Are the previous versions of firmware included in version 1.2.3?
Yes, the following improvements from the previous version are included:
(Previous) Version 1.2.2 improvements:
Firmware Version 1.2.2 includes the following improvement:
- 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.
(Previous) Version 1.2.1 improvements:
Firmware Version 1.2.1 includes the following improvement:
- 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.)
- Corrects 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.
(Previous) Version 1.1.0 improvements:
Firmware Version 1.1.0 includes the following improvement:
- Corrects 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.
(Previous) Version 1.0.9 improvements:
Firmware Version 1.0.9 includes the following fixes:
- 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.
- Corrects a phenomenon where in rare instances, movie images shot by the camera may exhibit abnormal colors.
- Corrects 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.
