The info manual says to turn off the IS when not in use, can it drain the batt with the camera off? Can it cause any probs if left on?
thanks, Pete

I don't want it running if it's not needed. Not for battery concerns, but for the lifetime of the IS "engine". defordphoto | Celebrating the art of photography®

When looking through the viewfinder the image does not stablilize until you press the shutter button. It also continues to run for a sec or two after you release the shutter. Which is why you should give the IS a sec to spool up before you snap the shutter. I could be wrong but that is the way it seems to work for me. My Pictures

joeseph "smells like turd" More info | Nov 30, 2004 21:49 | #7 May or may not be related, but turned my D60 on after a couple of idle days with the new 100-400 on it (switched off) = absolute dead flat batt. some fairly old canon camera stuff, canon lenses, Manfrotto "thingy", and an M5, also an M6 that has had a 720nm filter bolted onto the sensor:
