Since 14-42mm doesn't have OIS on/off switch on the lens, can G1 activate IS function within the camera body?
Very helpful tip, thanks.IIRC, there was a firmware update for the G1 back around May which added an additional menu option for enable/disable IS on the 14-42mm lens.
Seems to be confirmed by Panasonic Japan. It's footnote item 11 (*11) which states the 14-42mm is supported on G1 firmware version 1.5 or later.
