Leica sl3 s vs panasonic lumix s1 ii?

Both of these are 24-megapixel full-frame mirrorless bodies on the L-Mount, announced in 2025, with stabilisation in the body. The resolution is a wash, so the choice comes down to how you shoot.

The Leica SL3-S is the one I'd pick for video. It has phase-detection autofocus and 6K open-gate recording. The Panasonic Lumix S1 II uses a partially stacked sensor for fast readout and is aimed at hybrid and video work, so it's the more practical all-rounder if you want to shoot both stills and video.

Because they share the same L-Mount, the lens list is identical. For a sensible everyday kit, I'd start with the Panasonic Lumix S Pro 24-70mm f/2.8, the Panasonic Lumix S 50mm f/1.8 and the Sigma 35mm f/1.4 DG DN Art. If you're new to sensor sizes, sensor sizes explains why full frame matters here.
