Leica Firmware Update v3.1.1 for SL3 and SL3-S

Today, Leica has released firmware version 3.1.1 for the SL3 and SL3-S. This update introduces new C6K and C4K ProRes 422 HQ internal video recording for the SL3, expands autofocus functionality, and brings back joystick magnification. Additional improvements focus on enhancing user interface controls, streamlining the firmware update process and expanding electronic shutter options.

As always, we recommend updating your camera to the latest firmware to take advantage of new features and system optimizations. Download links and installation instructions are provided below. Of course, you can also update via the latest Leica FOTOS app as well.

New

EU Eco-Design Compliance

The SL3 and SL3-S now comply with the requirements of Lot6 and Lot26 under Regulation (EU) 2023/826, ensuring compliance with the latest environmental standards.

New Video Formats for C4K and C6K for the SL3

This update adds new video recording formats for C4K (4096 x 2160) and C6K (5776 x 3056) on the SL3, providing more creative options for professional video workflows and bringing it in line with the SL3-S. These are all the new available formats, which can be saved internally if using a Compact Flash Express (CFe) card.

Improvements

Headphone Volume Control

The Headphone Volume setting is now accessible through the Audio section of the Video menu and can also be assigned to a function button for quick adjustment.

Joystick Magnification Control

The joystick can now activate and deactivate the Magnification function for manual focus lenses, making it faster and more intuitive to check focus accuracy during shooting. Leica listened to customer feedback here, bringing back a core function from previous SL generations.

Control Center Icon Assignments

When changing icon assignments in the Control Center, the function assignment list will now open directly to the currently assigned option, speeding up menu navigation.

Leica Looks Menu Update

The former Film Style and Video Style menus (previously accessible via JPG Settings) have been integrated into the Leica Looks menu and are now directly accessible from the Main Menu.

Firmware Update Process

The update process has been optimized. Previous settings will now remain unchanged after an update, and the “Save profiles on SD card?” prompt has been removed. A battery charge level of just 25% is now sufficient to start the update. Such a welcome addition and will make updating in the future that much easier.

Electronic Shutter Improvements

The maximum electronic shutter speed of 1/16,000 second is now available in Program (P) and Aperture Priority (A) modes, offering greater control for bright environments without the need for ND filters.

Expanded AF-ON Functionality

The AF-ON button can now be used in combination with Eye/Face/Body Detection and Animal Detection, improving autofocus behavior across a wider range of shooting scenarios.

Error Corrections

User Profile Indicator

An icon with an asterisk now appears next to the User Profiles icon in the Control Center and sidebar to indicate if any settings have been modified after activating a profile.

AF-ON Included in User Profile

In cases where AF-ON has been assigned to the joystick, this setting will now be correctly saved to user profiles.

Download Firmware Files

To download the firmware file, simply click the buttons below. You'll need to drag and drop the downloaded firmware file onto an SD card which was freshly formatted in the SL3-S, then insert the card into your camera with a fully charged battery. Navigate to the Camera Information menu to access the firmware update option. Don't try to open the firmware file on your computer – just copy it onto the SD card into the root directory. Full step-by-step instructions are below.

Alternatively, you can also update via the Leica FOTOS app if paired with your SL3 or SL3-S camera.
