Here are a couple good reviews of them with sample pictures, hopefully that helps you. I have owned and used several canon cameras and they have all been VERY nice. I have not yet used an olympus to know if they are good or not. Canon has been top of the line for as long as I can remember so if you want to play it safe, just get the canon.
