To read and understand the contents of this book must have full control of the operating instructions or accept constantly juggle with the two which is not great practice. It has the advantage of being a valuable addition to the manual and not a restatement (advantage / disadvantage) It is aimed at experienced photographers, as is the case indeed. But for others reading can be laborious! The tips and tricks are significant. But what displeases me most is the systematic breaking of Canon in favor of Nikon. I read this criticism before buying and I did not believe that ... I already have several book V Luke, I had not seen that. But for the 7D is heavy ... constantly denigrate the choice of Canon and enhance the performance of its Nikon equipment! I think this kind of perspective is very boring in a No Response Photos for instance. Not in a work intended for readers who have a 7D in hand, have made this choice and do not ask him to share but to better use and understand.
