Lumix S9 Firmware 2.1 Update: Lens Fn Boosts & MP4 Lite, But Urban Sports AF Misses Out

Firmware Update Alert: Panasonic has officially deployed Firmware Version 2.1 for the compact full-frame Lumix S9. While the release brings heavily requested operational upgrades—including expanded Lens Fn custom button controls and 4K60p MP4 (Lite) support—it notably leaves out the flagship Urban Sports AF tracking mode found on high-end S series siblings.

Panasonic continues its impressive streak of post-launch firmware support for its full-frame mirrorless lineup. The latest update, Firmware Version 2.1, brings significant usability improvements to the ultra-compact Lumix S9, designed to streamline mobile video workflows and give creators more tactile control through lens Fn buttons.

However, action-focused creators holding out hope for Panasonic’s advanced Urban Sports AF subject detection mode will find that the feature remains reserved for larger, high-performance bodies like the Lumix S1 II and S1R II.

Daisy’s Take: Don’t let the lack of Urban Sports AF discourage you! While it would have been awesome to have specialized parkour and trick-tracking AI on the S9, Version 2.1 makes the camera far more versatile for everyday videographers. Being able to map Focus Peaking or Crop Zoom directly to the Fn button on lenses like the new Lumix S 20mm f/2.5 is a huge functional win!

What’s New in Lumix S9 Firmware Version 2.1?

Firmware 2.1 is packed with updates aimed squarely at hybrid shooters, gimbal operators, and creators who rely on swift on-set adjustments:

  • Empowered Lens Fn Customization: Users can now assign ten critical camera functions directly to the physical Fn button on supported Lumix S lenses (including the compact Lumix S 20mm f/2.5). Assignable controls include Aspect Ratio, Video E-Stabilization, Boost I.S., Video Image Area, Focus Ring Control, Focus Limiter, Hybrid Zoom, Crop Zoom, Focus Peaking, and Video Record Start/Stop.
  • 4K60p & 1080p120 MP4 (Lite) Video Modes: The update adds high-efficiency 10-bit 4:2:0 MP4 (Lite) recording options up to 4K at 60p/50p and Full HD at 120p/100p. This provides significantly smaller file sizes designed for rapid offloading and mobile editing via the LUMIX Lab app.
  • LUMIX Flow App Integration (v1.7.0+): Full compatibility with the Lumix Flow mobile suite, turning connected iOS and Android devices into external video monitors with storyboard mapping, scripting, and director’s review controls.

Why Did Urban Sports AF Miss the S9?

When Panasonic introduced Urban Sports AF—a specialized deep-learning subject recognition profile built to track fast-moving human movement like skateboarding, parkour, breakdancing, and acrobatics—it quickly became a fan favorite on flagship bodies.

Many Lumix S9 shooters hoped the feature would trickle down in Version 2.1 given the camera’s popular status among urban street creators. However, thermal and processing limitations appear to be the main reason for its absence:

Feature / Spec Lumix S9 (Firmware 2.1) Lumix S1 II / S1R II / S5 II Series
Subject Detection AF Modes Human (Eye/Face/Body), Animal, Car, Motorcycle, Train, Airplane Human, Animal, Car, Motorcycle, Train, Airplane + Urban Sports AF
Custom Lens Fn Mapping Yes (10 New Assignable Modes) Yes
MP4 (Lite) 4K60p Support Yes Varies by model
Target Audience Travelers, Vloggers, Content Creators Action Photographers, Pro Cinematographers

The compact chassis of the S9 lacks active internal cooling fan hardware. Heavy neural-network processing requirements—such as those demanded by real-time Urban Sports AF tracking—generate significant heat during extended continuous video recording. By keeping AF detection focused on standard human, animal, and vehicle modes, Panasonic maintains stable operating temperatures inside the pocket-sized body.

Daisy’s Take: Remember that the S9 still features standard Deep Learning Human AF tracking (eyes, faces, bodies and torsos) as well as dedicated Airplane and Train detection modes added in earlier updates. For 95% of everyday street photography and casual action, the standard human tracking works fantastically well!


How to Install Firmware 2.1 on Your Lumix S9

You can update your camera using two simple methods:

  1. Via SD Card (Recommended): Download the `.bin` update file directly from the official Panasonic Global Support site, format your SD card in-camera, copy the file to the card’s root directory, and initiate the update from the camera’s Setup Menu.
  2. Via LUMIX Lab App: Pair your camera with the latest version of the LUMIX Lab app on iOS or Android, connect via Wi-Fi, and follow the on-screen prompt to transfer and run the update wirelessly.

Final Verdict

While the absence of Urban Sports AF might disappoint street sports videographers, Firmware 2.1 remains a solid, high-value release for Lumix S9 owners. The addition of custom Lens Fn options and high-fps MP4 (Lite) recording makes the camera significantly faster to operate on the fly. Head over to Panasonic Support today to update your body!
