Canon this week has released a firmware update to its 12MP digital SLR, the EOS Rebel XSi, which became available in April 2008. The firmware update, version 1.0.9, corrects several issues with the camera. It fixes an issue where the Auto Exposure Bracketing does not operate normally under certain conditions. It also fixes an issue with the Live View exposure simulation warning indicator and an issue with the playback of images after continuous shooting when a printer is attached.
