Pros & Cons
👍 Pros
- 6-stop light reduction enables long exposures in bright daylight without overexposure.
- IR coating blocks infrared contamination that causes unwanted color shifts in other ND filters.
- Nano-coated optical glass resists water, dust, and fingerprints for easier field maintenance.
- 100x100mm square format fits standard holder systems and works across multiple lens diameters.
- Foam gasket helps prevent light leaks between the filter and the holder during long exposures.
👎 Cons
- 100x100mm size requires a separate filter holder system, adding cost and setup time.
- 6-stop reduction may not be sufficient for very long exposures in bright midday light without stacking.
- Optical glass construction makes the filter more fragile than resin alternatives and requires careful handling.
- Premium NiSi pricing places it above budget ND filter options.
Frequently Asked Questions
How many stops of light does the NiSi IR ND64 filter reduce?
The ND64 provides a 6-stop (1.8 density) reduction, allowing you to use shutter speeds 64 times longer than without the filter, which is ideal for smoothing water, clouds, and other motion effects.
What filter holder system does this 100x100mm NiSi filter fit?
This square filter is designed for 100mm filter holder systems. NiSi makes compatible holders, and it also fits most third-party 100mm holders from brands like Lee and Cokin Z-Pro with proper adapters.
Does the NiSi IR ND64 cause a color cast?
NiSi's IR ND filters are designed to block infrared light contamination, which is a common cause of color cast in neutral density filters. This results in more accurate, neutral colors compared to standard ND filters.
What is the nano coating on this filter for?
The nano coating repels water, oil, and dust from the glass surface, making the filter easier to clean in the field and reducing ghosting and reflections that can degrade image quality.
Can I stack this ND64 with other filters?
Yes, 100x100mm square filters can be stacked in compatible holders. Combining the ND64 with other ND or graduated filters lets you achieve greater light reduction or balance exposure across the frame, though heavy stacking may introduce slight vignetting on ultra-wide lenses.
