OK Rol_Lei Nut, now the OP at least knows how you arrived at your one line comment but it would have been helpful if you'd said from the start that you believe that all AF systems are faulty in more than 50% of cases and this is based on your experience and an article on DSLRs.

If APUG is going to be useful in threads where the OP is seeking information then we all need to know why someone has said what he/she has said.
