This book does a marginally better job of explaining the menus and functions than the manual that comes with the camera does. It does not offer any real world advice on how to get the most from the camera. You're still on your own. There are no recommendations, no examples of what features to use when, how to get the most from the camera in various shooting situations. It is just an slightly clearer extension of the camera manual. Only it costs about fifteen bucks and it took nearly a year to get printed after it was first listed on Amazon. The manual in the camera box is a.) included in the price of the camera and, b.) delivered on time.Save your money.
