This 5-stop, 150 x 170mm NiSi Nano Soft-Edge Graduated IRND Filter 150x170mm 5-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 5-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. 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: 3. 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: 4. What's the difference between Nisi Explorer and Nisi Nano IRND filter ? which one is better !

A: The Explorer model would be comprised of Schott B270 Glass for impact resistance and better clarity over the Nano model.

Q: 5. Hi, i wold like yo know if this model it's compatible with the Sony PZ28-135 mm?

A: Yes, the NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (95mm) is compatible with the Sony FE PZ 28-135mm f/4 G OSS Lens.

Q: 6. Does this go with the NiSi 82mm Swift VND Mist Kit 1-9 Stops (1-5-Stop VND, 4-Stop ND, Black Mist 1/4)?

A: The NiSi 82mm HUC PRO Nano IRND 1.8 Filter (6-Stop) can be used on any lens or filter that has an 82mm filter thread. It does not use the Nisi Swift Friction Mount System.

Q: 7. 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: 8. 4mm glass is for Nisi V5 system?

A: Nisi V5 uses 100x100mm by 2mm thick filters.

Q: 9. Does this come with gasket already attached?

A: Yes.

Q: 10. Does this filter come in a metal case similar to the 150mm Lee filters?

A: The NiSi Explorer Collection 150x170mm Nano IR Medium Graduated 3-Stop ND Filter only comes with a soft case.
