Canon has announced a range of firmware updates for its higher-end DSLRs.
Firmware update 1.2.3 for the EOS-5DmkIII, which has just been released, is a maintenance release that improves “microadjustments” to the auto focus, brings improvements to the LCD monitor and to flash triggering.
For video pros, the most important update is a fix to the HDMI out, which allows camera LCD adjustment, and the correct display of histograms, even when the camera is connected to an external LCD device.
The EOS-1D X gains version 2 firmware, with new AF modes and changes that make the Auto ISO modes more flexible by adding minimum shutter speeds and exposure compensation. The update is a download, and will be available early next year.
The EOS-1D C update is more complex, as it requires owners to send their cameras to a Canon service centre for updating, although this is free of charge.
The improvements include new audio options, especially a line-level input, and aberration correction (which Canon calls Chromatic Aberration Correction) for the Cinema EOS line of lenses. The new firmware will also allow the camera to display the current aperture when using Cinema EF lenses.
The 5DmkIII firmware is available via Canon’s support site.
