Panny Lenses with no OIS switch on E-M5

I know this has been discussed a lot....but that was before a lot of people had the E-M5.

For Panasonic lenses such as the 14-42x what was the final conclusion about how to deal with double IS. Simply turn off IS in the camera?

Which lenses have you tried (E-M5 specifically)? How were the results?

Thanks!
