I was thinking today about IS, and realized that I dont know that much about how it works.
After doing a little research into it I now feel I have a better understanding.
The Canon system uses electromagnets to move a floating lens element that counters camera shake. This means obviously that moving parts are involved.
Attached is a diagram from the Lens Work III book showing the system.

I am assuming that because there are moving parts involved, it would be more likely that the lens could be damaged from impacts.
Can anyone confirm this, or add any additional information?
Should we be extra careful with IS lenses, or are they as durable as non-IS lenses?
