When it applies
- RF-S18-150 and RF-S18-45 use camera IS mode On for combined IS.
- RF50 F1.8 STM uses camera IS mode On for body IS.
- RF24-105 F4L and RF100-400 use lens IS ON; the camera IS-mode toggle is hidden.
- RF24-105 F4L combined-IS feature requires lens firmware 2.0.6 or later.
Where it stops
- Effectiveness is not guaranteed; image stabilization does not establish subject-motion freezing.
- No camera firmware number is assigned when the source specifies none.
