I sent my camera in for warranty repair (focusing issues as well as the random mirror-up in the middle of a shoot annoyance).
They stated they
Replaced "printed circuit boards and/or image sensor."
Adjusted and calibrated all circuits "for proper function."
Replaced or adjusted autofocus circuit "including focus motor and encoder, CCD focus device and laser alignment of all mirrors"
I just checked the info:
Pre-repair:
Manuf. Date - Dec 09 2006
Rev 1.1
Firmware 1.2
Post-repair:
Manuf Date - Mar 28 2008
Rev 8.1
Firmware 1.0 (reflashed to 1.3 as soon as I noticed)
I think 8.x comes when they replace the guts...
Question is - What does this mean? Will my camera have GPS and WiFi now? Will it know when it's Miller Time?
