Olympus has released firmware version 2.0 yesterday.
You can update your firmware on Olympus cameras and lenses by using the Olympus Digital Camera Updater. The updater also works on Panasonic lenses when connected using an Olympus body.
Version 2.0 updates:
- Small AF target added to the AF target settings.
- ISO LOW (100 equivalent) expanded on the low sensitivity side.
Olympus is also planning on doing a future firmware update to add focus peaking to the OMD EM5!
