Official Firmware Updates[edit | edit source]
There is an official firmware update by canon, that isnt really official, but at least its by canon...
It adresses problems with Hi Res Video mode Manual Focus. It updates the camera to 1.00i.
PLEASE READ THIS CAREFULLY !
- See here for further details, warnings, and a download link
Note about the different Firmwares[edit | edit source]
Cameras with the 1.00f firmware can/must use the CHDK version for 1.00g - the autobuild already just copies this, so when you have a 1.00f cam you will find YOUR version in the autobuild. Development is happening in the 1.00g tree, then compiled and just renamed for the 1.00f people.
