firmware

The release that Canon just did the other day has been pulled and replaced. Here’s the story:

We apologize sincerely for the inconvenience caused to our customers by suspending the availability of the Version 2.0.3 firmware.

We are now introducing the Version 2.0.4 firmware. This firmware corrects the malfunction that occurred in the previous Version 2.0.3 firmware, in which the manual recording level changed and made recording impossible.

Customers who have the Version 2.0.3 firmware on their cameras should update the firmware to Version 2.0.4.
EOS 5D Mark II Firmware Update Version 2.0.4
Firmware changes

In the Version 2.0.4 firmware, the following phenomena that occurred with the Version 2.0.3 firmware (which was to enhance the movie functions) have been corrected.

* There was a phenomenon in which the manual recording settings made in C1/C2/C3 were changed and sound could not be recorded if manual sound recording was used in the C1/C2/C3 settings and the camera was subsequently turned off (or if Auto Power Off was activated). This does not occur in modes other than C1/C2/C3.

The Version 2.0.4 firmware includes the movie function enhancements listed in items 1 through 5 below, and also incorporates the correction listed in item 6.

1. Adds or changes the following movie frame rates.

NTSC:
* 1920×1080 : 30 fps (changed - actual 29.97 fps)
* 1920×1080 : 24 fps (added - actual 23.976 fps)
* 640×480 : 30 fps (changed - actual 29.97 fps)
PAL:
* 1920×1080 : 25 fps (added - actual 25.0 fps)
* 1920×1080 : 24 fps (added - actual 23.976 fps)
* 640×480 : 25 fps (added - actual 25.0 fps)

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.)

Caution:

* Firmware Version 2.0.4 is for cameras with firmware up to version 2.0.3. If the camera’s firmware is already version 2.0.4, 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 2.0.4. 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)
* In addition to the enhancements to the movie function, the accompanying instruction manual has also been revised. Users are asked to download both the latest firmware and the latest instruction manual. You can proceed to download the instruction manual by clicking the [I Agree] button from the bottom of this page.
