What is VariND?
Variable ND filter is constructed using two polarizing filters. When rotating, they cut off more light. Using this allows it to stay more lightweight. Instead of carrying multiple ND filters, you can use just one, and adjust it depending on the situation you will approach. A lot of filters on the market allow for almost full closure of the variable ND. With infinite rotation, they go almost to black. In theory, it is a benefit but in practice, it ends up being very problematic.
Firstly due to the construction of variable ND filters, the more it closes, there are more artifacts added to the image, loss of sharpness and color too. Irix VariND filters are designed to work with the range of 2-5 stops – to keep color rendition and sharpness of the picture unchanged.
