Ring Canon

If you buy the Canon Powershot WCDC58A broad to S5SI, you need an adapter ring, too?

Yes, you did. You must use the adapter conversion lens (LA-DC58E) if you want to use the wide angle converter, decoder or TV Close-Up lens. You can also buy the same Conversion Lens Adapter with LH-DC40 lens hood. The kit is LAH-DC20.
