Out of the blue, I can no longer use the main dial to change the aperature or the iso. I am using AV mode. I have reset to default and removed and replaced the battery. I can change the aperature in Q.
Thank you. I did try that later, and it didn't work. I finally found the place to chat with a technician at the Canon website, and he said to send it in. It's still under warranty, but I had to pay for shipping!
