| Predecessor | Panasonic LUMIX DC-S1R |
The Panasonic LUMIX S1RII (also known as the LUMIX DC-S1RII) is a digital, full frame mirrorless camera released by Panasonic in 2025 as part of the LUMIX S series.[1] It is the successor to the LUMIX S1R that was released in 2019.[2] The LUMIX S1RII introduced faster phase-detect autofocus and improved 8K video capabilities.[3] It also improved stabilization, and also has a smaller and lighter body than its predecessor. The camera debuted a 44.3 MP back-side illuminated CMOS sensor. This camera is designed as a hybrid model that has a wide range of features for both still photography and video production.[2]
Features
Image sensor
The S1RII debuted a 44.3-megapixel back-side illuminated CMOS sensor[2] with dual conversion gain that allows you to manually select which readout mode you prefer. The sensor is faster, but with slightly lower resolution than the S1R. The sensor’s readout time is approximately 1/27 sec in 14-bit mode and 1/50 sec in the 12-bit mode used for bursts and other quick-fire shooting modes. This sensor offers 8.1K footage (8128x4288) which conforms to the 1.89:1 aspect ratio found in DCI footage.[1] The non-stacked sensor provides a dynamic range advantage over some contemporary competitors.[4] The camera also improved processing from its L2 Engine.[3]
The camera also has a carbon fiber shutter mechanism that shields the sensor when changing lenses.[4]
In June 2026, Panasonic also introduced focus stacking, allowing the synthesis of images taken at multiple focus positions.[5]
Video capabilities
The S1RII has an extensive video features set that expands greatly on the options of the S1R. Some features include various exposure settings and monitoring tools like waveforms and vectorscopes displays, custom lists for video modes, and a tally lamp to signify recording.[1]
The camera also offers many options for resolutions and aspect ratios and frame rates.[1] New for this model, Panasonic added 8K recording at up to 30 fps. The LUMIX S1RII can also capture 5.8K Apple ProRes RAW HQ or ProRes RAW without an external recorder.[2] In addition to standard MOV compression, the S1RII supports ProRes 422 and ProRes RAW recording at various resolutions, which can be saved internally to a CFexpress Type B card or externally to an SSD.[1]
The S1RII includes a DR Expansion mode that provides an additional stop of highlight detail in high-contrast scenes when recording V-Log video at up to 30p.[4] It uses a higher bit-depth readout and raises the minimum available ISO.[1]
Like many LUMIX cameras, the S1RII also provides Open Gate recording captured at 6.4K in a 3:2 aspect ratio which allows for the capture of the full area of the sensor and lets you adjust crop during post production. It also has the ability to capture a 4:3 region of the sensor.[1]
The S1RII records Full HD (1920 × 1080) using the same frame rates and crop options as its UHD 4K modes, with additional support for 100 fps and 120 fps recording from an APS-C crop.[1]
For audio, the camera can record 4-channel 32-bit float audio and is compatible with the DMW-XLR2 adapter.[4] The S1RII also integrates with the LUMIX DMS1 microphone launched in February 2026 via the camera’s hotshoe to improve audio quality without extra cables.[6]
In a firmware update in November 2025, Panasonic improved thermal control adjustments allowing the S1RII to have longer video record times of up to 50 minutes that are less affected by environmental factors. The update also added options to the autofocus interface, added a 20 fps option to Super High-Speed (SH) burst mode, and added a new MP4(Lite) low bitrate format of 3.8K open gate at 50 Mbps, among other minor changes.[7]
Still photography features
For photography, the S1RII can capture full-resolution 12-bit RAW still images at up to 40 fps using its electronic shutter, or up to 10 frames per second using its mechanical shutter’s "High Speed Plus" mode. It also offers a handheld high-resolution mode that can capture still images at 177-megapixels by shifting the sensor half a pixel and capturing and merging multiple exposures.[2] It also has standard Panasonic features like the Live-View Composite mode and multiple exposures.[8] Combined with its autofocus support, this is ideal for sports and wildlife photography.[3]
Autofocus
The S1RII marks a change from the S1R which relied only on contrast-based autofocus. The S1RII uses a system which combines the contrast-based algorithms with phase detection AF that improves tracking accuracy for moving subjects.[2] The S1RII has 779 selectable AF points on the frame. Subject recognition was trained on humans, animals, cars, motorcycles and bikes, trains, and airplanes.[3] The autofocus allows the user to choose specific details to lock on to, but choosing a more precise focus point can reduce responsiveness.[1]
