So, that last firmware update for the Canon EOS 5D Mk II, the one that gave us Christmas in March and brought better video options to everyone on the ‘nice’ list? Well, turns out there might be a fly in the milk. Er, ew.
Quoth Canon:
Recently we have discovered a malfunction that occurs with Firmware Version 2.0.3, in which the manual recording levels for C1/C2/C3 are changed and the 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.
We apologize very sincerely for the inconvenience, but we are going to stop making this firmware available for download. For customers who have already updated to the new firmware, when using the camera with the mode dial set to C1/C2/C3, please either set the sound recording settings to Auto.
We are currently preparing firmware that will correct this malfunction. As soon as those preparations have been completed, we will let you know on this Web site. In the meantime, we apologize for the inconvenience this represents, but please wait until the fixed firmware is ready.
So, well. We’ll keep you posted on when the fixed one makes it’s way out. If you don’t use C1/C2/C3 while setting manual levels ever, well, you probably won’t notice anything wrong and can keep happily shooting away, since nothing seems to be wrong with using it as a camera.
