A CONCISE GUIDE TO COLLECTING AND RESTORING VINTAGE BINOCULARS is particularly suitable for beginners who would like to build a collection of vintage or preowned binoculars and would like guidance on how to carry out their own servicing tasks. Over the years I have built a sizable collection of preowned binoculars and carried out my own repairs and servicing tasks on many of them. This book will be a helpful introductory guide to all and especially to those who may have little knowledge of collecting and servicing binoculars.
In this second edition, eight new sections have been added as follows:
A brief history
Non prismatic binoculars
Prismatic binoculars
What is light transmission?
What is the exit pupil?
What is eye relief?
What is light gathering power?
What is the optimum power - light ratio?
