Any specific suggestions for Canon SX60 since it is a bridge camera (normally instructions are for other types of cameras)
Hermitibis already gave me a very good hint:
Contrary to DSLRs, these models don't count the "clicks", ie the numbers of photos shot. So it's guesswork whether a camera is little used. - Hint: The "Func set" of the SX50 is the most frequently used button. If the text "Func Set" looks brandnew, it indicates that the SX50 has had few clicks.
