Does the new Olympus PEN E-P5 firmware reduce image shake?

Message from Olympus Japan:

Thank you for your e-mail regarding our product.

We apologize for any inconvenience for
the blurred/shaken images at certain shutter speeds.

As you know “anti-shock 0sec” for E-M1 has been updated and we
believe that this update can help to resolve the shutter shock issue you mentioned.

At this point, there are no firmware updates for E-P5 to resolve the
shutter shock issue.

However, we are planning to update the firmware for E-P5 similar
to “anti-shock 0sec” as well. Please wait for the update to be
released for a while.

We are sorry but we are not able to tell you when the update will be
released at this point.
Please check Olympus homepage from time to time for the latest
information of firmware.

We appreciated your kind cooperation and understanding,
looking forward to see your satisfaction on our service and product.

Best regards,

C.Nishino
