It looks like the coast is clear for owners of the Canon EOS 5D Mark II to upgrade their firmware. The newly released 2.0.4 firmware includes all of the improvements we saw in version 2.0.3 that was released last week, but without the side effect of rendering the camera unable to record audio in certain circumstances. The new update also fixes the malfunction for those that had already upgraded to version 2.0.3 before it was pulled, so Canon is encouraging all users to update to version 2.0.4.
The 2.0.4 version firmware is available now from Canon’s website.
