The new engine gives the LUMIX S5IIX and S5II video recording capabilities including internal 4:2:0 10-bit 6K (3:2) and 5.9K (16:9) at 30 fps and 4:2:2 C4K and 4K at up to 60fps, while a new low-profile heat management system allows for unlimited recording times without increasing the size of the camera body. The cameras also support HFR (High Frame Rate) recording at up to 120 fps and Slow & Quick capture at up to 180 fps.

The LUMIX S5IIX model is capable of 5.8K Apple ProRes recording to SSD via HDMI or USB, and ALL-Intra Recording. Additionally, the S5IIX can support Apple Pro Res RAW video output to Atomos. It also supports wired and wireless IP streaming and USB tethering. A range of picture profiles including 14+ stop V-Log/V-Gamut are available on both models, as well as a new Real-Time LUT function enabling colour grading LUTs to be uploaded to an SD card and directly applied in-camera rather than in post-production.

Thanks to host of new and improved features, the LUMIX S5IIX and S5II are able to deliver truly astounding photo and video performance, including high-speed burst shooting at up to 9 fps with mechanical shutter and 30 fps with electronic shutter (capable of capturing up to 300 images), a 96-megapixel High Resolution Mode (JPEG/RAW) and Dual Native ISO sensitivity, which minimises noise and allows a maximum ISO of 51200 (204800 when Extended).

The LUMIX S5IIX and S5II also boast an upgraded image stabilisation system to greatly enhance handheld shooting in a wide range of conditions and situations. The new Active I.S. provides highly stable video recording by optimising horizontal, vertical and rotational correction. Compensating as much as 200% compared to conventional stabilisation, Active I.S. is especially effective in traditionally challenging conditions for handheld shooting, such as using telephoto lenses or filming while walking.

Connectivity has been improved over the LUMIX S5, with the LUMIX S5IIX and S5II each featuring a full-size HDMI Type A terminal and high-speed USB 3.2 Gen 2, plus a cable lock holder to prevent unwanted unplugging. Wireless connectivity has been improved too, with Wi-Fi 5GHz joining 2.4 GHz to provide fast, stable communication with smartphones and tablets.

Dual card slots (both UHS-II) support Relay Recording, Backup Recording and Allocation Recording and the 2200mAh high-capacity battery can be recharged via AC or USB.

Users will be able to further enhance LUMIX S5IIX and S5II performance through a future firmware update, which will add a host of functions including RAW data output and Live View Composite.
