Originally posted by jolepp I suppose it is not especially clever using the SD busy light this way, as the message normally is: "when I'm lit do *not* remove the card or physically (*) cut power".
(*) under normal circumstances I assume the power switch is a soft one which means it can be actually used to flush buffers to card :-)
I dunno, it seems to me that reading the instructions that came packed with the firmware update is clear enough.
"8. When update is completed, the "COMPLETE" will be displayed at the left
bottom of the LCD monitor, then turn the camera off."
A brass band leaping out of the camera and playing a rousing Sousa march would be over the top, and people would still question whether the update had completed.
