Stop the presses… just received from Canon USA via email:
Canon U.S.A., Inc., will be issuing a greatly anticipated firmware update for the EOS 5D Mark II Digital SLR Camera. This new firmware will accommodate a great number of user requests for manual exposure control in the EOS 5D Mark II video mode. Manual exposure control while shooting video on the EOS 5D Mark II is expected to make a big impact with cinematographers and videographers using the 5D Mark II for high-end HD video production. While being announced today, this firmware will not be available for download until early June 2009.
