This 2-stop, 150 x 170mm NiSi Nano Soft-Edge Graduated IRND Filter is a rectangular filter that helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground. 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.

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. In order to provide a high level of color neutrality across the visible and infrared spectrums and eliminate color casts and truer blacks, 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 150 x 170mm Nano Soft-Edge Graduated IRND Filter is constructed from optical glass for clarity as well as color fidelity, and measures 2mm thick.

Q: 1. I use the NiSi 100mm Filter Holder for Nikon Z 14-24mm f/2.8 S Lens. Is this filter compatible.with that holder?

A: Yes, you can use the NiSi 100 x 100mm Explorer IRND 3.0 Filter with the NiSi 100mm Filter Holder for the Nikon Z 14-24mm f/2.8 S Lens.

Q: 2. Can it be used with NIKKOR 400mm f/2.8 TC VR S Lens which has a drop in filter holder in the back? If not, what are the options?

A: The NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (46mm) is incompatible with the Nikon NIKKOR Z 400mm f/2.8 TC VR S Lens. Instead, get the Kase Tele Drop-In Filter Kit for NIKKOR 800mm f/6.3 VR S and 400mm f/2.8 TC VR S Lenses (1.5 - 5 Stop Vari ND Filter, Magnetic Holder), BH #KAFKNZVND15.

Q: 3. 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: 4. Does this come with gasket already attached?

A: Yes.

Q: 5. Does the filter has IR CUT?

A: According to the manufacturer, yes, the NiSi 82mm True Color ND-VARIO Pro Nano 1-5 Stop Variable Neutral Density Filter does have infrared IR cut properties built into the filter.

Q: 6. can this be used with the tilta mirage matte box?

A: Round screw on filters like the NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter are supported by the Tilta Marage Matte-Box when using the correct ring attachment. The following ring will support 82mm screw on filters. However, a much better choice is the Tilta VND which is made for the Mirage Matte-box.
