Thanks for the info. On the page it states:

"6. Does the adapter itself create a flash shadow?
Not under normal circumstances, but when the flash is used in very close range at the wide angle setting - less than 3' with the 58mm adapter (either the Lensmate 58mm or Canon LA-DC58E, they're dimensionally identical), and less than 1' with the 52mm adapter, a small amount of flash shadow from the edge of the adapter can be seen."

I should take the time to do some measurements. I sit better than ten feet from a wall, and shoot using the wide angle lens, and loose a third of my image to shadow. They say their adapter is identical to the one I got from Canon, only it is aluminum.

This Powershot S3 IS has given me five good years of service, so it is time to graduate up to a more professional model now that I understand most of the basics.
