It is as follows:

Leica lenses update automatically on Leica cameras - if an update is needed! -

Sigma lenses  can be updated from Sigma's website through the USB Dock 

Leica lenses when used on Panasonic/Sigma cameras can be updated using a Leica camera.

Jaap, 

Do you happen to know if Panasonic L mount lenses update on a Leica CL/SL body? I would assume not and I would have to find someone with a Panasonic L mount camera to get my Panasonic 70-200mm lens updated. I believe there is at least one FW update for this lens, which I bought not long after it was released.

Installation instructions for the L-Mount lens firmware on Leica SL, Leica SL2, and Leica SL2-S cameras can be found here. https://l-mount.com/webfile/show/EN_FW_UPDATE_L-MOUNT.pdf

Both Leica and Panasonic are less than clear as to whether the Firmware update for example for the Panasonic 70-200 L mount lens will run on a Leica Camera. I am very reluctant to try running an FW update from a different manufacturer on my CL, as it might totally screw up that camera, unless both manufacturers state unequivocally that it is OK. I have downloaded the FW 1.2 for my 70-200 lens but feel it would be a big risk to run this.
