Query: A Good Introduction

Not complete, but a good start for mostly pre-1945 cameras and lenses. The sections on bellows restoration and construction alone probably make this book a worthwhile purchase. Tomosy illustrates restoration techniques using specific cameras and lenses that are mostly common and relatively inexpensive. A couple of different Kodak Brownie cameras are two of the cameras examined in the chapter on folding cameras, for example. The Exacta VX, Nikkorex 35, Zeiss Contaflex, and Leica II are some of the models examined in the 35mm chapter. Other chapters cover Lenses and Lens Shutters, Wooden View Cameras, Large-Format Focal-Plane Shutters, Medium Format, and the Minox C. What keeps this from being 5 stars is Tomosy's too casual treatment of wood-, metal-, and leatherworking on a couple of his projects. However, he does include an appendix about tools, lubricants, parts suppliers, and other suggested readings.
