77mm CPL on DA 15mm step up ring

Did anyone try to use a step down ring to make a 77mm CPL work on a 49mm lens. I have a B+W CPL that i want to use on my DA 15mm is possible. I'm not worried about CPL creating uneven skies. It will be used to remove reflections.

You need to have an extra ring between the stet-up ring and the DA15's filter ring; the built-in hood interferes with the step-up ring.

I don't have a DA15 but my roommate does, and what he did was take a regular cheap UV filter, knock out the glass, and screwed that in between the DA15 and his stepup ring (77mm).

Wouldn't the 2 rings as you are suggesting still interfere with the the hood
