The Next Evolution of Precision, Detail, and Dynamic Range

The Panasonic LUMIX S1R II Full Frame Mirrorless Digital Camera marks a massive leap forward in Panasonic’s legendary LUMIX S-Series lineup. Designed for hybrid shooters who demand the absolute best in both stills and 8K video, this camera blends unmatched image resolution, cinema-grade recording, and robust professional ergonomics into a single body that sets a new benchmark for 2025.

With its 44.3-megapixel full-frame CMOS sensor, LUMIX’s first-ever 8K recording capability, and refined Dual I.S. 3 stabilization system, the S1R II proves Panasonic is ready to challenge the very best from Sony, Canon, and Nikon—head-on.

Lifelike Detail with the New 44.3MP Sensor: Capture landscapes, detailed artworks, & everyday moments with unique color science & a lifelike feel in this full frame mirrorless camera; handheld high-resolution mode expands creative possibilities

Design & Build Quality: A Professional Tool with a Purpose

The S1R II inherits the rugged, premium magnesium-alloy chassis of its predecessor but adds subtle refinements that make a real difference in long shooting sessions. The body feels reassuringly solid, weather-sealed against dust, splashes, and freezing temperatures down to -10 °C, ensuring reliability in the field.

The redesigned grip is deeper and more ergonomic, providing excellent balance even with large L-Mount lenses. Every control dial, button, and joystick feels tactile and purposeful—clearly designed for professionals who shoot for hours.

A high-resolution 9.44 million-dot OLED EVF and a 3.2-inch tri-axis touchscreen complete the experience, allowing for precise framing and intuitive navigation whether shooting handheld, on a rig, or on a tripod.

This isn’t a flashy, fragile mirrorless—it’s a workhorse built to endure professional demands.

Sensor & Image Quality: Unrivaled Detail from a 44.3MP Full-Frame Sensor

At the heart of the LUMIX S1R II lies a brand-new 44.3-megapixel full-frame CMOS sensor, engineered to deliver staggering sharpness, tonal depth, and color accuracy. The result is professional-grade detail that remains consistent across all ISO ranges.

Sensor Type: 44.3 MP Full-Frame CMOS
Dynamic Range: 15 + stops (dual native ISO architecture)
Image Processor: Next-Gen Venus Engine X
Color Depth: 14-bit RAW output

The upgraded Venus Engine X introduces enhanced demosaicing algorithms that deliver more natural skin tones and finer color transitions. You’ll notice it immediately in portrait and landscape work—tones look organic, not over-processed.

For commercial and product photographers, the pixel-shift high-resolution mode pushes output beyond 180 MP, creating massive files that preserve microscopic texture and edge fidelity. It’s breathtaking.

8K Video Capability: Cinema Power in a Mirrorless Body

Panasonic’s video pedigree shines brightest here. The S1R II is LUMIX’s first camera capable of 8K recording, making it one of the most versatile hybrid tools of 2025.

Video Resolutions: 8K 30p, 6K 60p, 4K 120p 10-bit 4:2:2
Recording Limit: Unlimited in all modes (when externally powered)
Codec Support: H.265 HEVC / ProRes via HDMI RAW output
Color Profile: V-Log / V-Gamut (14+ stops dynamic range)

Whether you’re filming a short film, a music video, or commercial content, the 8K capture gives immense post-production flexibility. You can crop, reframe, or pull 4K stills—all from a single 8K timeline.

Combined with Dual I.S. 3 5-axis stabilization, the S1R II produces unbelievably smooth handheld footage that looks like it came off a gimbal. Panasonic’s hybrid autofocus system, now powered by AI-based subject recognition, finally brings fast, reliable tracking of humans, animals, and vehicles.

Autofocus & Stabilization: Sharper, Smarter, and Smoother

Autofocus has long been Panasonic’s Achilles heel—but not anymore. The S1R II introduces an AI-driven Hybrid Phase Detection AF System with 779 focus points and lightning-fast subject acquisition.

It can now detect human eyes, heads, animals, birds, and even vehicles, dynamically adjusting focus in real time. Continuous AF performance during 8K video or burst shooting is among the best Panasonic has ever achieved.

Meanwhile, the updated Dual I.S. 3 stabilization combines in-body 5-axis IBIS and lens-based 2-axis OIS for up to 8 stops of shake compensation—incredible for handheld telephoto or macro work.

Even when shooting at night or in low light, images remain razor-sharp with almost no motion blur.

Low-Light & Dynamic Range Performance

Thanks to its dual native ISO architecture, the S1R II produces exceptionally clean images in low light, maintaining tonal integrity up to ISO 25,600. Highlights roll off smoothly, and shadows retain depth—something you can’t always say about other high-resolution sensors.

Combined with V-Log, you get a true 14+ stops of usable dynamic range, matching cinema-grade cameras in flexibility. Whether shooting astrophotography, weddings, or studio portraits, you can push files in post without banding or color shifts.

Ergonomics & User Experience: Crafted for Professionals

Every inch of the S1R II is engineered for real-world usability. The menu system remains classic LUMIX—deep, but logically organized. Custom buttons let you store shooting presets for quick swaps between stills and video setups.

The dual card slots (CFexpress Type B + UHS-II SD) allow redundancy for professional workflows, while full-size HDMI, USB-C 3.2, and headphone/mic ports ensure robust connectivity on set.

Battery performance has improved by about 20% over the previous generation, and USB-PD charging means you can top up via power bank—essential for travel photographers and filmmakers.

Connectivity & Smart Features

Bluetooth 5.3 & Dual-Band Wi-Fi 6: Instant wireless transfer and tethered control.
LUMIX Sync App: Remote shooting, file browsing, and live preview from smartphone.
Tethered USB Streaming: Ideal for studio or live-production environments.
Custom LUT Import: Load your own color grading profiles directly in-camera.

Panasonic clearly understands how professionals work in 2025—fast, connected, and often mobile. The S1R II integrates seamlessly into any hybrid workflow.

Real-World Performance: Professional Results Every Time

During real-world testing, the S1R II proved incredibly versatile. It delivers stunning 44 MP RAW files with lifelike texture and color accuracy, and 8K footage that rivals dedicated cinema cameras.

The rolling-shutter performance has been improved, the autofocus tracking is finally competitive, and thermal management is rock solid—even during hour-long 8K recordings.

Simply put, it’s a no-compromise tool for photographers and filmmakers who demand precision, speed, and reliability.
