Learn about the Panasonic Lumix S1 shutter lifespan, acceptable counts for used camera buying, and how to check the actuation count — Panasonic does not store the count in RW2 files, so the camera menu is the primary method.
Check Shutter Count →The Panasonic Lumix S1 (2019) was Panasonic's first full-frame L-mount mirrorless camera, co-developed with Leica and Sigma as part of the L-Mount Alliance. It pairs a 24.2 MP full-frame Dual Native ISO sensor with a professional-grade body featuring extensive weather sealing (IP53 equivalent), dual card slots (CFexpress B / SD), and a best-in-class 5-axis IBIS system rated at 6.5 stops. The mechanical shutter is rated at a remarkably high 400,000 actuations.
| Model | Release | Sensor | Rated Shutter Life | RAW Format |
|---|---|---|---|---|
| Panasonic Lumix S1 | 2019 | 24.2 MP full-frame | 400,000 | RW2 |
| Panasonic Lumix S1R | 2019 | 47.3 MP full-frame | 400,000 | RW2 |
| Panasonic Lumix S5 | 2020 | 24.2 MP full-frame | 200,000 | RW2 |
| Panasonic Lumix S5 II | 2023 | 24.2 MP full-frame | 200,000 | RW2 |
Connect your S1 to the Panasonic Lumix Sync smartphone app via Wi-Fi. The app displays the shutter count under the camera information section.
Some firmware versions embed a partial shutter count in RW2 EXIF data under PanasonicRaw:ShutterCount. You can try: exiftool -ShutterCount your_file.RW2 — however, Panasonic does not officially guarantee this value is always present or current.
With a 400,000-actuation rating, the S1 has significantly more headroom than most full-frame mirrorless cameras:
| Actuation Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 40,000 | 0 – 10 % | Very low use — near new |
| 40,000 – 120,000 | 10 – 30 % | Low use — plenty of life remaining |
| 120,000 – 240,000 | 30 – 60 % | Moderate use — normal for active shooters |
| 240,000 – 360,000 | 60 – 90 % | High use — negotiate price accordingly |
| 360,000 + | 90 %+ | Near or past rated life — factor in shutter replacement (~€150–250) |
The Panasonic Lumix S1 mechanical shutter is rated at 400,000 actuations — one of the highest ratings among full-frame mirrorless cameras and on par with professional DSLRs like the Nikon D6.
Panasonic does not consistently embed the mechanical shutter count in RW2 RAW files, unlike Canon (CR3), Nikon (NEF), Sony (ARW), and Fujifilm (RAF). The authoritative source is the camera's own menu counter.
The S1R uses a 47.3 MP sensor for maximum resolution, while the S1 uses 24.2 MP for better high-ISO performance and faster continuous shooting. Both share the same body, 400,000-actuation shutter, and weather sealing. The S1 received a firmware update adding 4K/60p and V-Log; the S1R also supports High Resolution Shot (96 MP composite).
