Book excerpt: This book is used in conjunction with The Leica Pocket Book and Leica Price Guide and has been compiled from original Leitz sources. The book has two aims: the first is to act as the constant pocket companion for the Leica Collector in his travels; the second is to help Leica enthusiasts who want to study fascinating accessories in greater depth. It covers the whole period from 1924 to Spring 1996 and will enable the reader to place an individual accessory in its historical context with contemporary Leica models and lenses. Readers wishing to study Leica accessories further and looking for a more suitable bedside companion are referred to the author’s Leica Collectors Guide which also includes comprehensive accounts of Leitz enlargers, projectors and binoculars.
