Today Leica has published firmware version v.4.0 for the Leica SL3 and SL3-S with significant new features and improvements. Here are the download links and the changes:

Downloads:

Alternatively, the firmware can be installed via the Leica FOTOS app.

NEW

  • A direct Camera-to-Cloud connection to Adobe Frame.io can now be established via WLAN, allowing photos and videos
    (proxy videos) to be uploaded directly to the cloud. This new function is located in the Connectivity menu, where both Leica FOTOS and Frame.io are now managed.
  • The tracking algorithm automatically adjusts the size and shape of the focus field during subject tracking. This results in more stable and reliable performance over extended periods of time.
  • Automatic focusing on human features, e.g. eyes and faces, has been significantly improved through AI-assisted models.
  • The AF mode was revised and the menu structure was simplified. Multi-Field and Spot were combined into one menu (Zone / Multi-Field
    and Field / Spot). A new AF Acquisition menu is now available in both the FN list and the Control Center. Expanded subject recognition: humans (eye/face/body) and animals – including birds, dogs, wolves, cats, and big cats.
  • The Leica Looks menu was optimized. A new Intensity setting option was added.
  • The monitor refresh rate can now be set to 30 fps / 60 fps. Selecting 30 fps reduces power consumption in Live View mode.
  • A new Battery Condition menu now displays the overall condition of the BP-SCL6 battery.
  • A Multi-Shot mode has been added for the SL3, Facilitating shots of up to 241 MP for maximum detail rendering.
  • Additional video formats with lower bit rates have been introduced, providing more flexible recording options. The camera now also
    supports the aspect ratios 4:3 (anamorphic) and 3:2, expanding creative possibilities.
  • When using an anamorphic lens, the camera can now de-squeeze distorted images during playback. Supported anamorphic desqueeze factors: 1.25, 1.3, 1.33, 1.5, 1.6, 1.65, 1.8, 1.85, 2.0.

IMPROVEMENT

  • The behavior of the Auto ISO display in Live View and the Control Center when using a flash was revised. - Previously, the camera
    sometimes displayed incorrect ISO values in flash mode, since the actual ISO value is only determined during the pre-flash. With the
    update, the following behavior applies:
    – If a flash is connected and required for the shot, the Auto ISO value remains hidden in Live View and the Control Center.
    – If a flash is connected but not ready or not required, a preview value is displayed.
    – If no flash is connected, the Auto ISO value is displayed as usual.
  • The AF profile labels (DE/EN) have been adjusted for clearer and more consistent terminology.
  • Change to the default flash setting: The default for Flash mode is now On instead of Auto
  • RED – EU Cybersecurity Requirements: When updating from version 3.1.1 or earlier, the camera must be re-paired with the app.
  • Default settings adjusted in Control Center: AF Detection is now enabled by default.
  • Faster Start Time (after extended inactivity): The camera starts up significantly faster.
  • When inserting an aged or low-performance battery, a warning message now appears indicating reduced battery condition.
  • The icon for active Perspective Control is now displayed correctly in Review mode.
  • The warning message regarding limited functionality when using a BP-SCL4 battery was revised. The message can now be disabled via the option „Don't show again“. After eight weeks, the reminder automatically reappears to indicate the battery condition. The message is displayed only when the camera is switched on, not when waking from standby. The setting is restored to default after a camera reset.
  • Starting a video recording no longer cancels a previously set autofocus lock. The focus setting is therefore maintained during the transition from photo to video mode.
  • The menu items File Format and Compression were consolidated and are now available via the single menu item (File Format).
  • Improved display of grayed-out settings: Current values will now always be shown in Live View and in the menu.

TROUBLESHOOTING

  • When switching on the camera, the message “No memory card inserted. Please insert a memory card” was previously displayed
    briefly, even though a card was present. This behavior occurred with SD and with CFexpress cards. This issue was resolved. The
    camera now recognizes the inserted memory card without error messages.
  • Autofocus with S-lenses now operates significantly more reliably and consistently, especially in combination with the SL3-S.
  • In Tethered shooting mode with JPG+DNG files, Leica Content Credentials data was previously not stored. This issue was resolved.
    The Content Credentials information is now properly embedded in both file formats.
  • Thanks 3

finally, this is something I have been suffering for the long time.

Even though I did the update and paired, the Fotos app said I still needed to update the Bluetooth pairing... I tried this, and got nowhere, including deleting the bluetooth pairing on the phone - kept showing the same message. I had to delete my phone pairing in the SL3-S and the SL3-S from Fotos and start anew, and seem fine now

Same here with my SL3, had to delete the camera profile. Didn't use the Cable, did it over wifi/bluetooth.
