This 3-stop, 67mm NiSi PRO Nano IRND Filter is an ND filter with an 8x filter factor that provides a 3-stop exposure reduction. Its 0.9 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 67mm PRO Nano IRND 0.9 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 67mm PRO Nano IRND 0.9 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.

Q: 1. 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: 2. I bought this for the ring of fire eclipe. My question is why are my pics black and white? Glasses were orange and black. Bad se

A: It is normal for the NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter and other similar filters to produce nearly monochrome images due to the density of the filter combined with the sun's brightness. Please check the reviews of other solar filters or this same filter in other sizes and you will see mostly monochrome or near monochrome photos.

Q: 3. 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

Q: 4. Can I combine this with a Nisi circular polarizer? which should be in front (which determines size i need)?

A: Yes, you can combine with NiSi circular polarizer. The size of the filter will be the same as the ND filter. The circular polarizer should be in front, after the ND filter, circular polarizer is being rotated more often then ND so should have easier access without disturbing exposure. When stacking multiple filters with rotating elements consider having Rubberized Filter Wrench https://www.bhphotovideo.com/c/product/1407950-REG/sensei_48_55mm_rubberized_filter_wrench.html of appropriate size due to possible difficulty of separating the filters when taking of the lens.

Q: 5. 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: 6. 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: 7. 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: 8. 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: 9. Aside from solar photography, will I be able to use this filter as an ND filter for long exposure photography?

A: The Solar Filter Pro Nano UV/IR Cut ND100000 Filter (77mm, 16.5-Stop) allows 1/16.5th of the available light into the camera's sensor so you can use this as a ND filter for long exposure photography as well.

Q: 10. What is the origin of the glass in the filter?

A: Unfortunately Nisi does not specify the type of glass used in the Pro Circular Polarizer Filter.
