Firmware Update

Fixes a phenomenon in which the image files cannot be transferred using the FTP protocol via USB cable after the EOS 7D camera has established a wireless connection to the Wireless File Transmitter WFT-E5 (A/B/C/D).

Fixes a phenomenon in which the camera stops working when the auto power off setting takes effect.
Fixes a phenomenon in which the maximum number of images that can be captured in a burst displayed in the viewfinder may be less than what can actually be captured.
Corrects some errors in the message displayed on the LCD screen when saving RAW images developed in the camera.

Improves the maximum burst in continuous shooting.
JPEG Large/Fine: About 94(126) bursts *1 -> About 110 (130) bursts *2
RAW: About 15 (15) bursts *1 -> About 23 (25) bursts *2
RAW+JPEG Large/Fine: About 6 (6) bursts *1 -> About 17 (17) bursts *2
*1 The figures are based on Canon's testing standards (ISO 100 and Standard Picture Style) using a 4 GB card. The figures in parentheses indicate the number of shots that can be taken with an Ultra DMA (UDMA) 4-GB card, based on Canon's testing standards.
*2 The figures are based on Canon's testing standards (ISO 100 and Standard Picture Style) using an 8 GB card. The figures in parentheses indicate the number of shots that can be taken with an Ultra DMA (UDMA) 128-GB card, based on Canon's testing standards.
Supports a new accessory, GPS Receiver GP-E2.
Adds an ISO Auto maximum setting.
Adds an in-camera RAW processing function.
Adds a Quick Control function during image playback.
Adds a rating function.
Adds a JPEG resize function.
Adds an auto recording level manual adjustment function.
Adds a function to freely set text for file names.
Adds a function to make time zone settings.
Increases the screen scrolling speed when magnifying images.
Fixes a phenomenon where a slow shutter speed may result when an external flash is used to fire intermittent, consecutive flashes.
Corrects the color space information in the Exif file for movies.

Fixed a rare phenomenon in which there were rare cases where movie files taken could not be opened when repeatedly shooting movies with specific CF cards.
Fixed a rare phenomenon in which there were cases where "Err 02" appeared when repeatedly shooting still images with specific CF cards.
Fixed a phenomenon that occurred when using high-capacity (32 GB or greater) CF cards: If either a CF card with only a little available space remaining or the battery was removed and then reinserted into the camera, and then the user attempted to start shooting movies immediately, shooting would stop.
Improved the writing/reading speeds when using UDMA 7-compatible CF cards.
Fixed a phenomenon that occurred when custom function C.Fn 4-1 was set to assign IS start to the AF stop button on the lens: When used with lenses that do not have an AF stop button, the IS function would not work.
Corrected some mistakes in the menu screens displayed in Arabic and Portuguese.

Fixes a phenomenon in which the settings of the Speedlite Transmitter ST-E2 revert to the default settings when both the camera and the ST-E2 are set to auto power off.
Fixes a phenomenon in which the Macro Ring Lite (MR-14EX, MT24-EX) and slave flashes do not sync while shooting wirelessly.

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).
Fixes the AF point-selection behavior of the C.Fn III-7 (Manual AF pt. selec. pattern) custom function when set to [1].
Fixes a phenomenon in which the AF point-selection does not scroll through the available AF point selections. This would occur when rotating from the AF point in the lower left.
Fixes the AF point display for the viewfinder electronic level when shooting in the vertical position.
Fixes a phenomenon in which the viewfinder Electronic Level incorrectly displays the high side of the camera.
Corrects misspellings in the Spanish and Thai menus for applicable products.

The camera will allow a longer period of operation before the high temperature warning indicator is displayed, and automatic shut down of the camera occurs, during Live View or when using EOS Movie functions.
When Auto ISO is used and Program Shift is applied, the ISO setting will be more stable and not change as frequently when the Main Dial is rotated.
Corrects a misspelling in the French-language menu. (Only for products with French menu options.)
Fixes a phenomenon in which vertical magenta-colored banding appears in still images taken in movie-shooting mode.
This only occurs when in Manual exposure mode and when the ISO speed is set to "H". Note that this phenomenon only affects units with Firmware Version 1.2.0.

Fixes a phenomenon that in images captured by continuous shooting, and under certain conditions, barely noticeable traces of the immediately preceding frame may be visible.
This phenomenon is not noticeable in an image with optimal exposure. The phenomenon may become more noticeable if a retouching process such as level compensation is applied to emphasize the image.

Improves AF accuracy during Live View shooting.
This firmware improves the AF accuracy of the AF mode, Live mode, and Face detection Live mode during Live View shooting.
Fixes a phenomenon where in rare instances, movie images shot by the camera may exhibit abnormal colors.
Fixes a phenomenon that at certain timings, the shutter cannot be released when the camera's built-in flash or an external Speedlite is used for shooting.
This firmware corrects a phenomenon that in rare instances, the shutter cannot be released after the AF assist beam fires when the camera's built-in flash or an external Speedlite is used for shooting. Firmware Version 1.0.8 or later addresses this phenomenon.

Then you are quite a bit back, compared to the current version. Update to 2.0.5, or at least 2.0.3 and you'll get a whole set of improvement to your camera. Don't forget to download the new user's guide as well, since these changes are so extensive that they've made a new book too.
