1D MarkIV firmware update to version 1.1.1

It's time to grab the 1D MarkIV and make another firmware update.

This time Canon just addressed a couple of things that has to do with the new lenses that will be released sometime in June 2012. During this updates I just wish Canon would give us some more feedback on what was really corrected and not just a few hints on what they thing is major for the update firmware.

Canon how about give us the shutter release counter permanently visible so we can manage our trips to Canon repair center like we do with our cars?

Here is what's corrected with this 1.1.1 firmware update:


Firmware Version 1.1.1 incorporates the following change.
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 are scheduled for release 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.

Firmware Version 1.1.1 is for cameras with Firmware up to Version 1.1.0. If the camera's firmware is already Version 1.1.1, it is not necessary to update the firmware.

Cameras with Firmware Version 1.1.1 cannot be restored to a previous Firmware Version (such as Version 1.1.0 or earlier).

(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.
