The 2-stop, 150 x 170mm NiSi Nano Hard-Edge IRND Filter 150x170mm 2-Stopfrom NiSi has a rectangular shape and helps darken specific areas of an image, such as bright skies, while allowing for normal, unaffected exposure in other parts of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the dense and clear areas. A neutral density filter with a hard-edged line of transition is particularly useful for images that feature a prominent horizon, or any hard transition between the sky and land. Neutral density filters do not affect the coloration of the image and this filter provides up to a 2-stop reduction in light from entering the lens.

Constructed from optical glass for clarity as well as color fidelity, this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. To provide a high level of neutrality across the visible and infrared spectrums to eliminate color casts and ensure cleaner, truer blacks, 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 filter is 2mm thick and fits most filter holder systems that are 150mm wide.

Useful for images that feature horizons, or any hard transition between the sky and land.

Filter does not affect coloration of the image and is ideal for use with other filters.

Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure times.

Related Questions and Answers

Q: 1. Could this be used for video? We are hoping to use a Canon XF105 to livestream the upcoming solar eclipse.

A: Yes, the NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter can be used for video as well as photography.

Q: 2. will this fit in a drop in filter tray for canon L glass, like the 200-400 f4? Provided you take off the thumb stud.

A: Unfortunately, the NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (52mm) will not fit in that lens. To fit in a drop-in filter holder, the filter needs to be very thin, the front has to be the same diameter as the back, and the filter cannot have the knurling on the outside of the filter.

Q: 3. 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: 4. Will this VARIO Pro Nano help with IR pollution for the Blackmagic cameras?

A: No, it will not. The NiSi 77mm True Color ND-VARIO Pro Nano 1-5 Stop Variable Neutral Density Filter does not have infrared (IR) cut capability. For cinema cameras like the Blackmagic cameras, NiSi recommends their solid ND Neutral Density filter line which has IR reduction such as the NiSi 77mm PRO Nano IRND or NiSi 77mm HUC PRO Nano IRND filter lines.

Q: 5. when the 6-9 ND comes out, can it be COMBINED with the 1-5 (=14)? with threads or friction: will i need 86mm to put with 82 1-5?

A: No, you can not combine the NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (82mm) with another variable nd filter.

Q: 6. 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: 7. I am going to use this filter on my 60-600mm lens. Doesn't X-effect occur at any focal length?

A: The NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (105mm) does not create an X pattern at all. An "X" pattern tends to happen on lower end variable ND filters that cover a broader stop range such as 2 to 8 stops.

Q: 8. Is this filter compliant with ISO 12312-2 (the international safety standard for filters for direct viewing of the Sun)?

A: ISO 12312-2:2015 is the standard for direct viewing of the sun; the NiSi Solar Filter Pro Nano UV/IR Cut ND100000 Filter (77mm, 16.5-Stop) specifically states that "This filter is not appropriate for direct solar observation with the naked eye, and should exclusively be used for photographic purposes." This filter is not rated for direct viewing of the sun.

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. 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.
