Canon EOS 5D Mark III Firmware Version 1.2.3
Canon USA just released Firmware Version 1.2.3 update for the Canon EOS 5D Mark III DSLR.

Firmware Version 1.2.3 incorporates the following improvements and fixes.
  1. Fixes a phenomenon in which the flash may not fire depending on the timing of when the shutter button is pressed.
  2. Fixes a phenomenon in which the AF microadjustment value may change.*
  3. Fixes a phenomenon in which the LCD monitor may show a line of false color along boundaries of high contrast.
  4. Fixes a phenomenon in which the histogram of a LiveView image is incorrectly displayed when an HDMI cable is connected.
  5. 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.
When updating the firmware of your camera, please first review the instructions thoroughly before you download the firmware.

I have been having an issue with #1 for a while and it has been driving me CRAZY. Plan was to send it in after the season dies down I hope to god this is all it was it will save me the trouble of sending it in and them telling me they can't recreate the issue.

Damn while bug fixes are always welcome, where's the equivalent FW announcement like for the 1D X/C?

My heart skipped a beat for a few seconds while this page loaded

me too, although it was a silly thought, I mean they would never pop out the 5D3 stuff instantly after having told the 1DX users they must wait a few months

anyway nothing here for me to ever give up the ability to use ML, no way, no how, i'll live with the bugs

Great timing! No. 1 plagued me while I was shooting this evening. I had three black frames out of twenty.

I received my 5D mark III on 10/27/13 (Shipped 10/24). I just checked and it shows that Version 1.2.3 is installed.

Now I get a "Battery communication error" message with my 3rd party batteries that I didn't get before.

That's a feature as far as Canon is concerned.

It certainly appears to be 'the way of things' with new EOS firmware updates. Canon really don't want you to use non-OEM batteries.

As a 6D owner now I've rather go used to this, but annoying nonetheless

FINALLY!

that has been driving me crazy; can't tell you how many reception/party shots I've missed because the **$#^$&*ing flash didn't fire. I sent one of my 5d3's in to CPS twice to get it checked out, and they said they hadn't heard about this issue.

Just downloaded this to my laptop. Do I unzip before copying to the camera or will the camera do that?
Thanks and best wishes.

I wish they'd feature a 50% discount on LP-E6's for a month! They are a complete rip-off for what they are - lithium cells and a chip in cheap plastic housing.

My body has the original firmware from 2012. Is it worth updating at this time?
