NiSi Filter Swift System FS ND Kit (8+64+1000) 40.5-49mm

NiSi Filter Swift System FS ND Kit (FS ND8+FS ND64+FS ND1000) – Quick-change, stackable ND filters for 40.5–49mm lenses

Change or stack ND filters quickly with the NiSi Swift FS ND Kit. The three included ND strengths (3, 6 and 10 stops) slide on and off the Swift system for fast adjustments on set or in the field. You can use these filters for both photography and video to control exposure and the amount of light entering the lens for each scene.

Fast, simple filter changes and stacking

The Swift FS ND filters push on for rapid mounting and removal. You can also stack filters when needed, which lets you combine light reduction for longer exposures or wider apertures than the current lighting would otherwise allow.

Full-spectrum neutral color

These are Full-Spectrum ND filters designed to preserve neutral colors and capture true-to-life images. The kit uses different colored frames so you can identify filter strengths at a glance:

• Blue = FS ND8 = 3 Stops
• Green = FS ND64 = 6 Stops
• Orange = FS ND1000 = 10 Stops

Compatibility and vignette guidance

The NiSi Swift FS ND filters are compatible with all filters in the NiSi Swift system. The kit includes adapter rings so the same Swift FS ND filters can be used on multiple lenses with different filter threads.

Vignetting guidance for Full Frame lenses when using the Swift FS ND filters:

• One NiSi Swift FS ND filter can be used on lenses down to 16mm focal length without vignetting.
• Two stacked NiSi Swift FS ND filters can be used on lenses down to 17mm focal length without vignetting.
• Three stacked NiSi Swift FS ND filters can be used on lenses down to 19mm focal length without vignetting.

Durability, coating and design

The filters use an advanced nano coating that repels water, grease and dirt, making them easier to clean. The thin filter ring reduces the risk of vignetting on wide-angle lenses. In addition, the ring is made from high-quality aluminum to keep the filter light and strong.

Adapter rings and available sizes

The kit includes NiSi Swift adapter rings that allow lenses with different filter threads to accept the same Swift FS ND filter size. The Swift system is available for lenses with filter threads from 40.5 mm up to 95 mm.

FAQ

Question: Can I stack these NiSi Swift FS ND filters?

Answer: Yes. The Swift system supports stacking, and the kit lists vignette guidance when using one, two or three filters on Full Frame lenses.

Question: Which filter threads can this kit fit straight out of the box?

Answer: The kit includes adapter rings for 40.5 mm, 43 mm, 46 mm and 49 mm filter threads, so you can use the same Swift FS ND filters on lenses with those threads.

Question: How do I identify the ND strength quickly on set?

Answer: Each filter frame uses a different colour: blue for ND8 (3 stops), green for ND64 (6 stops) and orange for ND1000 (10 stops), which makes identification fast and reliable.

Question: Will these filters cause vignetting on wide-angle lenses?

Answer: The Swift FS ND filters use a thin filter ring to minimize vignetting. The product specifies safe focal lengths on Full Frame for one, two and three filters to help you avoid vignetting.

Question: How do I keep the filters clean during shoots?

Answer: The filters feature an advanced nano coating that repels water, grease and dirt, making them easier to clean when maintenance is required.
