New Firmware for the EOS 5D Mark IV Coming on March 2018

By on

Canon plans to release a firmware update for the popular EOS 5D Mark IV DSLR camera on March 2018.

The new firmware will apparently fix a few bugs and adds support for new lenses and features. Canon 5D Mark IV features a 30.4 megapixel CMOS sensor with Dual Pixel AF. The sensor allows for fast phase-detection autofocus in video and continuous focus for stills shooting in live view. See Canon EOS 5D Mark IV additional coverage with sensor test results.

Future Firmware Plan for the EOS 5D Mark IV can be found below.

Upadate:
On February 6, 2018 we revised the availability of future Firmware from late February to a late March 2018 release.

The original advisory content is provided below.

Release of the new EOS 5D Mark IV Firmware which was originally scheduled to be available on November 29, 2017, at the same time as the firmware updates for six other models (EOS-1D X Mark II: Ver. 1.1.4; EOS-1D X: Ver.2.1.0; EOS 5D Mark III: Ver.1.3.5; EOS 5DS: Ver.1.1.2; EOS 5DS R: Ver.1.1.2; EOS 6D Ver. 1.1.8), has been postponed until late February 2018. We would like to offer our sincere apologies to users of this product who have been inconvenienced.

The new EOS 5D Mark IV Firmware will incorporate the following fixes and enhancements:

  1. Support will be added for chromatic aberration correction, peripheral illumination correction, distortion correction, and Digital Lens Optimizer when using Digital Photo Professional to process RAW images captured with the following TS-E lenses: TS-E 17mm f/4L, TS-E 24mm f/3.5L II, TS-E 50mm f/2.8L MACRO, TS-E 90mm f/2.8L MACRO, or TS-E 135mm f/4L MACRO.
  2. Fixes a phenomenon* in which standard exposure may not be obtained, or an irregular exposure may result, when Silent LV (Live View) shooting with the following TS-E lenses: TS-E 50mm f/2.8L MACRO, TS-E 90mm f/2.8L MACRO, or TS-E 135mm f/4L MACRO.
  3. Support for Exif 2.31 will be added.*This phenomenon occurs when tilt or shift is applied on a TS-E lens (TS-E 50mm f/2.8L MACRO, TS-E 90mm f/2.8L MACRO, or TS-E 135mm f/4L MACRO) during LV shooting when Silent LV shooting is selected (set to Mode 1 or Mode 2 on the menu). Until the new firmware is available, when performing viewfinder shooting or LV shooting, please shoot with the Silent LV shooting set to [Disable].
