The 8-stop, 100 x 100mm NiSi Nano IRND Filter 100x100mm 8-Stopis an ND filter with a 256x filter factor that provides an 8-stop exposure reduction. Its 2.4 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 2.4 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 2.4 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 fits Tilta 4 x 5.65" Stackable Filter Tray Holder (BH #TIMBT16SFH)?

A: According to Tilta, the Mirage-system supports 2mm and 4mm filters like this Nano IRND 2.1 filter. The issue with your question, however, is that the stackable filter tray holder is not the device you need to hold the filter. You need TIMBT16SFT (stackable filter tray) AND TIMBT16SFH (stackable filter tray HOLDER) to work with the Mirage matte box.

Q: 2. Would this pair well with the Nisi ND-Vario Pro Nano 1-5 stops, to create a variable 4-8 stops ND?

A: While the NiSi 72mm PRO Nano IRND 0.9 Filter (3-Stop) does have a front thread, it is not advisable to use two variable ND filters at the same time as it would create undesirable results.

Q: 3. Does this filter fit inside Tilta Mini Matte Box 82mm adapter ring?

A: Yes.

Q: 4. will this fit in to a LEE 100 system?

A: Yes. Lee systems adapts to all 4x4, 4x6 and all 100mm filters

Q: 5. 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: 6. Will this filter work in a Lee Foundations filter holder?

A: Yes it does

Q: 7. Which side should be facing away from the camera? I realize this sounds like a silly question, but since these filters appear to have identical coating on both sides, I'm curious if it should make a difference? Should I assume that the side with the engraved writing be facing AWAY from the camera? I just received 3 of these (3, 5, and 7 stop filters) and a bit dumbfounded! BTW, the quality looks fantastic, along with the packaging.

A: Since both sides have identical coating, it doesn't matter which way the filter is facing. We've taken them out on several shoots without noticing a difference either way.

Q: 8. will this fit the tilta mini matte box?

A: Yes the NiSi 4 x 5.65" Nano IRND 0.3 Filter (1-Stop) BH #NIRND034X565 • MFR #NIC-4565-ND0.3 will fit the Tiltaing Mini Matte Box BH #TIMBT15 • MFR #MB-T15.

Q: 9. 4mm glass is for Nisi V5 system?
