Firmware v1.1.0 for Canon EOS-1D Mark IV now available
Tuesday, May 31, 2011 | by Rob Galbraith
Firmware v1.1.0 for the Canon EOS-1D Mark IV improves read/write speeds with certain CompactFlash cards, corrects an instance in which video capture may stop prematurely and fixes errors in the Arabic and Portuguese menu screens.
The full list of stated changes is below.
Firmware Version 1.1.0 incorporates the following improvements and fixes:
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 the Japanese market only).
The update is available from the EOS-1D Mark IV's Drivers & Software page on the Canon USA website. Proceed with caution when installing the new firmware: we've received a report of v1.1.0 rendering the camera unusable, though it did install just fine on one body here.
