Leica SL2 Firmware 6.3.0

Leica SL2 Firmware 6.3.0 is the firmware update 6.3.0 published by Leica for the Leica SL2 family (SL2 and SL2-S). It replaces the previous release and is distributed from the manufacturer's official downloads page, which also carries the version documentation.

Version 6.3.0 ships for the SL2 and SL2-S; the manufacturer does not detail the specific changes in this release.

Installation happens on the device itself, not from a computer: download the file, copy it to a formatted memory card, insert the card in the device and follow the menu procedure. Before starting, check the installed version; if it already matches 6.3.0, the operation adds nothing.

Use a charged battery during the process, do not switch the device off and do not remove the card, then review the settings once it finishes. Leica SL2 Firmware 6.3.0 can be installed straight over earlier versions without intermediate steps.

It is worth updating before an important session rather than in the middle of a job: the camera is out of service for a few minutes and settings may need a check. If the camera is used with several lenses or accessories, reviewing the settings after the update helps confirm everything behaves as before. Leica recommends keeping firmware current to avoid faults that have already been fixed.
