Drop an ARW RAW file from your Sony RX10 II (DSC-RX10M2, 2015) and get the exact shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Sony RX10 II (DSC-RX10M2, 2015) was the first camera in the RX10 line to use a stacked BSI CMOS sensor, unlocking capabilities far beyond its predecessor. It shares the constant f/2.8 Zeiss Vario-Sonnar T* 24–200 mm lens with the original RX10 but gains 4K/30p video, 960/480/240 fps super slow-motion in 1080p, up to 16 fps burst shooting, and a significantly improved XAVC S video codec. These additions made the RX10 II a compelling tool for filmmakers and action-content creators needing high-speed capture in a compact body.
Sony does not publish an official rated shutter life for the RX10 II. Based on community data, the compact mechanism is estimated at approximately 200,000 actuations. The shutter count is stored encrypted in MakerNote tag 0x9050 of every ARW RAW file.
| Model | Release | Sensor | Est. Shutter Life | RAW Format |
|---|---|---|---|---|
| Sony RX10 II (DSC-RX10M2) | 2015 | 20.1 MP 1-inch stacked BSI | ~200,000 (est.) | ARW |
| Sony RX10 (Mark I) | 2013 | 20.1 MP 1-inch BSI CMOS | ~200,000 (est.) | ARW |
| Sony RX10 IV (24–600 mm) | 2017 | 20.1 MP 1-inch stacked BSI | ~200,000 (est.) | ARW |
The Sony RX10 II stores the shutter count encrypted in MakerNote tag 0x9050 of every ARW RAW file. ShutterCount decrypts and reads it automatically.
RX10 II bodies are often purchased specifically for slow-motion and video work. Since video does not increment the mechanical counter, stills counts on video-oriented bodies are frequently very low — a sub-5,000 count on a video-heavy body is completely normal and does not indicate the camera is barely used overall. Ask specifically about total video recording hours when buying from a videographer.
| Actuation Count | % of Est. Life | Assessment |
|---|---|---|
| 0 – 10,000 | 0 – 5 % | Very low — near new or video-primary use |
| 10,000 – 40,000 | 5 – 20 % | Low use — plenty of life remaining |
| 40,000 – 100,000 | 20 – 50 % | Moderate use — normal for a stills shooter |
| 100,000 – 160,000 | 50 – 80 % | High use — negotiate price |
| 160,000 + | 80 %+ | Heavy use — budget for potential shutter service |
Sony stores the shutter count in ARW files in encrypted form within MakerNote tag 0x9050. The encryption uses a cubic residue cipher modulo 249: each byte is cubed modulo 249 to produce the decrypted value, using a per-model key derived from the first bytes of the tag.
This same encrypted structure applies across the full Sony ARW lineup. After decryption, ShutterCount reads the 32-bit count from the appropriate byte offset within the decrypted block.
At 240–1000 fps the RX10 II captures slow-motion footage using sensor readout only — the mechanical shutter is open and stationary during these captures. Slow-motion clips do not increment the mechanical shutter counter, so even intensive slow-motion use leaves no trace in the shutter count.
Shoot one ARW RAW file, then drop it into shuttercount.app. The tool decrypts and reads the shutter count from MakerNote tag 0x9050 entirely in your browser.
Sony does not publish an official shutter rating for the RX10 II. Community estimates suggest approximately 200,000 actuations. This is an informal estimate, not a Sony specification.
Yes — the RX10 II remains an excellent slow-motion and hybrid photo/video tool. Key things to check beyond shutter count: video output quality (look for banding or moire), slow-motion clip quality at all speeds, zoom mechanism smoothness, and internal microphone/audio jack function.
The RX10 III (2016) extended the zoom range from 24–200 mm to 24–600 mm equivalent, opening up wildlife and sports photography as use cases. The lens speed reduces to f/4.0 at the long end. The RX10 II's constant f/2.8 aperture gives it a consistent light advantage for events and concerts but at the cost of the extra reach.
