Love this forum - thanks everyone for chipping in with helpful comments (even if some not what I want to hear! )

Chris: This is interesting but I think there is a distinct difference between what you are decribing and what I am am experiencing. In my case as I mentioned above the offending sound happens sporadically even when the lens cannot be focusing (e.g. when in single-AF without the shutter button depressed and also in MF). And it's intermittent - sometimes I can hear it at the same time as I can here the "wooosh" (fan type noise) for the IBIS, but other times it is there separately even when the IS isn't running.
