Chinese filter manufacturer, NiSi, announced a 5 to 9 stops variable ND filter today, the ND-Vario 5-9 Stops Pro Nano filter. It is a variable neutral density filter that provides an exposure reduction of 5 to 9 EV (stops). The density, or ND factor, is controlled by turning the filter and it’s step-free.
This filter features built-in hard stops at both end positions. Those stops should make it easier to determine your relative location when rotating the front ring.
The filter provides better control over the amount of light that hits the sensor. Which in turn, allows for wider apertures and/or longer shutter speeds. Hopefully, this will make the filter useful to both photographers and videographers.
The filter features an advanced nano-coating which, according to Nisi, will repel water, grease, and dirt and makes the filter easier to clean. Nisi also claims that wide-angle lenses will suffer no vignetting due to a thin filter ring.
For the best possible results, Nisi recommends using the variable ND filter on lenses with a focal length of 35mm or more (full-frame).
Nisi says that this probably is the only ND-vario filter on the market with up to 9 stops, and that without any “cross-effects” or color cast. The company is already offering a NiSi Vario ND 1,5-5 EV filter.
