松下发布其Lumix DC-S1和S1R全画幅无反光镜相机的固件更新，该相机将于7月9日上市。新固件（版本1.1）解决了以下问题：

改进图像稳定性能：松下声称，通过更新固件，相机机身的防抖将减少一半以上的震动，使用不带防抖功能的镜头最高可以减少6次震动，而使用防抖镜头则可以减少6.5次震动。

改进自动对焦性能：此次固件更新松下S1R还改进了自动对焦功能，增加了新的对焦选项，视频录制期间的追焦性能得到改善，自动对焦指示在取景器中的显示更明显。

S1中添加了“激活”选项，用于输入可选DMW-SFU2视频功能更新的密钥；使用XQD卡时的“操作稳定性”也在S1和S1R上得到改善。

该固件将于7月9日在Panasonic的网站上下载。届时，松下将为六台Micro Four Thirds相机提供固件更新：Lumix GH5，GH5S，G9，G90 / G91 / G95，G80 / G81 / G85和GX9。

新固件解决了这些相机存在的一些问题，当他们在使用Panasonic Leica 10-25mm F1.7镜头时，在视频拍摄期间增加了对平滑光圈控制的支持。用户还可以在“平滑”和1 / 3EV之间切换光圈环。

英文原文如下：Firmware update for Panasonic S1/S1R improves image stabilization and AF performance

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；

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.
