The 2-stop, 100 x 100mm NiSi Nano IRND Filter 100x100mm 2-Stopis an ND filter with a 4x filter factor that provides a 2-stop exposure reduction. Its 0.6 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 0.6 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 0.6 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.

A: The NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (82mm) rear threads are 82mm, and the front threads, where the rotating lever is, are 86mm.

Q: 5. 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: 6. Does this come with gasket already attached?

A: Yes.

Q: 7. What is the front filter thread MM diameter?

A: The NiSi 95mm True Color ND-VARIO Pro Nano 1-5 Stop Variable Neutral Density Filter has a front 95mm size thread.

Q: 8. Does the filter has IR CUT?

A: According to the manufacturer, yes, the NiSi 82mm True Color ND-VARIO Pro Nano 1-5 Stop Variable Neutral Density Filter does have infrared IR cut properties built into the filter.

Q: 9. Does the filter have a threaded front element to allow for additional filter be threaded on the front?

A: The NiSi 82mm True Color ND-VARIO Pro Nano 1-5 Stop Variable Neutral Density Filter has 86mm front threads. The 86mm front filter thread is larger than the rear thread to reduce the chance of vignetting on wide-angle lenses. It is recommended that this filter is used on 35mm or longer focal lengths lenses.
