FIRMWARE UPDATES
Leica is continuously working on the further improvement and optimization of your camera.
Since many camera functions are entirely controlled by software, some of these improve-
ments and additions to the functional scope can be installed in retrospect. Leica offers firm-
ware updates at irregular intervals, which you can download from our website.
Leica will notify you of any new updates, once you have registered your camera. Users of
Leica FOTOS will also be automatically notified about firmware updates for their Leica
cameras.
There are two options for installing firmware updates.
–conveniently via the Leica FOTOS app
–directly via the camera menu
Finding the currently installed firmware version
→Select Camera Information in the main menu
• The current firmware versions are displayed.
More information about registering, firmware updates and how to download them to your
camera, as well as any amendments and additions to this manual can be found in the cus-
tomer area of our website at:

EXECUTING A FIRMWARE UPDATE
Any interruption of a running firmware update may cause serious and irreparable damage
to your equipment!
You will therefore have to take particular note of the following, when carrying out a firm-
ware update:
• Do not switch off the camera!
• Do not remove the memory card!
• Do not remove the rechargeable battery!
• Do not detach the lens!
Notes
• A warning message will appear if the battery is insufficiently charged. Recharge the battery
and then repeat the process described above.
• You will find additional device and country-specific registration marks and numbers in the
Camera Information submenu.
PREPARATION
→Fully charge and insert the rechargeable battery
→The second SD memory card (where applicable) must be removed from the camera
→Any stored firmware files on the memory card must be removed
• We recommend saving any images on the memory card and reformatting it before the
update.
(Caution: Loss of data! All data stored on the memory card will be lost during formatting.)
→Download the latest firmware version
→Save the download to the memory card
• The firmware file must be stored in the main directory of the memory card (not in a
sub-directory).

UPDATING THE LENS FIRMWARE
Where available, firmware updates can be performed for Leica SL lenses and for all other
lens types by L-Mount Alliance.
Firmware updates for Leica SL lenses are generally uploaded alongside the latest version of
the camera firmware and will not have to be implemented manually. Provided an SL lens is
attached during the camera update, it will automatically receive the latest firmware version.
Where that is not the case, a relevant prompt will appear when a lens is attached to a cam-
era with updated firmware for the first time.
The instructions provided for camera firmware updates apply.
