Panasonic's updated all-rounder L-Mount body — S1 successor with phase-detect AF and improved features.
The Panasonic Lumix S1 II was released in 2024 as the second-generation L-Mount full-frame mirrorless, featuring a 24.1MP partially stacked CMOS sensor, 8-stop IBIS (Dual I.S. 2), and 4K/120fps video. DMW-BLK22 battery. At approximately 800g with battery. Near knowledge cutoff — verify current specifications.
24.1MP full-frame partially stacked CMOS. 6K/30fps open-gate (3:2); 5.1K/60fps; 4K/120fps 4:2:0 10-bit; 1080p/240fps. 8-stop IBIS (5-axis Dual I.S. 2, CIPA; up from 6 stops in original S1). DMW-BLK22 battery (2200mAh; distinct from original S1's DMW-BLJ31). Approximately 800g with battery. L-Mount.
The S1 II's partially stacked CMOS is the key sensor upgrade over the original S1 (which used a standard BSI CMOS): the partial stacking enables faster sensor readout for higher video frame rates (4K/120fps) and improved rolling shutter performance. The 8-stop IBIS and revised video feature set position it as a genuine hybrid stills-video body in the Panasonic S line.
On the used market the Panasonic Lumix S1 II is available at Panasonic S-series full-frame pricing. Condition checks: DMW-BLK22 battery health (different from original S1 battery), 4K recording function, IBIS operation. Note: 2024 product — verify specifications. Compatible with all L-Mount lenses.
