What is the filter size and the outside diameter (for matte box) of the Fujinon WCV-82SC wideangle converter.

I cannot seem to find these two numbers anywhere.

(e.g. the standard lens is 82mm threaded and 85mm)

The converter is the same as the stock lens, 82mm thread and 85mm outside diameter (or maybe closer to 84mm). The lens hood will slide right over it, or you can use your existing matte box without issues.
