First Edition (1000 NUMBERED copies total). Hardcover, 13 x 9-1/4" 216 pages, 370 black & white photos. After many years of research into Canon Inc and the M39 screw mount rangefinder lenses that Canon produced between 1939 and 1971, this will be the first English-language book to go into detail on the variaties of these early lenses and the first major book on the subject since Peter Decherts 1985 "Canon Rangefinder Camera 1933-68". The book describes the various changes and markings on the lenses and explains where the lenses fit in the evolution of the early Canon lens system. It contains detailed charts on each lens to give Canon collectors a clear overview of what is in their collections. Detailed sections on the serial numbering system developed by Canon, prototypes that appear in various literatures, and rare and unusual items that Canon produced during this Golden Ageas covered, as well as detailed historical and timeline charts from 1933 to 1971 about Canon as it developed from a fledgling Seiki-Kogaku Kenkyusyo in the back streets of Tokyo into the huge multinational it is today.
