NiSi Filter Circular For S6 ND8 (3Stop)

NiSi Filter Circular For S6 ND8 (3Stop) – 3-Stop Neutral Density for Slower Shutter Speeds and Wider Apertures

This NiSi Circular ND8 is designed for use with the NiSi S6 150mm filter holder system and provides a 3-stop (0.9 density) reduction in exposure. Use it when you want to slow your shutter speed or open your aperture beyond what the ambient light normally allows.

Mounting and compatibility

The filter screws into a NiSi S6 150mm filter holder adapter ring after you remove the kit’s included Pro Screw-In Circular Polarizer Filter. If you plan to use this filter with an older generation S5 adapter, note that the S6 holder frame must be used in combination.

Why use a 3-stop ND8?

The 0.9 density of the ND8 darkens the entire image, so you can photograph with a wider aperture or a slower shutter speed than normally required. As a result, you gain control over depth of field and can convey motion more easily in your images.

For example, the ND8 3-stop is commonly used for waterfalls and capturing water flow at shutter speeds from 0.5 seconds to 2 seconds. In addition, ND filters help when the contrast between highlights and shadows is too high to achieve a quality exposure.

Optical quality and coatings

NiSi ND filters do not affect the coloration of the image and offer true-to-life color reproduction. The filter is made from high-quality optical glass (not resin) and uses a nano coating to preserve detail.

Because using a neutral density filter makes the camera more vulnerable to infrared light — which can cast an unwanted red color at small apertures — NiSi ND filters include an infrared protection coating layer to eliminate infrared light passing through the lens and restore natural colors.

Additionally, NiSi’s proprietary Pro Nano Coating helps reduce unwanted reflections and provides a waterproof and scratch-resistant surface. This coating also makes it easier to clean fingerprints, dust, and water stains from the filter.

FAQ

Question: Will this ND8 fit directly into my NiSi S6 holder?

Answer: Yes. The filter is designed to screw into the NiSi S6 150mm filter holder adapter ring after you remove the kit’s Pro Screw-In Circular Polarizer Filter.

Question: Can I use this filter with an older S5 adapter?

Answer: You can, but only when the S6 holder frame is used in combination with the older S5 adapter. The S6 holder frame must be part of the setup for correct fit and use.

Question: Will the ND8 change my image colors or cause a red cast at small apertures?

Answer: NiSi ND filters are manufactured to preserve true-to-life color and include an infrared protection coating to prevent infrared-induced red color casts, especially at smaller apertures.

Question: How do I maintain the filter and keep it clean?

Answer: The NiSi Pro Nano Coating makes the surface waterproof and scratch-resistant, and it eases cleaning of fingerprints, dust, and water stains. Wipe gently with a suitable microfiber cloth and cleaning solution when necessary.
