NiSi Filter IRND 64+CPL Pro Nano 77mm

NiSi Filter IRND 64+CPL Pro Nano 77mm – 6-stop IRND plus Circular Polarizer in one

The NiSi Filter IRND 64+CPL Pro Nano combines a 6-stop neutral density (ND) filter with a circular polarizer (CPL) in a single 77mm filter. You don’t need to stack a CPL on top of an ND filter. The design maintains sharpness and avoids color cast, while minimizing the risk of vignetting.

Key features

• Gives you 6 stop ND effect
• No color cast for a true color matching
• IR coating and optical glass
• Waterproof, grease-proof
• Ultra High Definition glass, no visible loss of details and sharpness
• Ultra Slim Frame of only 4.9mm to reduce light falloff

What this filter does for your workflow

The combined CPL and ND design lets you use two filter functions in one element. As a result, you avoid stacking a circular polarizer on top of a separate ND filter. This reduces bulk on the lens and lowers the chance of vignetting while keeping image sharpness intact. The filter preserves true colors thanks to its low color cast characteristics.

Durability and optical quality

The NiSi Pro Nano features optical glass with an IR coating. It resists water and grease, which helps keep the glass cleaner during shoots. The Ultra High Definition glass aims to preserve details and sharpness so you don’t see visible loss in image quality when using the filter.

Design details

The frame is ultra slim at 4.9mm. This reduced thickness helps to diminish light falloff at the edges and further lowers the risk of vignetting, especially when used on wide-angle lenses. The filter’s 77mm thread size fits lenses with a matching thread.

FAQ

Answer: No. This product combines a CPL and a 6-stop ND in one filter, so you don’t need to stack a separate CPL on top of an ND filter.

Question: Will the filter cause vignetting on wide lenses?

Answer: The ultra slim 4.9mm frame reduces light falloff and helps prevent vignetting, which is a common issue when stacking multiple filters.

Question: Does the filter change the colors in my images?

Answer: The filter is designed to have no color cast, providing true color matching so your images retain accurate colors.

Question: How does the filter hold up in the field?

Answer: The IR coating and optical glass offer high image quality, while waterproof and grease-proof properties make the filter easier to keep clean during shoots.
