Canon Posts New Firmware for G1 and Pro90

I just received an email from Chuck Westfall at Canon USA informing me that they had just posted firmware updates for the PowerShot G1 and the PowerShot Pro90 IS cameras.

Improvements over previous firmware:

PowerShot Pro90 IS and G1

• It is no longer necessary to reset the date at the end of the month.
• Correction of an underexposure problem that occurred in low light conditions when an EX-series Speedlite (220EX / 380EX / 420EX / 550EX) was mounted on the camera but turned off.
• Speedlites 160E and 200E will now flash when mounted on the PowerShot G1. But, as they are not EX-series Speedlites, they will fire at full strength. (Automatic flash exposure with the PowerShot G1 is only possible using the built-in flash or an EX-series Speedlite.)
• Correction of problem in which initial shutter 'click' sound would occasionally not emit upon exposure after turning the power on.
• Eliminates the occasional occurrence of unusual brightness or darkness in the LCD panel display when the shutter button is pressed halfway in the Tv mode.
