I'm owning a G11... (FW:1J)
unfortunately, if I deactivate the af assist beam (the white LED) in the canon menu, it will only affect the no-flash-mode. If I want to use the (internal) flash, the assist beam comes up.
This is annoying, if I want to take a candid shot of children and pets.
Well... I could use black electrical tape to shut down the lampf... but it should easily be possible, to absolutely deactivate this LED feature via CHDK.
Do other canon cameras with assist LED behave the same?
