Canon has released firmware update version 2.0.8 for their 5D Mk2 SLR. The update addresses several problems including: Movies are not taken at the shooting mode registered in the user’s settings if Aperture or Shutter priority is set in any of the camera’s user settings (C1, C2, C3); if the user attempts to shoot a movie, the shutter will not release when pressing the shutter button when the auto power off function is on. In addition, it fixes the issues of overexposure when shooting a Live View shooting simulation with the ISO speed set to L and also the problem in which the settings of the Speedlite transmitter ST-E2 revert to the default settings when both the camera and the ST-E2 are set to auto power off. Lastly it repairs a phenomenon in which the Macro Ring Lite (MR-14EX, MT-24EX) and slave flash do not sync while shooting wirelessly.
It is available for download from Canon.
