Can I use Leica M lenses on a Leica SL?

Yes, with the Leica M-Adapter L. M lenses focus manually on the SL and the body reads 6-bit coding; focus peaking and viewfinder magnification make manual focus easy, and the SL2 and SL3 add in-body stabilization for them.

Are Sigma and Panasonic lenses compatible with the Leica SL?

Yes. The SL uses the L-mount, shared through the L-Mount Alliance, so Sigma and Panasonic L-mount lenses mount and autofocus natively, often at a fraction of Leica SL lens prices.

Do Leica R lenses work on the SL?

Yes, via the Leica R-Adapter L, with manual focus. The SL was popular with R-lens owners as a high-quality digital home for that glass.

What lenses fit the Leica SL: L-mount, M, and R adapters

One of the best things about the Leica SL system is how many lenses it accepts. Every SL body, from the original SL (Typ 601), the SL2 and SL2-S, to the current SL3 and SL3-S, uses the same L-mount and takes the same native and adapted lenses. Here is the full picture.

Native L-mount lenses (autofocus)

The SL uses the L-mount, which Leica shares with Sigma and Panasonic through the L-Mount Alliance. That means three sources of native, autofocus lenses:

All of these autofocus on any SL body. If you want fast autofocus, note that the SL3 and SL3-S add phase detection, while the older SL, SL2, and SL2-S use contrast detection, see the SL bodies compared.

Leica M lenses (manual focus, via adapter)

With the Leica M-Adapter L, the SL becomes a first-class digital home for M glass. M lenses focus manually, but the SL makes that easy with focus peaking and instant viewfinder magnification, and the adapter passes 6-bit lens coding so the camera records the lens in the file. On the SL2 and SL3 generations, in-body stabilization works with adapted M lenses too, a real advantage over a film M or a non-stabilized body. This is one of the most popular ways to use the SL.

Leica R lenses (manual focus, via adapter)

Leica's older R-mount SLR lenses adapt with the R-Adapter L, again with manual focus. Many R-lens owners bought into the SL specifically to keep shooting that glass on a modern sensor with a great viewfinder and, on later bodies, stabilization.

The bottom line

Whatever SL body you choose, you are not locked into expensive native glass: you can mix affordable Sigma autofocus lenses, your existing Leica M collection, and vintage R lenses on the same camera.
