Using non-Leica L-mount AF lenses on a Leica SL/SL2

I have a few Panasonic and Sigma L-mount AF lenses to use with my Pana S1 and S1r.

I recently bought a used Leica SL. It has firmware 3.7 installed. When I mounted my Panasonic 50/1.4 Pro S lens on the SL it appears that only the Aperture Priority and Manual exposure modes are available. Does anyone know if this is the case for all non-Leica AF L-mount lenses on a SL? Perhaps I don’t have a custom setting correctly set on the SL. I was hoping/expecting that most of the main camera functions would be available on L-mount cameras from Leica, Panasonic and Sigma when their respective L-mount lenses are mounted on the various L-mount cameras available to us.

Is that the newest firmware? I believe there was updated firmware released after the other memebers of the L-Mount shipped their products.

Yes, I think 3.7 is the latest update from February 2020.

That’s weird. I hadn’t heard of any issues with the SL and L-Mount lenses since early on. I believe there was an update to the lens mount standard that mostly centered around adding protocols to deal with IBIS and the newer lens offerings from partner companies. Is there a way to check the lens firmware too on the SL? There may be a an update for the lens as well.

You may have a bit of better luck on LUF in the “other L-Mount camera section” as many people are using the newer lenses on Leica bodies.

I received the Sigma 45mm f2.8 DG DN L-mount lens today (very nice build quality and compact size), mounted it on my SL and just as with the Panasonic 50mm f1.4 S Pro lens, the only camera exposure modes which are available are A and M, Aperture Priority and Manual.

I'll see if I can check the lens firmware and update it as needed. Thanks for that suggestion!

Surprisingly, when I mount my Leica R lenses with the Novoflex adapter attached onto the SL, all exposure modes are available (A, M, S and P). I would have expected only A & M modes to be available with the Leica R lenses and "dumb" Novoflex adapter attached.

That’s really weird. I only have the S1R and a Panasonic lens (24-105) for now. Still trying to figure out what I want next but I’m leaning towards the Lumix S Pro 50/1.4 and maybe the 35 APO-Cron if they ever come in stock.
