"This lens model does not have internal image stabilization.
The aperture ring is functional only on Panasonic mFT cameras (not on Olympus OM-D and Pen cameras as their firmware does not suppert this function)"
Has the firmware been updated??? Which v. if so
Posting hear in the hope someone with an answer might look hear in the next few days
