This 15-stop, 82mm NiSi PRO Nano IRND 82mm 15-Stop Filteris an ND filter with a 32000x filter factor that provides a 15-stop exposure reduction. Its 4.5 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters are intended to not affect the coloration of the image and are ideal for pairing with other filters.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. To provide a high level of neutrality across the visible and infrared spectrums in order to eliminate color casts and ensure cleaner, truer blacks when using the NiSi 82mm PRO Nano IRND 4.5 Filter, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces. The Nano coating associated with this filter also results in an improved beading effect when in contact with water or oil for greater cleaning efficiency.

This NiSi 82mm PRO Nano IRND 4.5 Filter is constructed from optical glass for clarity as well as color fidelity, and features a brass filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention.

Related Questions and Answers

Q: 1. 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: 2. 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: 3. Would this work for the upcoming full solar eclipse?

A: Yes, the NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter can be used for the upcoming solar eclipse.

Q: 4. Could you provide a more specific nm range for this, or is the spectrum available?

A: Unfortunately, ND filters like the Solar Filter Pro Nano UV/IR Cut ND100000 Filter (77mm, 16.5-Stop) that cut UV and IR light do not specify a nanometer range. This is because they are meant for long exposures photos without a color shift and not for IR photography.

Q: 5. 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: 6. 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: 7. 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.

Q: 8. Can the orange lens handles be removed? Thanks

A: The orange handles of the K&F Concept Nano-X Pro Series CPL+ND2-32 Filter (77mm, 1 to 5-Stop) are not made to be easily removed, but they can be removed with a screw driver (purchased separately).

Q: 9. I wish to use this filter to view the total solar eclipse. Is it good for that?

A: No, the NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (58mm, 16.5-Stop) is not designed for solar eclipse.

Q: 10. compatible solar filters for Nikon 24-70 mm f/2.8 ED VR?

A: Here are the compatible solar filters for the Nikon AF-S NIKKOR 24-70mm f/2.8E ED VR Lens. https://bhpho.to/3Ll2UwO