In a firmware update from June 2025, Panasonic added an Urban Sports detection mode for fast, dynamic subjects. The update also added 10 AF frame colors for better visibility under any conditions.[5]
Body
The body of the S1RII is smaller and lighter than its predecessor the S1R and weighs only 1.75 pounds[2] and measures 134×102×92mm.[3] It has a magnesium alloy frame and is weather-sealed to provide dust and splash resistance. It can also operate in temperatures ranging from -10 °C to 40 °C.[9] It includes an internal fan with two exhaust ports to the sides of its viewfinder.[1] Dual memory card slots include one CFexpress Type B slot and one SD (UHS‑II) slot, and the camera also includes a full-sized HDMI port.[2]
The S1RII also features a high‑resolution OLED electronic viewfinder with 5.76‑million dots. The LCD display is a three-inch articulating 1.84-million dot touchscreen that can flip and rotate for videographers.[2]
It introduced a new three-way selector switch to choose between photo, video,and S&Q (Slow & Quick) modes that saves preferences and customizations for each mode. A locking switch ensures settings don’t reset spontaneously.[4]
The S1RII uses the 15.8Wh DMW-BLK22 battery and launched the DMW-BG2 battery grip. Chargeable by USB-C, the battery is CIPA-rated to provide 350 shots when using the LCD. The battery grip essentially doubles the battery life by adding support for a second battery with hot-swapping functionality and the option to use both batteries simultaneously.[1]
Lenses
The S1RII is compatible with Leica L-Mount lenses. Like other LUMIX S bodies, this includes a wide range of lenses from Panasonic, Sigma, Leica and more.[3]
It also has support for anamorphic lenses.[1]
In-body image stabilization
The S1RII has a built-in IBIS unit with up to eight stops of stability, or seven stops when using it with a telephoto lens with stabilization.[2] The system offers multiple stabilization settings including a “Boost” mode that prioritizes steadiness by correcting all camera movement.[1] It also debuted a handheld image stacking feature that allows for 177-megapixel files without needing a tripod.[4] Stabilization is best in class on this camera.[1]
Connectivity and smart features
The S1RII has dual memory card slots for CFexpress Type B and SD (UHS‑II) cards and ports for a full-size HDMI cable as well as a 10Gbps USB-C port which can be used to send videos to an external SSD.[2] It also has a microphone and headphone jack.[1]
Alongside the S1RII, Panasonic launched their LUMIX Flow app to help with video production, and allows you to use your phone as a video monitor while it is attached to the camera via USB-C.[4] The S1RII also integrates with third-party software. It was the first Panasonic camera that can be shot and tethered from Capture One software, and it also integrates with software like Frame.io. It has Wi-Fi 5 and Bluetooth v5.0 connectivity.[3]
Assist tools
For video, features include assist tools including Waveforms, Vectorscopes, and False Color.[1]
While common in video cameras, the S1RII is one of the first hybrid cameras to include a false color display option. Another new feature is the "Cinelike A2" color mode for stills and video modes. Like some other Panasonic cameras, the S1RII also has a Real Time Look Up Table (LUT) which lets you create color and tone-modifying profiles. The S1RII allows for 39 LUTs which can be created or downloaded via Panasonic’s LUMIX lab app.[1]
Optional support for various color profiles, with ARRI LogC were added in a firmware update in June 2025.[5]
Similar cameras
The S1RII’s smaller and lighter body is similar to the S5II series making it 20% smaller and lighter than the S1R.[4] It also shares the internal fan from the S5II, with two exhaust ports to the sides of its viewfinder.[1]
The S1RII has the same 15.8Wh DMW-BLK22 battery as the LUMIX S5II, S5IIX, S9, S1II and S1IIE.[1]
The Canon EOS R5 Mark II and the Nikon Z8 are the S1RII's main competitors.[1][4]
Reception
Reviewers have highlighted the S1RII’s faster phase-detect autofocus and improved stabilization on a smaller and lighter body.[2][3] Many appreciated the excellent image quality, comfortable handling, and the dependable video recording for lengthy shooting due to the built-in fan.[1][4] Others noted the versatility of the camera because of the L-mount system.[3] The Verge recommended the S1RII for "shooters looking for a highly capable hybrid camera."[2]
Some reviewers mentioned that though the S1RII has competitive specs among its competitors, it trades some of the speed of similar cameras for a lower price point.[1][4] Video autofocus has also been described as capable but not class-leading.[1]
