my 300D working normally, all of a sudden 2/3 of the photo is black...double check nothing blocking the lens...then try to clean the CMOS...the 2/3 of black image is gone but now the auto focus didn't work!!! okay fine, let's go to Canon for service!
the girl in Canon service center are very nice, even I arrive 7:05pm which they close at 7pm, they still open the door for me. but it take 7 days to repair the camera that I can't accept this service level.
my friends said it is time for you to upgrade!
