I-TTL Ratio Mode
This mode allows you to set power ratios between
groups A and B. Group C works independently and
offers TTL, manual, or off modes. For example, if you
set a ratio of 1:2 between groups A and B, group B will
fire with two times more power than group A.
1. Press the Mode [ ] button to switch to I-TTL mode.
2. Press the Group [ ] button to highlight and enter group selection, and use the adjustment dial to select
groups A:B or C.
3. When A:B is selected, press the Set [ ] button once to select the group flash ratios. Use the adjustment
dial to select a ratio from 8:1 to 1:8.
4. Press the Set [ ] button again to adjust the zoom focus parameter. Use the adjustment dial to set the
zoom focus.
