My first book of Vincent Lambert was when I bought my D7000 and I have not regretted it. Also, having acquired the D7100, I renewed this approach. To avoid getting lost in the maze of the Nikon operating instructions, I strongly advise you to use this item. It is written in a pleasant style and the author dissects all the features of this unit and the commitment pushes you to advocate the setting of your camera. The author excellent teacher, includes photographs that correspond to different réglages.Pour beginners, it reviews the different terminologies of the photo by explaining the point by point sources and / or effects. This work is to put all hands, from beginner to connoisseur.
