This 3-stop, 4 x 5.65" Pancro Combination IR + ND Filter is a combination of both an infrared control filter and a 0.9 neutral density filter. An IR+ND is ideal for HD cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to IR contamination. When using a standard neutral density filter to counter the increased light sensitivity afforded by the HD sensor, the effects of infrared pollution become more apparent. This filter combines the properties of an ND filter with an IR control filter to eliminate the spill of infrared light reaching the sensor while still maintaining the extra exposure benefits of a neutral density filter.

This filter offers a flat spectral curve ranging from 380nm to 2000nm. This neutrality enables Pancro ND to filter out troublesome IR wavelengths in the 800nm to 2000nm range that are frequently captured on HD cameras.

The glass itself is a single piece of non-laminated material that offers excellent flatness, minimal distortion, and durability.

0.9 Optical Density    Enables Use of ND Without IR Pollution    Maintains Color Fidelity    Ideal for HD Cameras

Infrared control filter helps to block infrared pollution from affecting the color fidelity of imagery; this enables a wider color gamut and truer colors, especially noticeable in the darker regions of the image.

0.9 neutral density filter provides a 3-stop exposure reduction.

One-piece, non-laminated construction offers a high degree of flatness, minimal distortion, and durability.

Q: 5. is this appropriate for shooting solar eclipses?

A: Yes, the NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (67mm, 16.5-Stop) can be used for solar eclipse shots. Note, it is not safe for direct viewing of the Sun.

Q: 6. How much reduction in UV and IR spectrum, respectively, is specified? I understand the reduction in visible light is 16.5 stops.

A: Unfortunately, Nisi does not specify how much of the IR and UV is reduced for NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (77mm, 16.5-Stop). They do state that the UV and IR cut is to offer a color neutral result. Therefore the UV and IR cut should not be relied upon for anything else other than offering an image that is color neutral.

Q: 7. Using this filter and a tracker can the camera be left pointing at the sun for long periods without damaging sensor or lens?

A: Yes, there should be no issue using the NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (95mm, 16.5-Stop) with a tracker when photographing the solar eclipse.

Q: 8. Which solar filter is for the Nikon 400 mirrorless lens?

A: The Nikon NIKKOR Z 400mm f/2.8 TC VR S Lens can use the Tiffen Solar ND Filter (46mm, 16-Stop), B&H # TI46ND48. Note, it is not ISO 12312-2 certified. It should not be used to look directly at the sun with our eyes. It can be used for the camera to take a photo of the sun. Look only in the LCD live view to compose the photo. Do not look in an optical viewfinder.
