how to tell diameter lens adapter camera Sony Dsc-H1?

I have a camera Sony DSC-H1, and want to buy some additional filters and lenses, as such, I know what the diameter of the lens of my camera. Are there any non-Sony lenses or filters fits nicely into DSC-H1?

The screw thread diameter lens will be shown around the edge of the lens as a number preceded by what appears to be an "o" with a diagonal line through it. The filters, etc, with the size of the screw in.
