The NiSi ND-VARIO Pro-Nano Enhanced Variable ND 1.5-5 stops and 5-9 stops are variable neutral density filters providing an exposure reduction of 1.5 to 5 stops or 5 to 9 stops. The degree of density is easily controlled by rotating the silver knob. The transition of density occurs smoothly which allows the photographer or videographer to adjust exposure length to the exact amount required for a given scene. For those using this filter with cinema or video cameras, combined adjustments of aperture and this filter allow fine adjustments of the depth of field while retaining the designated frame rate.
What does a variable ND filter do?
A variable neutral density filter blocks the quantity of light coming through the camera. Since it is variable, you can quickly and easily rotate the front ring to dial in the right exposure from 1 to 5 stops. Variable ND filters are the perfect tool for photographers wanting to get more out of long exposures and for videographers wanting to control the light when shooting.
Why use a variable ND filter?
For photographers and videographers, an ND Vario filter lets you quickly adjust the exposure without switching filters since multiple stops are already built in. Using a variable ND filter, you’ll be better able to capture scenes where the light is shifting. A variable ND filter can also help you save money as you won’t need to buy separate filters with different strengths.

Should I buy a fixed or variable ND filter?
If you’re a landscape photographer, you may prefer a fixed ND filter that is more suitable for shooting wide angle images.
If you’re a videographer, photojournalist or travel photographer, a variable neutral density filter may be more appealing because of its speed, flexibility and convenience. You’ll be able to achieve shots you wouldn’t normally be able to get.
A variable ND filter gives you more bang for your buck as you can avoid buying multiple fixed ND filters at different strengths. If you're unsure which type of ND filter best suits your needs, contact NiSi for advice.
