New Canon 5D Mark III Kit & Firmware Available

By Anthony Thurston on November 2nd 2013


Canon announced some changes to the 5D Mark III this week in the form of a new kit and a new firmware update. In the new kit the Canon 5D Mark III comes bundled with the Canon 24-70 f/4L IS USM, the old kit came with the 24-105 F4L. The new kit is actually a little more expensive that the old one, coming in at $4,299 (the old one is currently $3,999), and is currently available for pre-order. It is expected to start shipping on November 5th.

Canon 5D Mark III Firmware Update 1.2.3


The other news regarding the 5D Mark III that Canon released  a new firmware update to version 1.2.3. The update fixes a few issues with the camera, but does not add any new functionality or features. This new firmware has been put on newer bodies already, so if you recently purchased a 5D Mark III your body may already have the 1.2.3 update, if so you do not need to worry about updating again. See below for a listing of the 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.

If you want or need to update your 5D Mark III to the new 1.2.3 firmware you can download it directly from Canon via this link.

    Since I’m not really a Canon purist, but do recognize the quality of “L” quality glass, I would really like a 24-70mm f2.8 USD with some sort of IS. Tamron makes such a lens, and the quality is really there. It comes with “VC” which is really good in this lens. (VC is Tamron talk for IS) The lens is a bit large in diameter to accommodate the 2.8 aperture, and heavy to accommodate the new glass elements in the barrel. I’ve found as far as range is concerned, the wider the range distortion becomes higher at the wider end, and low end. So, my suggestion, buy the body, and look at Tamron, Sigma, and Canon for you lens choices.

    Can someone explain to me why you’d want this upgrade? I’m considering making this my Christmas present to myself, but if they are both f4 and both L series lenses…why wouldn’t you want to go up to 105mm? I mean I can always get the firmware update later, no?

      You can get the firmware update at any time, so that part is not relevant as to which kit you get. The 24-70 F4 is a newer lens, I believe it has slightly better optics but other than that you are right the 24-105 gives you more range. If range is important to you then go with that kit.

    Really nothing new here. What about second curtain flash sync? How is it that third party transmitters from China can figure out second curtain sync for the 5D’s but Canon can’t. If the answer is that Canon want to prevent people buying third party speedlights then that’s pathetic. Would they really be willing to sacrifice everyone trying to use their cameras with studio flash in order to peddle a few speedlights? Looking closely at Nikon.

    What about the issue with the previous update that third-party battues were no longer recognized by the camera- prompting a warning message of a lack of communication with the batteries when inserted? Does this new update fix that? or is this canon’s way of saying to buy only their batteries?
