Following on from my previous post, another new firmware update has just been released for the Canon EOS 20D DSLR, along with the following apology from Canon!

“We have discovered that the version 1.0.4 firmware released on October 4 had a bug in the program that handles the update. In cases where the update was performed with a lens attached to the camera, there were situations in which the firmware could not be updated correctly.

In cases where the firmware was not updated correctly, the camera might not power on, the camera might not communicate properly with the lens and flash, or similar malfunctions might occur.

Canon offers its sincerest apologies to customers who have been inconvenienced by this situation.”

Version 1.0.5 is exactly the same as 1.0.4. It just fixes the version 1.0.4 bug where if the update was performed with a lens attached to the camera, there were situations in which the firmware could not be updated correctly. Full details can be found at the following URL:
