NiSi Swift Add on Kit 67mm

The NiSi Swift Add-On Kit for NiSi Swift True Color VND 1-5 Stops (4 Stop ND + Black Mist 1/4) is the perfect way to extend the capabilities of your NiSi Swift True Color VND 1-5 Stop Variable Filter. With this add-on kit, you’ll be able to add an ND16 (4 Stop ND) and Black Mist 1/4 filter to your system, giving you a total of 1-9 stops of filtering power.

The NiSi Swift System works seamlessly with the NiSi True Color 1-5 stop VND Variable ND filter allowing the capability to be expanded by adding extra filters simply by pressing them on the front of the NiSi True Color 1-5 stop VND Variable ND filter.

The high-definition optical glass and nano-coating on these filters will ensure that your images are clear and free of distortion, while the waterproof and anti-reflective coating will keep them looking great for years to come. Plus, the included adaptor ring makes it easy to mount the ND16 (4 Stop) or Black Mist directly to your lens without the True Color 1-5 stop VND Variable Filter. This kit includes the ND16 (4 Stop), Black Mist 1/4, Adaptor ring, Lens cap and case.

Stacking multiple filters can introduce vignetting when shooting with wider focal lengths.  See the suggested focal lengths below to avoid vignetting.
