Panasonic's high-resolution L-Mount mirrorless — 47.3MP full-frame with IBIS and High Res mode.
The Panasonic Lumix DC-S1R was released in 2019 as the high-resolution L-mount full-frame mirrorless, featuring a 47.3MP full-frame CMOS sensor with 6-stop IBIS and 4K video. The S1R pairs the highest L-mount resolution at launch with Panasonic's V-Log colour science. DMW-BLJ31 battery. At approximately 1,020g with battery and card.
47.3MP full-frame CMOS sensor. 6-stop IBIS (6.5-stop Dual I.S.2 with compatible OIS lenses). 4K/60fps (slight crop); 4K up to 30fps full-width; 10-bit 4:2:2 via HDMI out (internal is 8-bit 4:2:0). HLG and V-Log. DMW-BLJ31 battery (~380 shots). Body weight approximately 1,020g with battery and card. Dual card slots (XQD/CFexpress B + SD UHS-II).
The S1R's 47.3MP sensor enables the High Resolution Shot mode for composited 187MP images via pixel-shift — useful for architecture, product, and fine art photography where extreme detail resolution exceeds the native 47.3MP output. The V-Log colour science provides the grading latitude for professional video workflows. The 4K 60fps crop caveat: full-sensor-width 4K requires 30fps or below.
On the used market the Panasonic S1R is available at professional L-mount high-resolution pricing. Condition checks: IBIS operation, DMW-BLJ31 battery health (shared with S1/S5 series), dual card slot contacts, and weather sealing. Compatible with all L-mount lenses.
