I just came across this video where the author is faced with a dilemma to manipulate the image or not. Have a look - https://www.youtube.com/watch?v=rWeHDWtMf2o
Thanks for the replies! The IBIS did cross my mind, and it engaging and disengaging when on/off would make sense. Because once turned on, it feels rock solid. There are no other issues (controls, image quality etc), so I am not worried and look forward to snapping away 🙂.
