Canon EOS 7D Firmware Update Version 1.2.3 out today

by planetmitch4 Comments

Canon has surprised us with a release of updated firmware for the Canon EOS 7D (reviews) – this one is version 1.2.3 and it is just a couple of bug fixes – no new features were added. Thanks to the 5D Mark II Team for alerting us.

Download the update from this Canon Japan site.

Many will be disappointed in this update as they've been hoping that Canon would add the same manual audio controls that were added to the Canon EOS 5D Mark II (reviews) firmware earlier this year.

Firmware changes

Firmware version 1.2.3 incorporates the following fixes.

  • Fixes a phenomenon in which the settings of the Speedlite Transmitter ST-E2 revert to the default settings when both the camera and the ST-E2 are set to auto power off.
  • Fixes a phenomenon in which the Macro Ring Lite (MR-14EX, MT24-EX) and slave flashes do not sync while shooting wirelessly.

Firmware version 1.2.3 is for cameras with firmware up to Version 1.2.2. If the camera's firmware is already Version 1.2.3, it is not necessary to update the firmware.

Note that cameras with the version 1.2.3 firmware (and also versions 1.2.0 through 1.2.2) cannot be downgraded to a previous firmware version (such as version 1.1.0 or earlier).

Are the previous versions of firmware included in version 1.2.3? Yes, the following improvements from the previous version are included.


And, if you've never done a firmware upgrade, here's a how to video that was done for an earlier release. No difference with this version.

  1. Again canon are not listening to their customers who own 7Ds. We want manual audio! How much clearer do we have to make it?

  2. Another Firmware Update that only includes Fixes

    It is GREAT that Canon fixes the reported bugs, and also the ones their technicias find, of course.

    BUT Canon should also fix the INCONSISTENCY and INCOHERENCE between CURRENT HDSLRs’ features.

    It’s not acceptable to find cheap cameras with many useful, and even basic, features that are not implemented on much more expensive models.

    These are just few examples:

    * “Clean” HDMI / AV output (function to enable/disable the white focus square in Live View mode. So easy to do, NOT implemented in any DSLR yet…)
    * Auto ISO Limiters, essential for M mode (in normal & Live View mode) (* Only on 60D & T2i)
    * Manual Audio gain control (* Only on 5D Mark II & 60D)
    * More frames available on Bracketing mode (for HDR photography) (* only in 1D Mark IV & somewhat present in 60D)
    * Capability to “Edit” movie/video clip in camera (* Only on 7D, 60D, T2i but NOT in 5D Mark II)
    * Movie “Crop” mode (* Only on 60D & T2i)
    * And OBVIOUSLY the 50/60p mode (implemented in ALL cameras, except 5D Mark II…).

    Note that all these features do NOT require any hardware change. They can be implemented via Firmware Update (software), so there is no real hardware limitation.

    We have never seen so much incoherence between expensive and cheap cameras before.

    In respect and consideration to their customers, it would be very good for Canon to “match” their features the best they can.

    Finally, this is a List of Fixes & Improvements we have been telling since almost 1 year ago:

    It’s interesting to note that some of those ideas were already posted before, and implemented by Canon in the latest models like T2i and 60D, but not in higher level cameras… Even when they can.


  3. Yes Manual Audio Gain Control Please for the 7D. I have two of these and I shoot weddings. During the reception the audio is distorted and I’d like the ability to try to prevent that or reduce the amount of it!

    I would like other features that “5d mark2 team” to be implemented also. But Manual Audio Gain is the most glaring one.

    I had a T2i for a few months and I was puzzled why it did not have manual white balance in kelvin and it did not allow for the intermediate iso during video recording (iso 1250 is what I need often)
