Offering a 10-stop reduction in exposure, along with infrared attenuating abilities, this 40mm Tiffen XLE advantiX IRND Filter 40mm 10-Stopenables the use of longer exposure times with maintained color fidelity. By darkening the entire scene, this 3.0 optical density filter allows you to work with wider apertures or longer shutter speeds without overexposing your image, in order to better control depth of field or convey movement more easily.

The IRND design of this filter has been optimized for use with digital sensors, and works to attenuate both visible and infrared light. Digital image sensors are more sensitive to a greater range of light spectra, and as such are prone to color shifts or casts when photographing darker subjects or scenes that require increased exposure times. This filter's unique design helps to suppress false colors for greater neutrality and faithful color reproduction.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and mounting to precision metal rings.

3.0 Optical Density    ColorCore Technology    Increase Exposure Length    Greater Control Over Exposures    Attenuates Infrared Light

ND 3.0 filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

Providing a 10-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.

Attenuates infrared light, as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure lengths.

Related Questions and Answers

Q: 1. 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: 2. I bought three of these (2/4/6 stops) and only this 2 stop 4x4 doesn't fit into SmallRig Lightweight Matte Box. If all of them didn't fit I'd easily blame it on SmallRig as it's a super low level item, but apparently QC from Nisi is subpar?

A: NiSi have provided an exchange option for this inquiry.

Q: 3. What is the difference between this and the Nisi 4x4? (I read one is 2mm and the other is 4mm) what difference does that make?

A: 2mm filters are primarily used in slide-in filter holders, whereas 4mm filters would not fit them and are primarily used in matte boxes.

Q: 4. Can this be used as a drop-in filter (with the threaded drop-in) with Canon 300mm f2.8L IS USM II & 600mm f4L IS USM II lenses?

A: Yes, the Hoya HD MKII IR ND8 Neutral Density Filter (52mm) can be used as a drop-in Canon EF 300mm f/2.8L IS II USM Lens and the Canon EF 600mm f/4L IS II USM Lens.

Q: 5. 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: 6. 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: 7. 4mm glass is for Nisi V5 system?

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

Q: 8. What is the warranty on this product?

A: NiSI filters come with 1 year warranty in the US only. They are distributed through Ikan Corp in Texas.

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

A: Yes.
