This book was a complete waste of $20. The EOS 7 has so many features, but very few of them are explained in this book any better than the manual. These folks should be embarassed to sell this for the price. I now know why they're sealed in plastic wrap at the bookstore -- to prevent you from actually seeing inside before purchasing... For other cameras I own, I've found the Short Course in Photography series by Dennis Curtin to be great resources. I don't think they have one on the EOS 7 however.
