Leica SL3 Firmware v1.1.9 Fixes Image Overwriting Bug

Today, Leica has released a critical firmware update for the SL3. This firmware update addresses a bug that Leica publicly acknowledged last week where images could be overwritten on the memory card following a battery change when the camera wasn't fully powered down. While not every user encountered the problem, this was a major issue and some users did lose images. Thankfully, once the problem was identified, Leica was responsive in issuing a public warning and rolling out a firmware fix in a matter of days. Along with addressing the core issue, Leica has also included a few minor bug fixes and improved the connection to Leica FOTOS. We strongly recommend installing this update as soon as possible to avoid any accidental loss of images.

Change Log

Error Correction

• Sporadic error that resulted in unnoticed overwriting of existing recordings if the camera was not properly turned off beforehand (e.g., during battery replacement in standby mode or after an unexpected software interruption).
• Correction of errors in the firmware.

Improvement

• Optimization of the Leica FOTOS connection.

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, 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.
