These 4 old Cannon product guides are all in very good condition. They cover details on cameras, accessories, Movie cameras, lenses and other information. One product guide is a single double sided page. The other are small books with 41, 48 & 62 pages, all printed in Japan. I am not sure of the era but they are nice reference books for the camera enthusiast. The 3 books measure approx. 15cm X 8.5cm (H). Please view all photos as they form part of the description. Thank you
