Drop an ARW RAW file from your Sony Cyber-shot RX10 III (DSC-RX10M3) and get the exact shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Sony Cyber-shot DSC-RX10M3 (2016) is the third generation of Sony's premium 1-inch sensor all-in-one bridge camera, and arguably the model that defined the category. Its 24–600 mm equivalent Zeiss Vario-Sonnar T* zoom lens (f/2.4–4.0), paired with the stacked 20.1 MP 1-inch CMOS sensor, delivers image quality and reach previously impossible in a single camera. The mechanical shutter supports up to 14 fps burst shooting.
| Model | Release | Sensor | Est. Shutter Life | RAW Format | EXIF Tag |
|---|---|---|---|---|---|
| Sony RX10 III (DSC-RX10M3) | 2016 | 20.1 MP 1-inch stacked CMOS | ~200,000 | ARW | 0x9050 |
| Sony RX10 IV (DSC-RX10M4) | 2017 | 20.1 MP 1-inch stacked CMOS | ~200,000 | ARW | 0x9050 |
| Sony RX100 VII (DSC-RX100M7) | 2019 | 20.1 MP 1-inch stacked CMOS | ~200,000 | ARW | 0x9050 |
The Sony RX10 III does not show the shutter count in its on-camera menu. The count is stored in the encrypted MakerNote tag 0x9050 in every ARW RAW file.
Processing runs entirely on your device. The ARW file is never sent to any server.
| Actuations | % of Est. Life | Assessment |
|---|---|---|
| 0 – 10,000 | 0 – 5 % | Very low use — near new |
| 10,000 – 50,000 | 5 – 25 % | Low use — plenty of life remaining |
| 50,000 – 120,000 | 25 – 60 % | Moderate use — acceptable for an active wildlife or event camera |
| 120,000 – 170,000 | 60 – 85 % | High use — negotiate price accordingly |
| 170,000 + | 85 %+ | Near or past estimated life — budget for shutter service |
The RX10 III is commonly used in burst mode for wildlife and sports, so expect higher counts than on a typical enthusiast camera. A high-count body used primarily for video may still have a healthy mechanical shutter, since video recording does not increment the counter.
The Sony RX10 III stores its shutter count in the ARW file's encrypted MakerNote tag 0x9050 — the same tag used across Sony's full Alpha and Cyber-shot lineup. ShutterCount applies Sony's decryption algorithm (based on cubic residues modulo 249) and reads the count from the decrypted block.
All processing happens entirely in your browser. The ARW file never leaves your device.
Sony frequently strips the MakerNote from in-camera JPEGs, removing the shutter count. For reliable results, always use an ARW RAW file. Enable RAW or RAW+JPEG shooting in the camera's Image Quality menu before taking the test shot.
The RX10 III and RX10 IV share the same 24–600 mm f/2.4–4.0 Zeiss zoom lens and the same 20.1 MP 1-inch stacked CMOS sensor. The key upgrade in the RX10 IV is phase-detection AF for faster, more reliable subject tracking — and a higher burst rate of 24 fps. Both models produce ARW files with shutter count readable via tag 0x9050.
The RX10 III often sells at a significant discount compared to the RX10 IV. If phase-detection AF is not critical for your use case (landscape, travel, documentary), the RX10 III with a verified low shutter count offers outstanding value. For wildlife and sports photographers, the RX10 IV's phase-detection AF is a material advantage.
Shoot an ARW file with your RX10 III, then drop it into shuttercount.app. The count is decrypted from tag 0x9050 entirely in your browser — no upload needed.
No. Video recording on the RX10 III keeps the shutter open throughout the clip and does not increment the mechanical counter. Only still-image captures with the mechanical shutter add to the count. Bodies used primarily for video can have very low mechanical actuations despite heavy overall use.
Only a Sony authorised service centre can reset the hardware counter after a physical shutter replacement. EXIF-editing tools can modify file metadata but cannot alter the in-camera counter. Always verify from an original, unmodified ARW file.
