Panasonic released new firmware updates for the Lumix S5II, S5IIX, S9, G9 and GH7 cameras:
Panasonic Lumix Firmware Updates Released October 20, 2025
Panasonic has rolled out new firmware updates for the Lumix S5II (Ver. 3.4), S5IIX (Ver. 3.4), S9 (Ver. 1.6), G9II (Ver. 2.5), and GH7 (Ver. 1.5). These updates focus on enhancing usability for hybrid shooters and filmmakers, including faster performance, improved app integration, and expanded accessory compatibility. They also coincide with updates to the Lumix Lab and Lumix Flow apps, which add features like AI-powered Magic LUT for image look transfers and phone-as-monitor functionality. Below is a model-by-model recap of the key new features.
Lumix S5II (Ver. 3.4) and S5IIX (Ver. 3.4)
These full-frame hybrids receive shared enhancements emphasizing workflow efficiency and creative controls:
- Faster startup time: Reduces boot-up delay for quicker access to shooting modes.
- Lumix Flow app compatibility: Enables using a smartphone (iOS/Android) as a live monitor, with remote control for focus, exposure, and recording.
- Enhanced focus ring customization: The focus ring can now double as a control ring for aperture, ISO, or shutter speed adjustments.
- Improved Bluetooth support: Full integration with DJI RS 4-series gimbals for seamless wireless control.
- Live LUT previews and frame markers: Real-time LUT application during shooting, plus multiple overlay markers for precise framing (e.g., for social media aspect ratios).
- Hybrid zoom and MP4 Lite: Expanded crop zoom options in video modes, with lighter MP4 formats for easier file handling.
Lumix S9 (Ver. 1.6)
As Panasonic’s compact full-frame creator camera, the S9 gets usability tweaks to align it with the broader S-series ecosystem:
- Focus ring as control ring: Repurposes the ring for quick adjustments to key settings like aperture or ISO.
- Lumix Lab app enhancements: Better integration for image transfer, remote shooting, and the new AI Magic LUT feature (copy looks from reference images).
- Improved stability for app connections: Smoother Bluetooth/Wi-Fi pairing with Lumix Sync and Lab apps.
- Minor AF refinements: Subtle boosts to phase-detection accuracy in low light.
(Note: The S9 does not receive the startup speed improvement seen in the S5II/S5IIX, likely due to its lighter system architecture.)
Lumix G9II (Ver. 2.5)
This Micro Four Thirds speed demon gains parity with Panasonic’s video-centric lineup:
- Lumix Flow compatibility: Smartphone monitoring and remote control, including for the new 4:3 aspect ratio video crops.
- Enhanced subject detection: Adds recognition for planes, trains, and specific subject parts (e.g., a driver’s face in a car).
- Phase hybrid AF improvements: Borrowed from S5II updates, for more precise tracking in dynamic scenes.
- Bluetooth for DJI RS 4: Wireless gimbal control added.
- App workflow boosts: Full support for Lumix Lab’s Magic LUT and faster image transfers.
Lumix GH7 (Ver. 1.5)
Panasonic’s flagship Micro Four Thirds video camera builds on its pro tools with ecosystem-wide ties:
- Lumix Flow integration: Phone-as-monitor with live LUT previews and multi-frame markers.
- Improved startup and stability: Quicker boot times and overall system optimizations.
- Customizable focus controls: Enhanced ring functionality and subject-specific AF (planes, trains, etc.).
- DJI RS 4 Bluetooth support: For stabilized remote operation.
- Video aspect ratio options: New 4:3 crops for vertical/social formats, plus MP4 Lite for lighter exports.
These updates are free and available now via the Lumix Global Customer Support website or app stores. They also extend to select S-series lenses (e.g., 18mm f/1.8, 24mm f/1.8) for better operational smoothness. Panasonic notes future rollouts for S1II/S1RII/S1IIE models. For installation, back up your settings first, as some app authentications (e.g., Lumix Sync) now require per-session passwords for security.
