Canon EOS 5D Mark II 2.0.3 Firmware Update Yanked

Canon released the long awaited 2.0.3 firmware update for it’s Canon EOS 5D Mark II a couple of days ago, but we hear the firmware has now been yanked off the Canon site due to some technical difficulties with the Audio breaking down.

The audio issue occurs when manual recording is set on C1/C2/C3 and the camera is either switched off manually or automatically. Canon recommend for now that users with 2.0.3 on their EOS 5D switch to automatic mode while the bug is ironed out.

It isn’t know at the moment how quick Canon will fix the error but for now the old 2.0.3 has been removed from the site till a new firmware update is ready. It could be hours, days or perhaps weeks depending on how quick and easy the fix for the digital SLR camera is.

If you own a Canon EOS 5D Mark II then Canon recommend you register it with the company so you receive an update via email.

Important Update Information for
Firmware Update Version 2.0.3
We recently discovered a malfunction that occurs with Firmware Version 2.0.3, which the manual recording levels for C1/C2/C3 are changed and the EOS 5D Mark II digital SLR camera becomes unable to record audio if the power is turned off (or if Auto power off takes effect) after registering “Sound Recording: Manual” in the camera user settings. For customers who have already downloaded and updated to Firmware Update Version 2.0.3, when using the camera with the mode dial set to C1/C2/C3, please set the Sound Recording settings to Auto to record with audio.

We are currently preparing a new firmware that will correct this malfunction and have temporarily disabled the ability to download the current firmware until the issue can be resolved. We will re-enable the download link on our web site and notify you via email when it becomes available. If you have not registered your EOS 5D Mark II, please register so we will be able to notify you.

Canon always strives to provide the highest quality products to our customers. We sincerely apologize for any inconvenience this may have caused. We appreciate your kind patronage and support.
