I have a FujiFilms FinePix S3100 and I have a lens question.

I have a few 37mm screw based lenses I would like to use on this camera. It comes with a 55mm step up ring already, but I can't find what size the out rinng around the zoom lens is. Like the width of the screw part of the step up lens is.

How can I make my 37mm screw lenses work on this?

Thanks,
Tim
