Thanks for the input. I've read at least three comments about an E18 error message (though I don't think any of them came from this forum.) Some people also mentioned purple fringing on the S1 IS. I wanted to know if these two problems were wide-spread or limited occurances.

Compared to the little Hewlett Packard Photo Smart camera that my husband has now, this should be a great improvement. I'm also considering the Olympus C765. Any advice?
