S1II and S1II users get several of these features in firmware v1.1 for their cameras. S1RII additional features The S1IIR gains 8.1K open gate recording capability, along with the ability to output a Raw data stream that can be encoded by BlackMagic or Atomos external recorders. At launch the camera downsampled its open gate output to 6.2K resolution. The new firmware allows the full sensor area output Panasonic said it would add. It also gains the 'Urban Sports' subject recognition autofocus mode introduced on the S1II models, along with the ability to output 10-bit HEIF images, including HDR images using the HLG response curve. The update also includes an HLG View Assist mode for previewing the effect. A significant suite of other feature tweaks and enhancements includes additions such as file transfer from internal cards to an SSD, UVC/UAC compatibility and the option to use the focus ring on some lenses as a control ring. Upgrades for S1RII, S1II and S1EII The update also includes a range of features that also come to the S1II and S1IIE, as part of their firmware v1.1. These include an in-camera focus stacking mode, that combines images focused at different distances, to increase depth-of-field, and the abilitly to change the color of the AF focus frame. Users of all three cameras will be able to install a paid upgrade to shoot ARRI LogC3 Users of all three cameras will also be able to install a paid upgrade enabling the shooting of footage using ARRI's LogC3 color and luminance response, allowing its use alongside ARRI cameras and using LUTs designed for those cameras. The new firmware also adds seven extra aspect ratio guides and allows up to three to be shown at the same time, to help when composing for output in multiple aspect ratios. All three cameras also gain the ability to communicate via Wi-Fi or wired LAN (via a USB adapter) with Capture One software. Firmware v1.2 for the Panasonic Lumix S1RII and firmware v1.1 for the Panasonic Lumix S1II and S1IIE will be available from June 24th on Panasonic's Global Customer Support website.
