I just checked a box of film, and the speed is shown as "100/21 ISO". The "100" is ASA. The "21" is DIN. The combination is ISO.
Ditto what Marc said. I have film (in my freezer) dating from the late fifties. The early film lists: ASA 25, DIN 15 Later films list: ISO 25/15 Meaning... ASA 25, DIN 15. And here's a table that shows exactly that. http://www.film.project-consultant.net/html/asa_din_iso.html Jim --- 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
