In case anyone is ever in the same situation this may be of use:
The Graphic-Kowa 150mm f9 has male filter threads around the front lens element. These threads accept a 46mm step-down ring (NOT STEP-UP).
A filter can then be screwed onto the outside of the ring, using the "female" threads on the filter.
A push-on filter ring can be used, but I thought I would post this for anyone in a similar situation who wants to use threaded.
