The 100 x 150mm NiSi Nano Soft-Edge Graduated IRND Filter 100x150mm 2-Stopis 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. To provide a high level of neutrality across the visible and infrared spectrums to eliminate color casts and ensure cleaner, truer blacks when using the NiSi 100 x 150mm Nano Soft-Edge Graduated IRND 0.6 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 100 x 150mm Nano Soft-Edge Graduated IRND 0.6 Filter is constructed from optical glass for clarity as well as color fidelity, and measures 2mm thick.

Q: 1. I have the V5 set. If these have the gasket pre-installed, can they be stacked or used in the outer slots with one in the nearest slot?

A: You cannot stack more than 1 filter in each slot.

Q: 2. is there a particular reason Nisi makes this density in 100x100mm and not 4x4? I need 8 stop ND to complement my Nisi IRND set

A: You can use 100x100 filters. 100x100 is the same as a 4x4 filter.

Q: 3. Does this filter fit on Lee filter holder ?

A: Yes.

Q: 4. I need an additional adapter glass to use an additional 4x4 ND filter in my v5 filter box. Does this come with the adapter glass? If not, how can I get one?

A: This will work in a Nisi V5 without an adapter.

Q: 5. Schneider sells IR cut filters rated for 750nm and 680nm respectively. Do we know at what infrared wavelength this filter begins to cut light?

A: This filter does not cut light at specific nm, but cots down the light by 6 stops compared to what is available at the time of shooting.

Q: 6. Will this filter work in a Lee Foundations filter holder?

A: Yes it does

Q: 7. Do I need holder as well and I used 24-120 and 20mm most if time which one will be fit?

A: You will need a filter holder and step-up or step-down rings depending on your lens filter thread size.

Q: 8. Will this fit a Lee Filter holder?

A: Yes.

Q: 9. Is the gasket pre-installed?

A: Yes, the gasket is attached to the filter.

Q: 10. Does this have the scratch resistant coating which was demonstrated at NAB 2016?

A: Scott, these particular NiSi filters do have a scratch resistant coating, BUT, it is not the same as what was demonstrated during NAB 2016. NiSi has a new line of filters with a very strong scratch-resistant coating coming out later this year. That is what was being demonstrated at NAB 2016.
