    On the OM-D. When the shutter is half pressed, does this initiate some type of little motor. I here it focus but the little "motor" noise does not stop as long as I hold down the shutter.

    Is this normal behavior?

    Thanks for any help

    It's normal behavior -- that's the sound of the active IBIS (in body image stabilization) mechanism.

    it used to be on all the time when powered up. they made a firmware update that only turned on the IBIS cooling fan when the shutter release was depressed. I wish they made it configurable. I could really use the IBIS on all the time with legacy glass.

    The presence of a cooling fan was the subject of some debate when the EM5 originally came out, but there is no fan.

    Also, IBIS was never on all the time; you always had to at least depress the shutter halfway to get it to activate, via the following menu setting:

    Gear C -> Half Way Rls with IS, select "On"

    The only change in the firmware update you refer to was that the noise became less apparent when IBIS was not activated (i.e. before depressing the shutter).

    That' the sound of a little miracle. I crack a little smile every time I hear it. Enjoy your IBIS>

    It's dependent in the setting in Gears C, Half Way Rls with IS...that will determine if you have IS on when you half-press, or only when you take the picture.
