My 5D has firmware version 1.0.3, and that's the version that Canon currently has on their website as being the current version.
But on other forums and places on the Internet there are people reporting that they have firmware version 1.0.4 or even 1.0.5 on their brand new 5D. Here for example
is someone who says he has version 1.0.5.
So it looks like there's going to be an update soon. Why would Canon be introducing it so quietly like this - why don't they make 1.0.5 available on their website immediately? And I wonder what the differences are going to be.
