Description
The NiSi True Color ND-VARIO Variable 1-5 stops filter is the ideal tool for photographers who want to approach the world of long exposures and for videographers who want to be able to control the light in real time during shooting, without introducing any type of artefact or aberration. NiSi Filters has created a unique filter, allowing you to use a single filter to obtain a reduction of the light that enters the lens from 1 to 5 stops. The characteristics and quality of the filter avoid any “X” or “cross effect” from which variable ND filters often suffer.
The unique lens grade optical glass that made the NiSi brand famous was also used for this ND Variable. Furthermore, there is the Nano Coating treatment which makes the surface waterproof and resistant to grease and dirt. Cleaning the filters has never been easier. Screw NiSi ND Variable Nano filters are available in several popular sizes, from 40.5 to 105mm.
The front thread is one step above the rear thread: Back thread 82mm -> Front thread 86mm
Αll Vario filters are not real ND filters, but always formed by two treated surfaces that in contrast reduce the light entering the sensor. For this reason, even the best variable filter is never exempt from some small defects such as: uniformity of absorption and presence of slightly darker or lighter areas. We always recommend the use of variables as a practical alternative to ND filters and not as a total substitute. The advice of using only high quality ones such as Vario-ND NiSi remains valid. For specific uses where fixed density NDs can be equipped (and especially for focal lengths below 35mm), we recommend fixed density ND filters.
Disclaimer: Variable ND (VND) filters are constructed from two optical glass elements that rotate relative to each other. Due to this design, they are not weatherproof or waterproof. The hydrophobic (water-repellent) coating is applied only to the front and rear glass surfaces to help repel water, fingerprints, and dirt, making the filter easier to clean. It does not seal the filter against water or moisture ingress.
