Sony issued a new major firmware update for the Sony A7III (download here) and Sony A7rIII (download here).

A7III an A7rIII: Benefits and Improvements from the latest update

Support of “SEL400F28GM”and “SEL24F14GM”

  • Optimization of the optical image stabilization performance, and addition of a new image stabilization mode of the lens (Mode 3)(Only “SEL400F28GM”).
  • Addition of a Function Ring(Lens) to the menu.
    Note: For the SEL400F28GM lens, the APS-C S35/Full Frame Sel. setting is assignable to the Function Ring in addition to Power Focus.
  • Addition of [Aperture Drive in AF] setting in the menu.
    *Using the lens “SEL400F28GM” or “SEL24F14GM”, when [Silent priority] is selected, the sound emitted by the aperture drive will be reduced. This is useful in shooting conditions where camera.
    noise should be kept to a minimum. Note that Auto Focus may become slower when [Silent priority] is selected.

New features:

  • [AF Track Sens] can be assigned to a custom key.
  • When used with the LA-EA3 mount adaptor [link to product page], all focus areas are supported.
    Note : Focus Area options added : Zone, Expand Flexible Spot, and Lock-on AF.
    Bracket shooting is available during silent shooting when [File Format] is set to [RAW] or [RAW & JPEG] and [RAW File Type] is set to [Uncompressed].

Other improvements:

  • Improvement of the performance and the overall stability of the camera.
  • Better reproduction of the gradation of RAW pictures.
    Note: Imaging Edge software needs to be updated to benefit from the improvement in the RAW processing.
  • When shooting with a flash in an environment with flickering light sources, the stability of the exposure is improved.
  • Improvement of managing continuously shot images as a group.
    Please refer to the HelpGuide for updated function usage.

I wonder that that “Better reproduction of the gradation of RAW pictures” means!

UPDATE: Maiku reports there’s a problem with the OSX updater for the a7iii and the a7riii update file.  He found a fix and made a video:
