Canon has released firmware version 1.2.3 for the EOS 5D Mark III, which fixes four bugs (including one in which the flash may not fire when the shutter is pressed) and adds the ability to adjust LCD brightness when an HDMI cable is connected.


Canon has released a firmware update for the EOS 5D Mark III.

Firmware Version 1.2.3 incorporates the following improvements and fixes.

  • Fixes a phenomenon in which the flash may not fire depending on the timing of when the shutter button is pressed.
  • Fixes a phenomenon in which the AF microadjustment value may change.*
  • Fixes a phenomenon in which the LCD monitor may show a line of false color along boundaries of high contrast.
  • Fixes a phenomenon in which the histogram of a LiveView image is incorrectly displayed when an HDMI cable is connected.
  • Enables the brightness of the camera's LCD monitor to be adjusted even when an HDMI cable is connected.

* The phenomenon listed in 2 was addressed with Firmware Version 1.2.1, and has been further improved with Firmware Version 1.2.3.

Firmware Version 1.2.3 is for cameras with firmware up to Version 1.2.1. If the camera's firmware is already Version 1.2.3, it is not necessary to update the firmware.

The new Firmware Version 1.2.3 can be downloaded by clicking here.

The new firmware has a BUG.

A BIG BUG.

It doesn't recognize certain batteries, even the genuine OEM ones from Canon, which the previous version RECOGNIZED!

This occurs at random on many users.

Canon: This is Firmware Failure at the highest degree.

Please put a WARNING out to your users.

NOW.

No problem running the update. I'd had some issues with the camera applying random AFMA to different lenses, so hopefully things stay where they should from now on.

I did it yesterday, spent about 30 minutes looking for problems afterwards, didn't find any. Do it with the usual precautions, including keeping any dogs, cats, and children away from the buttons.

Well, software problems are "issues" so why not?

Phenomenon is the closest English equivalent of the Japanese word "gensho". This might be too literal a translation for English consumption. The original Japanese word conveys just the right amount of responsibility on the part of the manufacturer without them loosing too much face.

Anything not in the specification is a bug... so these aren't phenomena, they're bugs..!

For your education greyhorse , Phenomenon is the Greek word "φαινόμενο" , one of the thousands Greek words used by english language.

I have two bodies running 1.2.1 and am experiencing no issues that I can tell. I've been busy shooting weddings under all weather and lighting conditions with various lenses and have experienced no glitches. While I am not normally one to shun a firmware update, I usually like to wait a little while in case a glitch related to the update surfaces. I can't afford to brick a body when I have people depending on me to shoot. No offense to Canon. I treat all updates with equal caution be it firmware or software (unless I'm experiencing real and serious issues needing an update).

Treat is like flu shot, most likely you can get sick by getting it. :)

update worthwhile as I found my camera had changed the micro adjustment by itself to +8 ! I had previously only had 1.2.1, so if you are the same - worth checking the your micro adjustment setting if you want sharp images!
