New Canon EOS-1D X Mark III firmware coming in April to address issue

My readers know I have recently returned from Hokkaido, Japan to put the EOS-1D X Mark III camera through a real world test. My first review is here. There will be addendum as I go on more wildlife photography tours, further testing the new camera.

I have experienced (once) a seize up with the EOS-1D X Mark II and Mark III bodies when firing in the maximum burst mode, in severely cold weather. A quick pull out and reinsertion of the battery cleared the problem immediately.

In addition, there is a phenomenon, which I have not experienced, as described below :


When the camera is used with the electronic level set to “Show” in the viewfinder display, in rare cases, the camera may not perform normally when operating the AF-ON button or shutter button.

Affected Product:

EOS-1D X Mark III (Firmware version 1.0.0)


Use the “Hide” setting for the electronic level in the viewfinder display.

Setting procedure: Menu / Set-up 2 tab / Viewfinder display / Electronic level* [Hide]
*Default setting: [Hide]


In early-April 2020, Canon plans to release a firmware update to address the phenomenon listed above.
