ASA-DIN on my Ikoflex

6 years 1 month ago #572129 by DirtyWater
I recently bought a Zeiss Ikon Ikoflex 1C TLR manufactured from 1956-1960. The adjustable film speed dial that the built-in light meter uses to calculate aperture and exposure has values in both ASA and DIN that correspond with each other when the dial is moved. The problem I'm facing is the values seem to be different according to today's film speeds. The speed on an ISO  100 (ASA) speed film has a DIN listed of 21 degrees. When I turn the knob on the camera to 21 degrees, the ASA reads 40. Something is clearly not right. As I understand it, DIN was reworked in 1960 to reflect a change in the ASA standard. Could this be the reason the values on my camera don't match today's film speeds? If so, if there a conversion chart or something I can use to get the old and new ASA/DIN values? Any and all help and advice is appreciated. Thanks

Ignore the din and match the camera's asa with the film's....

Why so serious?
