Can I use adapted lenses on the leica sl3 s?

Probably, yes. The SL3-S takes L-Mount lenses, and mirrorless mounts are shallow, so old manual-focus lenses adapt easily and cheaply. It's a fun way to try fast or unusual glass, as long as you're happy focusing by hand. The adapters notes explain the idea.

I can't vouch for any particular adapter here, so check that it's made for L-Mount and that the lens you have in mind works with it before you buy. The third-party lenses notes cover checking brand support too.

If you'd rather stay with native autofocus, the Leica SL3-S page lists plenty of L-Mount lenses. For everyday shooting, I'd start with the Leica Summilux-SL 50mm f/1.4 ASPH or the Sigma 24-70mm f/2.8 DG DN Art.
