<p>Hi guys. Today I recieved "Err 01" on my Cannon 600D. I cleaned the contacts with alcohol and it didnt work right away, but it might have contributed. What I did was to try to take a photo on the minimum aperture (f22), and it worked! After that I saw on some forums that other people have had this problem and resolved it in this way. Just a piece of advice :)</p>
