Canon has released a firmware update for the EOS 40D Digital SLR.  This update fixes an incorrect low battery warning when using the EF 85mm F1.2L II USM Lens; fixes an incorrect “Err 06” error message that may appear depending on the timing of when the camera is switched “On,” corrects an issue where incorrect colors would be printed when using the direct print feature to print RAW images captured using specific Picture Styles;  enables an external flash connected to the camera’s synchro terminal to fire even when the camera’s built-in flash is popped up; modifies the level of subject brightness that causes the AF-assist beam to fire when using an external Speedlite.
