In general manual of this collection do not deserve this name "for Dummies". In this case it is entirely appropriate, you really never have had a camera in hand to find something interesting in this book. I do not recommend it in any case to a possessor of this great device if he wants to know how to handle it so efficace.Soit it is a connoisseur and after having traveled, he will ask for a refund foutage of mouth, or he is a novice and I first recommend him to start with the photo and if D7100 he really wants to know one day use to read the manual that comes with it.
