This 15-stop, 150 x 150mm NiSi Nano IRND Filter 150x150mm 15-Stopis an ND filter with a 32,000x filter factor that provides a 15-stop exposure reduction. Its 4.5 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time or increasing your aperture, you are able to control the depth of field and convey movement more easily. Neutral density filters won't 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 150 x 150mm Nano IRND 4.5 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 150 x 150mm Nano IRND 4.5 Filter is constructed from optical glass for clarity as well as color fidelity, and measures 2mm thick.

Q: 1. 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: 2. 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: 3. Are these the same glass as that found on their cine versions?

A: I contacted NiSi concerning your inquiry. According to the manufacturer, yes, the NiSi 77mm HUC PRO Nano IRND 1.8 Filter (6-Stop) uses the same optical grade glass as used in their standard square filters and their Cinema line filters. They state the only filters in their inventory that use B270 Schott glass would be the filters in their 100mm wide Explorer line, which are not available in the circular format.

Q: 4. 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: 5. 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.

Q: 6. will this allow me to use my lens hood (canon RF 28-70 F2.0) ?

A: Yes, one can use the hood from the Canon RF 28-70mm f/2 L USM Lens with the NiSi 95mm True Color ND-VARIO Pro Nano 1-5 Stop Variable Neutral Density Filter. You would need to remove the rotating lever from the filter, as that would get in the way,

Q: 7. Does this come with gasket already attached?

A: Yes.

Q: 8. 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: 9. Does this filter fit inside Tilta Mini Matte Box 82mm adapter ring?

A: Yes.

Q: 10. I have a mirrorless camera that I had converted for IR photography; regular ND filter do not have any effects on exposure; I want to shoot IR with long exposure, will this NiSi IRND do the job?

A: No, the NiSi 82mm PRO Nano IRND 3.0 Filter (10-Stop) would not be compatible for your usage needs. It does the opposite of what you are looking for; it is designed to block IR to the extent that there will not be infrared pollution when taking a long exposure. As an alternative, the filters in the NiSi Swift FS ND Filter Kit (82mm), B&H # NIRFSNDSWK82, are designed to pass all wavelengths of light evenly, so this would also be an alternative for your usage needs. Also, as standard neutral density filters pass along infrared light unless it specifically indicates it has IR reduction, a filter such as the Hoya ProND EX 1000 Filter (82mm, 10-Stop), B&H # HOPNDEX1T82, should also work for your usage needs. https://bhpho.to/3ieQ30o https://bhpho.to/3LZm8bn
