The 9-stop, 100 x 100mm NiSi Nano IRND Filter is an ND filter with a 512x filter factor that provides a 9-stop exposure reduction. Its 2.7 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 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 100 x 100mm Nano IRND 2.7 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 100mm Nano IRND 2.7 Filter is constructed from optical glass for clarity as well as color fidelity, and measures 2mm thick.

This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.

Q: 1. does this kit come with a filter holder?

A: It does not.

Q: 2. Can additional filters be added on top of the Nano 810 to stack filters?

A: There is a 67mm front thread on this filter, so you can stack filters as needed. However, there is a risk of vignetting as you add more than one filter.

Q: 3. I have been into photography for a long time but never used filters. Will this kit be too overwhelming for a beginner? Should I be just getting one individual filter than a set like this?

A: If you are ready to start using ND filters this kit is a lot more fun than using thread in filters. The image quality you will obtain is also superior compared to the quality you obtained using a thread invariable ND filter. The system is very easy to assemble and connect to your lenses.

Q: 4. Is this filter compatible with Lee Filters Foundation Kit (Standard 4x4") B&H # LEFK ?

A: Yes, this filter will fit with the Lee Filter Foundation Kit.

Q: 5. This is because I use it with the H & Y magnetic frame so that my filter cannot be sticked with sponge (for prevent light leakage). Do you know that this filter has sticked sponge?

A: I'm sorry but this filter does not have foam on the edges.

Q: 6. Would this fit a Lee holder? How is the colour neutrality vs Lee big stopper and little stopper (who high on think have too strong a colour caste)?

A: The, B+W 100 x 100mm XS-Pro MRC-Nano 815 ND 4.5 Filter (15-Stop) is one of the better ND filters. And is very good for low color cast. And yes, it will fit into the Lee 100mm holders. Like lee filters the filter is 2mm thick.

Q: 7. Will these work with V5 filter holder ?

A: Yes, these will work with the V5 or any standard 100 x 100mm / 4" x 4" 2mm filter holder system.

Q: 8. Would these work in a matte box?

A: These filters will fit in a matte box that accepts 100mm filters that are 2mm thick.

Q: 9. What filter system do you recommend/use with this filter?

A: This is a 100 x 100mm - 2mm thick filter, and one of the most popular systems for that size is the LEE Filters LEE100 Filter Holder (https://bhpho.to/2Tg0TrU)

Q: 10. Does this fit the NiSi 100mm Filter Holder for Sony FE 14mm f/1.8 GM Lens?
