Assigning F-Stops with the ICU-1
The ICU-1 has to be taught where on the iris ring the F-Stops
are. There are two different methods for two different
types of iris scales:
• A linear iris scale is an iris scale where each F-Stop is
exactly the same distance from the next one. Zeiss
Standard Primes, Super Speed Primes and Variable
Primes have a linear iris scale, for example. Assigning
F-Stops for a linear iris scale is a one step procedure.
• A non-linear iris scale is an iris scale where the
distances between the F-Stops differ. The Angenieux
25-250HR has a non-linear iris scale, for example.
Each F-Stop will have to be assigned individually for a
non-linear iris scale.
