Panasonic Lumix S1R II Mirrorless Full-Frame L-Mount Camera Body, Black {44.3MP}

44.3MP full-frame workhorse built for hybrid shooters who mean it.

The S1R II centers on a 44.3MP full-frame BSI-CMOS sensor paired with a 779-point Phase Hybrid AF system, a meaningful departure from the contrast-detect-only approach that defined earlier Lumix S bodies. At 40 fps continuous shooting, it keeps pace with action that most high-resolution cameras would struggle to track. The ISO range runs from 80 to 102400, giving you both the clean base-level sensitivity that landscape and studio work demands and the headroom for low-light editorial situations.

On the video side, 8K 10-bit recording with ProRes and ProRes RAW output puts this camera in conversation with dedicated cinema tools. The full-sized HDMI port and USB 3.2 Gen 2 connection at 10 Gbps mean your external recorder and fast offload workflow are both covered without adapters. Eight stops of Dual IS 2 stabilization handles handheld video that would otherwise require a gimbal, and the 5.76-million-dot EVF at 0.78x magnification is one of the better optical experiences available in a mirrorless body at any price point.

For L-Mount shooters who pushed the original S1R as far as it would go, the S1R II answers the two biggest asks: real phase-detect AF and competitive burst speed, without sacrificing the resolution that made the line worth building around.

Who It's For

Commercial and editorial photographers working at 44.3MP will find the file quality and dynamic range hold up through heavy retouching. Wildlife and sports photographers who need resolution alongside speed get 40 fps with a phase-detect AF system capable of tracking erratic subjects. Hybrid shooters producing broadcast or agency-deliverable content can lean on ProRes RAW output and 8K 10-bit recording without an external recorder. Travel photographers and documentary workers benefit from 8-stop IBIS and the fully articulated touchscreen, which allows low-angle or overhead framing without compromising stability.

FAQ

How does the S1R II's autofocus compare to the original S1R?

The S1R II replaces contrast-detect-only AF with a 779-point Phase Hybrid system, giving you tracking performance that matches current action cameras while retaining the 44.3MP resolution that made the line worth using.

Can you shoot 40 fps continuously at full 44.3MP resolution?

Yes. The 40 fps burst rate applies to the full 44.3MP output - no pixel-binning or crop needed.

What's the practical difference between 8K 10-bit video and standard 8K?

10-bit gives you 1.07 billion color values per frame instead of 256 million, which matters when you're grading heavily or recording in challenging light. ProRes and ProRes RAW output mean you're not stuck with H.265 compression either.

Does the Dual IS 2 stabilization work with non-stabilized lenses?

The 8-stop rating applies to sensor-shift stabilization alone. Non-stabilized L-Mount lenses will use only the in-body IBIS; stabilized lenses stack both systems for additional headroom.

How fast is USB 3.2 Gen 2 for offloading 8K footage?

10 Gbps sustained transfer means roughly 1.2 GB/s. You can offload 8K ProRes files to external storage nearly in real time without waiting for card-to-computer transfers.

Is the 350-shot battery life sufficient for hybrid shooting?

CIPA rating assumes continuous LCD use at 23°C. Shooting with the EVF off or in cooler conditions extends this meaningfully. Carry a second DMW-BLK22 battery for full-day video or event work.

What's the viewfinder like for manual focus work?

The 0.78x magnification with 5.76 million dots is bright and detailed, though experienced MF users will notice it's not quite 1:1 - expect to use focus peaking or magnification assist for precise focus checking.
