In 1963, prior to the introduction of 126, 127 was the most popular film format, period. But once Kodak introduced the Instamatics, people stopped buying 127 format cameras. Yes, Kodak continued making 127 film for many years after that (Ektachrome was discontinued around 1984) but that is only because there were millions of these cameras already in circulation- but very few were sold after 1963. The main difference between 126 and 127 is, of course, the film loading method being much easier and simplified in the newer format. Both were generally square format. 35mm was not a primary amateur format in 1963. Most people shot very few pictures and if you had a 36 exposure roll in the family camera, you were likely to see pictures for more than one Christmas when developed. After the demise of 127, there were no more such traditional roll films aimed at amateurs. The Instamatics killed it. --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list
