Firmware Version 1.1.4 for the Canon EOS-1D Mark IV camera incorporates the following fixes: 
1. Resolves the following phenomenon: when the camera is not attached to a lens, power consumption may be higher than usual, causing premature battery drain.
2. Resolves a phenomenon in which "Err 02" may be displayed when the shutter is released without a lens attached.

Firmware Version 1.1.4 is for EOS-1D Mark IV cameras with firmware version 1.1.3 or earlier. If your camera's firmware is already Version 1.1.4, it is not necessary to update the firmware. Before updating your camera's firmware, please review the instructions thoroughly.

Preparations for the Firmware Update:

After the downloaded compressed file (.dmg file) is extracted, a firmware folder is created.

*Extracting the downloaded file:
The downloaded folder is automatically extracted, and a firmware folder is created. If the download folder cannot be automatically extracted, double-click the folder.

The extracted folder contains the firmware (file name: 1D400114.FIR / file size: 12,874,604 bytes) and instructions on the firmware update procedures (a PDF file in five languages: Japanese, English, French, Spanish, and Simplified Chinese).

(The following is the history of past firmware updates.)

Q: Are the improvements from previous firmware versions included in Firmware Version 1.1.4?
A: Yes, the following improvements from the previous version are included:

(Previous) Version 1.1.3 improvements:
1. Enables the center AF point to autofocus when the camera is used with the EF 200-400mm f/4L IS USM Extender 1.4x lens and an Extender, whose combined maximum aperture is f/8. 
2. Fixes a phenomenon in which abnormal images may result when continuous shooting mode is enabled and the image size is set to "RAW" or "RAW+JPEG". 

(Previous) Version 1.1.1 improvements:
1. Optimizes the camera’s exposure accuracy when using EF 24mm f/2.8 IS USM and EF 28mm f/2.8 IS USM lenses, which introduced in June, 2012. 
   If these lenses are used with an EOS-1D Mark IV camera that has not been updated with the new firmware, the image may be overexposed depending on the subject and shooting scene. 

(Previous) Version 1.1.0 improvements:
1. Improves writing/reading speeds when using UDMA 7-compatible CF cards.
2. Fixes a phenomenon where the ability to shoot movies may be stopped under the following conditions: 
    * When using high-capacity (32 GB or greater) CF cards with little available space remaining and the user attempts to start shooting movies; or 
    * When the camera’s battery is removed and reinserted into the camera and the user immediately attempts to start shooting movies.
3. Corrects misspellings in the menu screens displayed in Arabic and Portuguese languages (applies to models outside of the Japanese market only).

(Previous) Version 1.0.8 improvements:
1. Fixes a phenomenon in which the set aperture moves unexpectedly when shooting movies in manual exposure mode using some Canon lenses (such as macro lenses). 
    Supplemental Information: 
    This phenomenon involves the aperture of the lens moving unexpectedly when the focusing ring moves (during focusing). Please note that aperture values also change when operating the zoom ring of a zoom lens that has variable maximum aperture values; however, this is a normal operation because the camera controls aperture values properly depending on the focal length (zoom position).
2. Corrects misspellings in the French and Spanish menus for applicable products. 

(Previous) Version 1.0.6 improvements:
1. Enhances the AF tracking performance. 
   AF performance has been enhanced for receding subjects and for subjects that are approaching at a low speed.
