Hoya Variable ND Filter - 72mm
Variable ND (Neutral Density) Filters have been around now for well over a decade. When they originally came out we were super excited. The notion of buying just one ND filter that covers a wide range of FStops is of course brilliant. It is arguable that the image quality is diminished from a Hoya ProND Filter (which covers just one stop down of say ND32 (5 stops) or ND64 (6 stops) so please bear that in mind in your buying decision.
PLEASE NOTE. If you turn the Variable ND filter to the extremities, you can expect to get a cross effect. Back the filter off a bit and live with it as it is.
Get the flexibility of a variable ND filter with Hoya's ND option. This one has a 72mm thread.
