This is exactly what it says it is. The manual that comes with the 60D has all the information you need but doesn't tell you WHY you need it or what possibilities each option affords. The expanded guide does all this with good illustrations and is written in everyday language. If you want to get the most from this amazing camera this book will help both as a readable walk through and as a reference. If you want to learn how to take great photos you need a different book. It is just small enough to slip into your camera bag too.
