5.5.1.1 Loading iris tables for Zeiss Ultra Primes,
Variable Primes, High-speed, Standard or
user-defined lenses
(‘TBL LOAD’)
The iris tables for the factory pre-defined lenses
require that a standard gear ring is used on the
lens motor (50 teeth). If other gear rings are used,
the T-stop scale must be completely programmed
from scratch. This also applies if a gear adapter
ring is used with the lens.
The pre-defined iris tables are loaded as follows:
• If ‘IRIS TBL’ flashes on the display when the WRC-1 is
switched on, the MODE button must be pressed once
to enter the ‘TBL LOAD’ mode.
If a lens has already been selected and the T-stops
have been assigned previously, the menu for selecting
the lens can be entered in the WRC rotary switch
position ‘IRIS’ and the COMPENSATION rotary switch
set to ‘OFF’ by pressing the MODE button three times.
• Then press the SEL button. The lens type is shown in
the first line of the display.
