Somehow I missed this until right near the end of the NAB show. Schneider have decided to bring out their own vari-ND filter solution using their high quality glass. I find vari-ND filters essential for my daily work and am really glad to see a high end solution – albeit at a higher price than existing filters.
Essentially a high quality matched pair of polarisering filters, one circular and one linear, you can vary the amount of neutral density across a claimed ten stop range. Unlike some other variable ND filters Schneider claim theirs will remain sharp on a 200mm lens (on a 5DMkII).
The set comprises a 77mm screw in circular polariser and a 4×4 linear polariser which is held in a custom Lee filter holder which allows the filter to rotate.
I have bought this kit for my personal use and hope to be doing a test soon.
