Canon EOS 5D Mark III Firmware Version 1.3.3 Coming?

By on

A new firmware version 1.3.3 for the Canon’s full-frame EOS 5D Mark III DSLR camera has been spotted by users on Magic Lantern Forum.

Apparently, some buyers of the new 5D Mark III cameras discovered that their DSLR is running on Firmware Version 1.3.3 even though the Canon USA website shows the latest Firmware as Version 1.2.3.

There is no information or any released new firmware update for the 5D Mk III yet. This could also indicate a possible new firmware upgrade for the Canon EOS 5D Mark III with version 1.3.3. But there is no word on what features or fixes have been made available in Canon’s official firmware version 1.3.3.

Is Firmware Version 1.3.3 for Canon EOS 5D Mark III On The Way?


From ML Forum:

“Few weeks ago I bought a 5D M III. Today I tried to install Magic Latern, but I failed. The firmware version of my camera is 1.3.3, and there was no ML installation file for this version. Then I visited Cannon’s website to download firmware 1.2.3. I tried to install 1.2.3, but my camera said ‘Firmware older than Ver. 1.3.0 is on memory card. Delete old file and update using later version.’. One thing I was surprised about is that there is no firmware 1.3.3 on Cannon’s webpage. It is very strange that my camera is running 1.3.3 firmware.”

The Canon EOS 5D Mark III DSLR camera features a 22.3 Megapixel Full-Frame CMOS sensor, Canon’s new DIGIC 5+ Image Processor and 14-bit A/D conversion.
