filters mount directly to the front of the True Color VND with no extra hardware.
• Standalone Adaptor Ring Included: Mounts the ND16 or Black Mist directly to the lens without the VND filter attached.
• No Vignetting Through 18mm/20mm: Stays clear of vignetting at 18mm with one filter stacked, or 20mm with both.
• Complete Kit: Includes the ND16 (4-Stop), Black Mist 1/4, adaptor ring, lens cap, and case.
