From Rob Galbraith:
“Some are being told that the new fix is comprised of both a hardware change and new firmware, others are being told that it's not known yet at Canon USA whether the fix is comprised of hardware, firmware or both. This apparent discrepancy in what reps are saying is probably indicative of how new this information is to them, and how little information they themselves have been given so far by higher ups in the Canon organization. Canon USA reps aren't sharing any other specifics about the nature of the new fix.”
The fun of owning a 1d3.
