NiSi SWIFT VND Kit

The NiSi SWIFT system is engineered to minimize the cross-polarization effect, or 'X' pattern, that plagues many variable NDs. While it performs exceptionally well across its 1-9 stop range, it is always best practice to avoid pushing the filter to its absolute maximum limit if you notice any slight unevenness.

The system uses a push-on design that allows you to quickly stack the VND with the included fixed ND element. You simply press the additional filter onto the front of the base VND, which saves you from having to unscrew and re-thread filters when lighting conditions change rapidly.

No, that is the primary benefit of the 'True Color' technology used here. It is specifically designed to maintain neutral color balance, meaning your footage or photos won't take on the warm or cool tints common with lower-quality variable ND filters.

Yes, the NiSi SWIFT system is designed to be compatible with standard lens caps. Because the filter mounts securely, you can keep it on your lens during downtime without needing to remove it to cap your glass.

This filter is generally safe for most standard focal lengths, but if you are shooting with an ultra-wide-angle lens, you should be mindful of potential vignetting. Because the SWIFT system adds thickness to the front of your lens, stacking multiple elements can sometimes cause dark corners on very wide glass.
