Canon M 39 Rangefinder Lenses, 1939-1971 Book
Ordered the book on the 29th March and received it just over a week later on the 7th April - half way round the world to the UK!
Peter - the book is an astonishing achievement. Beautifully bound and presented, the detailed information on each lens (and version) is as complete as anyone could wish for.
Quite simply, the book is definitive on the Canon rangefinder lens era.
