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.
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.
