Received very quickly by Amazon. Thank you !! This book completes the manual and dailleurs there often refers. The difference is that it offers a more practical approach to the possibilities of the Canon EOS 500D that manual. More educational course, but also more critical (independence requires). Jai sometimes been frustrated to learn absence functionality ("this is a shame, as it has no") when I just wanted to take advantage of my camera. Otherwise it is a good free, complete and very useful but a bit heavy for lemmener on holiday;)
