Asian sources told me today that the new 1.04 firmware update has been released to Sony related photographers and reviewers. They are now currently testing it to check for issues. The firmware is not going to be published this week. Sorry, there has been a communication mistake between the sources. They first told me that Sony would release the firmware this week but only now they understood that it is just an “internal” release.
Please understand that this is a rumors website, it’s hard to get every time 100% reliable and super correct info. Anyway, the update should be very soon available for us normal customers too!
