Drop an ARW RAW file from your Sony A1 II (ILCE-1M2) and get the exact shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Sony A1 II is the second generation of Sony's ultimate flagship mirrorless camera. It combines a 50.1 MP stacked Exmor RS CMOS sensor with 30 fps blackout-free shooting, 8K video, and AI-driven autofocus. The mechanical shutter is rated at 500,000 actuations, making it one of the most durable mirrorless shutters available.
| Model | Release | Sensor | Rated Shutter Life | RAW Format |
|---|---|---|---|---|
| Sony A1 II (ILCE-1M2) | 2024 | 50.1 MP stacked full-frame | 500,000 | ARW |
| Sony A1 (ILCE-1) | 2021 | 50.1 MP stacked full-frame | 500,000 | ARW |
| Sony A9 III (ILCE-9M3) | 2024 | 24.6 MP global shutter | No mechanical shutter | ARW |
Sony does not display the shutter count in the camera menus. The count is embedded in the encrypted MakerNote of every ARW RAW file.
The tool handles the Sony encryption automatically — you just need an original ARW file.
With a 500,000-actuation rating, the A1 II is built for professional high-volume shooting.
| Actuation Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 50,000 | 0 – 10 % | Very low use — near new |
| 50,000 – 150,000 | 10 – 30 % | Low use — plenty of life remaining |
| 150,000 – 300,000 | 30 – 60 % | Moderate use — normal for professionals |
| 300,000 – 450,000 | 60 – 90 % | High use — negotiate price accordingly |
| 450,000 + | 90 %+ | Near or past rated life — budget for shutter replacement |
Sony ARW files store the shutter count in MakerNote EXIF tag 0x9050, which is encrypted using a cubic residue cipher modulo 249. ShutterCount decrypts this tag in your browser, then reads the shutter count as a uint32 little-endian value at byte offset 0x000a.
This offset (0x000a) is shared with the Sony A7R V, A6700, and A7CR generation. It differs from the original A1's offset of 0x003a. ShutterCount detects the camera model from the ARW metadata and applies the correct offset automatically.
No. The A1 II's electronic shutter reads the stacked sensor without engaging the mechanical curtain. Those frames do not increment the shutter count. Only mechanical shutter exposures are counted.
Shoot an ARW RAW file and drop it into shuttercount.app. The encrypted shutter count is decrypted and displayed in your browser — no upload needed.
Sony rates the A1 II at 500,000 mechanical actuations, the same as the original A1.
The hardware counter is managed by the camera's firmware and cannot be reset by users. EXIF-editing tools can modify file metadata but cannot change the encrypted in-camera counter. Always verify from an original, unedited ARW file.
The A1 II adds AI-based autofocus with improved subject recognition, 8.5-stop IBIS (up from 5.5), improved grip ergonomics, and enhanced connectivity. The 50.1 MP stacked sensor is carried over. The encrypted shutter count offset changed from 0x003a to 0x000a.
