An old pic from the archives as my 40D is showing the ERR99 code!
I've done everything suggested on various sites - changed the battery,
changed the CF card, cleaned the contacts, changed the lens (using Canon
lenses)... without taking the camera apart don't know what else to do!
Has anyone else had this problem & if so, what did you do?!
It's still under warranty so I think I'll be packaging it up & sending
it off to the service centre to be cleaned & serviced! Good job I
have my old 400D hanging around!
Cream cakes last year!
