e-p1 IS, when does it kick in?

    So I've only had my e-p1 for about a week.

    The first time I heard the IS turn on I was left wondering "what is that horrible grinding noise?" It mainly confused me because I didn't hear it all the time.

    After some searching, I believe I read that IS does not turn on if the shutter speed is above 2 seconds. (and it seems audibly true on my e-p1).

    After some playing around... I'm under the impression that there's a minimum shutter speed at which the IS also doesn't turn on - but I'm not quite sure what it is...

    does anyone know what the shutter speed range for IS to turn on is?

    Depends on the focal length of the lens fitted. For non 4/3rds lenses, you can enter the focal length.

    I must admit, I can never hear it. Certainly not over things like the auto focus motor, SSWF and shutter - all of which make pretty horrible noises.

    IS only turns on when the photo is taken, it's not always on - unless there's a setting I haven't found.

    Set your shutter to something like 1.5 seconds. You'll hear the focus, shutter, then after the shutter opens you'll hear a rumble, which stops when you hear the shutter close.

    OK, I did that and yeah there is a rumble. I thought that was Olympus's attempt at the old nastolga bit of the noise of an old clockwork bulb timer or self-timer.

    I never hand hold at those sorts of shutter speeds and turn IS off when shooting on a tripod so it is no wonder I haven't heard it. You don't notice the IS over the noise of the shutter at normal hand held speeds of around 1/8and faster.
