As of today, Canon has replaced the sensor on my camera but they say it's still making the lines that it did with the first one. According to Chris in Irvine, they are having problems getting the camera to "talk" to the diagnostic computers they use and have no real means of diagnosing the problem. So, even though there are no lemon laws for camers in the U.S. I'm going to give them two more weeks to get their act together, making it an entire month, and then push them very hard for a new camera, which, according to Chris, they don't have. I'm a very patient person, but it's not looking great.
