The book is very well made and well organized. Well illustrated and well explained. While many things can be on the internet, this book has the advantage of applying all the basic principles of a SLR 700D. A big negative all the same, there is too much history old EOS models (400-500-550D etc ...) Who cares how some were organized menus and buttons on previous generations of EOS. The book spends time comparing the functions of 700D with older generations. I really do not see the usefulness of these comparative innumerable. At first when buying this book is to know the functions of the 700D and not previous versions ...
