I moved up from a from an older model Canon DSLR and thought that I really needed a little help in finding out what my new camera could do. This book has been very useful to me and I oiften refer back to it. I know it may not go into great detail, but I think it is really aimed at the keen amateur photographer. I needed a manual to give me a grass roots understanding of the potential of my camera and this book gave it to me. I would recommend this manual.
