Went to the Wallabies game on Saturday night, to take photos of my boy ( his team did the curtain raiser before the wallabies played) , and just before the wallabies went on the field my camera ( 5Dmk2) came up with Err 06. It said something about the cleaning system.. Anyone come across this error before?? if so, what was it? HELP PLEASE! ( feels like I've lost my right hand not being able to take photos )
