This 4-stop, 4 x 5.65" Pancro IR + ND Filter 4x5.65" 4-Stopis a combination of both an infrared control filter and a 1.2 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.

1.2 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.

1.2 neutral density filter provides a 4-stop exposure reduction.

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

Q: 1. Can I use this for timelapse photography of the sun? (For example, shooting the sun over the four hours of an eclipse)

A: Yes, the NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (77mm, 16.5-Stop) can be used for a long term time lapse of the sun. Just don't look at the optical viewfinder on the camera. Use the LCD live view to compose.

Q: 2. Can I use this with the nikon Z 24-70 F4? The nikon website lists diameter as 77.5.

A: The Nikon NIKKOR Z 24-70mm f/4 S Lens has a filter thread of 72mm. If you want to attach the filter directly to the lens with an adapter, you would want to get his option instead: https://bit.ly/3ujiIec

Q: 3. Will this filter work with my Sony 14mm F1.8 GM lens? I think I need the threading on the outside of the filter

A: The NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (82mm, 16.5-Stop) is incompatible with the Sony FE 14mm f/1.8 GM Lens. Instead, get the NiSi 100mm Filter Holder for Sony FE 14mm f/1.8 GM Lens, B&H # NIP100SONY14, and the NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (100 x 100mm, 16.5-Stop), B&H # NIP100ND50.

Q: 4. 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: 5. What's the difference between Nisi Explorer and Nisi Nano IRND filter ? which one is better !

A: The Explorer model would be comprised of Schott B270 Glass for impact resistance and better clarity over the Nano model.

Q: 6. Does the filter come with a case?

A: Yes, the NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (95mm, 16.5-Stop) comes with a case.

Q: 7. Will this filter give the sun a more white color or a yellowish color?

A: The NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter will produce a near white image of the sun. The yellow/orange that you see in some of the sample photos was added by the users in post.

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.

Q: 9. If this filter is NOT safe for direct eye viewing, why should I believe it IS safe for a camera's sensor? Please convince me.

A: The NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (16.5-Stop) is safe for camera sensors when used carefully and following the instructions. The sensitivities of eyes and sensors are different and what is good for one may not be good for the other. This filter has been used on cameras without causing any sensor damage.

Q: 10. What color will the sun be orange or white ? The sample photos show both.

A: The NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (77mm, 16.5-Stop) will provide the most color-neutral results. The saturation of the color is based on post image editing and/or the brightness of the sun.
