I just got it and of course I still have not discovered everything. However, the browsing I already had plenty of answers to my questions about the handling of the D7100 which annoyed me seriously! Book well done, with examples and pictures to explain step by step and with tips and advice pictures as a bonus! Phew I'll finally succeed to serve me in this Nikon D7100 who took my head despite its manual. I did well to purchase this manual, I am reconciled with my material!
