Well, at least they fix what they just had fixed pretty soon enough ...Firmware Update for OLYMPUS DIGITAL CAMERA
[ E-M1 ]
[ Caution ]
When updating the firmware from Version 1.0/1.1/1.3/1.4 to Version 2.2, the camera settings other than the AF focus adjustments are reset.
When updating the firmware from 2.0 / 2.1, the camera settings are maintained.
The issue in firmware version 2.0 and 2.1 where bright points appear in some images has been resolved.
Precision of AF when M.ZUIKO DIGITAL ED 40-150mm F2.8 PRO lens is mounted has been improved.
Now where is that darn lens ...
All the best.
