Canon just released Canon EOS 5D Mark II (reviews) firmware update 2.0.8. You can find the download on this Canon Japan page. None of these appear to be any major improvements, only bug fixes, but if you've been suffering from one of these bugs, you'll be happy. And, as always, you can find all the firmware info on the planet5D wiki – specifically on this Canon EOS 5D Mark II firmware page.
This firmware update (Version 2.0.8) incorporates the following changes and fixes.
- Fixes a phenomenon in which movies are not taken at the shooting mode registered in the user's settings if a shooting mode Aperture priority (or Shutter priority) is registered in any of the camera's user settings (C1, C2, C3) and the user attempts to shoot a movie.
- Fixes a phenomenon in which the shutter will not release when pressing the shutter button when the auto power off function is set to “on”.
- Fixes a phenomenon in which overexposure occurs when shooting a Live View shooting simulation with the ISO speed set to L.
- Fixes a phenomenon 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.
- Fixes a phenomenon in which the Macro Ring Lite (MR-14EX, MT-24EX) and slave flash do not sync while shooting wirelessly.
And, if you've never done a firmware upgrade, here's a how to video that was done for an earlier release. No difference with this version.
