The EOS 5D Mark III is a completely re-engineered DSLR camera that boasts improved photo and video capabilities over its predecessor, the EOS 5D Mark II, and continues to address the demanding needs of professionals in still photography, cinema and television. The new firmware update adds two highly useful features: a clean HDMI output option and cross-type AF at f/8.
CANON vừa phát hành bản cập nhật Firmware 1.2.1 dành cho máy CANON EOS 5D3. Một số cải tiến trong bản cập nhật Firmware lần này là:
Clean HDMI OutPut
Cross-type AF Available for Maximum Apertures as Small as F/8To benefit DSLR cinematographers, the EOS 5D Mark III will
now be able to record clean, uncompressed digital video with embedded time code over HDMI output while simultaneously displaying the video on the rear LCD display and recording to internal CF or SD cards. Combined with an improved color sampling of YCbCr 42 8-bit video, this firmware update adds efficiency to video editing, improves color grading options, and enhances on-set monitoring.
The new “mirroring” feature via the HDMI output allows video to
be displayed on the rear LCD screen with or without scene and camera information while also outputting a clean video signal to
a monitor or external recorder. An external recorder not only enables a video signal devoid of compression artifacts, but also allows a choice of preferred edit-ready codec, the ability to shoot in a variety of frame rates and bit rates, and longer record time. Combined with the heightened color correction capabilities as a result of the expanded color space, post-production workflows will be smoother and offer users greater control and quality. With external recorders it is also possible to use a variety of on-set monitoring solutions, which facilitate real-time viewing of
EOS 5D Mark III video with the Rec. ITU-R BT. 709 color matrix. Additionally, it will now be possible to synchronize the start and stop of EOS 5D Mark III video capture with the start and stop of the external recorder.
The new firmware allows cross-type autofocusing with the center AF point when the maximum aperture becomes as small as f/8, in the same way that the EOS-1D X does.
If AF point expansion is selected with an f/8 maximum aperture lens/extender combination, the four AF points surrounding the center point will
act as AF Assist points. This option effectively expands the size of the AF detection area to enhance autofocus performance with subjects that appear small in the viewfinder and difficult to track, such as small animals and birds in flight. AF points above and below the center will be sensitive to vertical contrast, while points to the left and right will be sensitive to horizontal contrast.

Những thay đổi nhỏ khác
Firmware Version 1.2.1 incorporates the following functional improvements and fixes.
1. Uncompressed HDMI output is now enabled.
2. Enables the center AF point to autofocus when the camera is used with Canon EF lens/extender combinations whose combined maximum aperture is f/8.
3. Improves the speed of the camera’s acquisition of focus when using a Canon Speedlite’s AF-assist beam.
4. Fixes a phenomenon in which the LCD monitor may freeze and display Err 70 or Err 80 when a still photo is taken during Live View or in movie shooting mode.
5. Fixes a phenomenon that may occur when the continuous shooting priority setting is enabled for multiple exposures, such that, after the sixth image is taken, there is a slight pause before the remainder of the sequence is completed.
6. Fixes a phenomenon in which the viewfinder display shows incorrect information during AEB shooting.
7. Communication with the WFT-E7 Wireless File Transmitter has been improved.
8. When images have been successfully transferred with the WFT-E7 Wireless File Transmitter through the FTP protocol, an “O” will be displayed. When images have not been successfully transferred with the WFT-E7 Wireless File Transmitter through the FTP protocol, an “X” will be displayed.
9. Fixes a phenomenon in which the camera may not function properly when an Eye-Fi card is used.
10. Fixes a phenomenon in which the focal length value listed in the Exif information is not displayed correctly for images shot with the EF 24-70mm F4L IS USM lens.
11. Fixes a phenomenon in which the lens firmware cannot be updated properly.
12. Corrects errors in the Arabic language menu.
13. Fixes a phenomenon in which the camera changes the AF microadjustment value to -8.
14. Fixes a phenomenon in which the on-screen guidance cannot be fully displayed when setting the maximum limit value for the “Setting the ISO Speed Range for Auto ISO” option.
* Items No.1 through 12 have been incorporated into firmware version 1.2.0.
* Items No.1 through 14 have been incorporated into firmware version 1.2.1.
Firmware Version 1.2.1 is for cameras with firmware version 1.2.0 or earlier. If the camera’s firmware is already version 1.2.1, it is not necessary to update the firmware
