The 7D is an engaging and efficient housing, but it is also complex, its manual generally done well, such as Canon manuals usually lack even sometimes when clarity. The book by Luc Vincent, moreover well written and fun to read, does not solve everything, but it has the merit to bring the views, comments and explanations from a professional who will help illuminate these points obsurs . Personally I enjoyed: - The technical explanations in support positions, although sometimes difficult (eg dynamic light) they are understandable thanks to the drawings, - The author takes vis-à-vis the 7D distances not hesitating to criticize when it deserves, for example facing competition (Nikkon) more efficient on some points, - The author also distances himself sometimes stating: "Some photographers are like this, or Canon offers this, personally I prefer to do differently because ..." - It twists easily to the neck forums drifts even some journalists where assertions that spread often lack a little serious analysis. Practically: - He brought me theoretical knowledge supplements on certain points, - It led me to modify some settings that I had adopted, - It allowed me to get into the uses that I had not considered, eg computer control with EOS utility CONCLUSION: It is perfectly "Mastering the canon EOS 7D" without Luc Vincent but if you are like me, a photographer who rediscovered the photo with digital, there is something valuable time, avoiding sometimes traumatic failures in wildlife photography the "check mark" rarely rings 2 times!
