This 6.6 x 6.6" NiSi Nano IRND Filter is an ND filter with a 32x filter factor that provides a 5-stop exposure reduction. Its 1.5 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overxposing your image. 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 6.6 x 6.6" Nano IRND 1.5 Filter, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces.

This NiSi 6.6 x 6.6" Nano IRND 1.5 Filter is constructed from optical glass for clarity as well as color fidelity, and measures 4mm thick.

6.6 x 6.6" neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

Providing a 5-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.

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.

Leatherette pouch included for storage and transport.

Related Questions and Answers

Q: 1. Can the hard stop be removable?

A: According to the manufacturer, the hard stops on the NiSi 82mm True Color ND-Vario Pro Nano 1-5 Stops Variable ND Filter cannot be removed. If the variable neutral density filter had no hard stops, cross-type X-banding patterns would occur in your images.

Q: 2. 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: 3. Does this come with gasket already attached?

A: Yes.

Q: 4. Does the 67mm size cause vignetting when used with the Sony SEL20F18G lens?

A: No, the NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (67mm) will not cause a vignette on lenses, like the Sony FE 20mm f/1.8 G Lens (B&H # SO2018G).

Q: 5. Does this fit under the Sony 24-70 GM II lens hood?

A: The NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (82mm) will not fit the Sony FE 24-70mm f/2.8 GM II Lens (Sony E) with the hood attached.

Q: 6. Can I get a swift 6-9nd add on filter that will fit on the front of 58m VND?

A: Nisi says that they should have a swift 6-9 ND that works with the NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (58mm) some time in October.

Q: 7. Does the 43mm filter have 43mm filter threads int he front of it? Or like the 82,, does it have larger 86mm filter threads in?

A: The NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (43mm) has 43mm rear filter threads and 46mm front threads.

Q: 8. How does this "Explorer" differ from the "Nano"?

A: The explorer is also Nano but NiSi Explorer filters are constructed from tempered Schott B270 glass for shock resistance as well as increased optical clarity and color fidelity.

Q: 9. 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: 10. Will the 105mm fit the Canon CN-E 15.5 - 47mm?

A: The NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (105mm) will fit the Canon CN-E 15.5-47mm T2.8 L S Wide-Angle Cinema Zoom Lens with EF Mount.
