This book is entirely pictorial, contains more than 120 color image, and every image, except the images of the cameras, were shot on film. These film images are just a sampling and the author has a great many more film cameras then the ones pictured herein; and they all function perfectly and are in more-or-less constant use.
There is considerable debate among photographers about whether film is better than digital with about an equal number lining up on both sides and presenting their opinions and relevant and irrelevant data. It is not the purpose of this volume to espouse one position or another. It is sufficient to know that they are each different and subject to a considerable range of interpretation.
However, it is quite enjoyable to take one of these old cameras, that have absolutely no automatic functionality, and create excellent images. I suspect that it is the same force that drives auto enthusiasts to take an old Model T Ford car and restore it. They certainly don't have the power and ease of operation of modern automobiles but they are extraordinarily fun to drive.
