Panasonic is releasing a firmware update for its Lumix DC-S1 and S1R full-frame mirrorless cameras, which will be available on July 9th. The new firmware (version 1.1) addresses the following:

Improved image stabilization performance: Panasonic claims that with firmware v1.1, the in-body IS system will reduce shake by an additional 1/2-stop, for a total of 6 stops with non-stabilized lenses and 6.5 stops with Dual IS-compatible glass.

Improved AF performance: Panasonic claims that tracking performance live view display will be improved, and new AF-on options have been added.

  • Tracking performance during video recording has been improved
  • Live view display during autofocusing is now 'easier to see'
  • A new AF-ON: Near Shift biases toward close subjects, while Far Shift does the opposite

Two smaller changes: An 'activate' option has been added to the S1, for entering the key for the optional DMW-SFU2 video feature update. 'Operational stability' when using XQD cards should also be improved on both the S1 and S1R.

The firmware will be available for download on Panasonic's website on the 9th.


On the same day, firmware updates will be made available for six Micro Four Thirds cameras: the Lumix GH5, GH5S, G9, G90/G91/G95, G80/G81/G85 and GX9.

The new firmware addresses various things across those cameras, but the one thing they have in common is adding support for smooth aperture control during video capture when using the Panasonic Leica 10-25mm F1.7 lens. Users can also toggle the aperture ring between 'smooth' and 1/3EV. The minor camera-specific changes can be found in the press release below.
