Canon has delayed a new firmware update for the EOS 5D Mark IV that was due in November until February 2018, the company has announced.

Canon posted a notice on its US website it is delaying the release of the firmware update originally scheduled for November 29th, which was due to enhance many of the camera’s features.

Canon cited ‘reasons related to firmware preparation’ for the delay.

Among the new enhancements when the 5D Mark IV firmware update is released are:

  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. Support will be added to fix 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 set (set to Mode 1 or Mode 2 on the menu). For this reason, until the firmware update, when performing viewfinder shooting or LV shooting, please shoot with the Silent LV shooting set to [Disable].
