I bought this product 3 weeks ago and in the first week I loved to click photographs from this camera as everyone would love to click pics after spending a huge amount on camera. But that did not long last, I was using the camera the otherday and I found that Auto focus is not working. I tried whole day to set the settings so that Auto focus would work bt it did not work. I contacted canon for the issue and then issue was resolved after a week. Now I am using it like before with Auto focus
