This 3-stop, 52mm NiSi PRO Nano IRND 52mm 3-Stop Filteris an ND filter with an 8x filter factor that provides a 3-stop exposure reduction. Its 0.9 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. 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 52mm PRO Nano IRND 0.9 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 52mm PRO Nano IRND 0.9 Filter is constructed from optical glass for clarity as well as color fidelity, and features a brass filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention.

Related Questions and Answers

Q: 1. I am going to use this filter on my 60-600mm lens. Doesn't X-effect occur at any focal length?

A: The NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (105mm) does not create an X pattern at all. An "X" pattern tends to happen on lower end variable ND filters that cover a broader stop range such as 2 to 8 stops.

Q: 2. Can the adjustment stick be removed? I'd like to be able to fit this inside a lens hood.

A: Yes the rotating lever is removable.

Q: 3. Can a lens hood be used with this filter, specifically for a sony 24-70 2.8 v1?

A: No, the Nano-X Variable ND filter will not work on the Sony 24-70mm f/2.8 GM I with the lens hood on. Both the polarizing and variable ND knobs on the filter prevent the lens hood from mounting on the camera. If you use fixed ND filters, you can use the lens hood.

Q: 4. 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: 5. Can I get a swift 6-9nd add on filter that will fit on the front of 58m VND?

A: Nisi says that they should have a swift 6-9 ND that works with the NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (58mm) some time in October.

Q: 6. 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: 7. Can it be used with NIKKOR 400mm f/2.8 TC VR S Lens which has a drop in filter holder in the back? If not, what are the options?

A: The NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (46mm) is incompatible with the Nikon NIKKOR Z 400mm f/2.8 TC VR S Lens. Instead, get the Kase Tele Drop-In Filter Kit for NIKKOR 800mm f/6.3 VR S and 400mm f/2.8 TC VR S Lenses (1.5 - 5 Stop Vari ND Filter, Magnetic Holder), BH #KAFKNZVND15.

Q: 8. will this fit in a drop in filter tray for canon L glass, like the 200-400 f4? Provided you take off the thumb stud.

A: Unfortunately, the NiSi True Color ND-VARIO Pro Nano 1 to 5-Stop Variable ND Filter (52mm) will not fit in that lens. To fit in a drop-in filter holder, the filter needs to be very thin, the front has to be the same diameter as the back, and the filter cannot have the knurling on the outside of the filter.

Q: 9. Does it fit to rf 28-70?

A: Yes, the canon 28-70 RF features a 95mm filter ring.

Q: 10. 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.
