Canon just announced the release of firmware updates for the EOS 5D (and EOS 30D). The update allows the 5D to recognize the full capacity of Compact Flash cards over 8 GB.
I'm still sour at Canon that it hasn't announced a successor to its full frame 5D earlier this year, and hope that the rumors that it will appear next month will prove true. I wonder if the launch of a 5D Mark II (or whatever it'll be called) hasn't been delayed for the Canon engineers to further enhance its specs in order to compete with the new offerings from Nikon, Olympus and Sony?
