FYI, here what this firmware update does/changes:
Version 2.11 for Sinar Hy6
• Supports Sinar Hy6 65 and Sinarback eSprit 65 LV
• In order to operate with a Sinar Hy6 with firmware
2.11, a Sinarback eMotion must be equipped with
firmware version 5.08 or higher.
• The Exposure Bracketing now is also supported
when using the SCA flash interface
• Long time exposures are no longer aborted by
pressing the exposure release button a second time.
Now, to abort long time exposures the camera has
to be switched off.
• The "Flash ready" information on the focusing
screen display has changed.
Best regards,
Thierry
