ISO 50 and ISO 160 for Zeiss Ikon

[drjoke]

How do propery set that for ZI?

The closest I can get is 33, and 167.

Sorry, how have you determined these values? Anyway, to put your heart in peace: for ISO 160, go to ISO 200 and then go one third stop down, for ISO 50 - go to ISO 50, this one looks simple to me 🙂
