2. Adds a function for manually adjusting the sound recording level (64 levels). 3. Adds a histogram display (brightness or RGB) for shooting movies in manual exposure. 4. Adds shutter-priority AE mode (Tv) and aperture-priority AE (Av) mode to the exposure modes for shooting movies. 5. Changes the audio sampling frequency from 44.1 KHz to 48 KHz. 6. Fixes a phenomenon where communication between the camera and the attached lens is sometimes interrupted after manual sensor cleaning. (This phenomenon only affects units with Firmware Version 1.2.4.)
Firmware Version 2.0.3 is for cameras with firmware up to version 1.2.4. If the camera's firmware is already version 2.0.3, it is not necessary to update the firmware.
Movies captured using EOS 5D Mark II cameras with Firmware Version 1.1.0 to 1.2.4 can be played back on cameras updated with Firmware Version 2.0.3. However, if you try to play back movies captured with a camera with the new firmare on a camera with a previous firmare version, a message, Cannot play back image, appears on the camera's LCD monitor.
It is recommended that you use the latest Canon applications*1 to edit movies captured with EOS 5D Mark II cameras that have the latest firmare because some previous versions do not support movie-editing functions and the frame rates that are added or changed by the latest firmware. You can download the latest Canon applications from our Web site. *1 ZoomBrowser EX Version 6.5.0 or later (compatible operating systems : Windows XP/Vista/7) ImageBrowser Version 6.5.0 or later (compatible operating systems : Mac OS X v10.4/10.5/10.6)
