I've had the camera one week and have read the book cover to cover during that time. Every question I had on the camera was covered in the book. After one week I feel I am using about 80% of the camera's capabilities. I doubt I would be up to 30% using the booklet which came with the camera. I keep the book in my camera bag as a reference (the index is great). Kinda hard to do that with a DVD. This book has shortened my learning curve and is highly recommended.
