Drop an ARW RAW file from your Sony RX10 (DSC-RX10, Mark I, 2013) and get the exact shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Sony RX10 (DSC-RX10, 2013) was Sony's first large-sensor bridge camera and set a new benchmark for the genre. It features a 20.1 MP 1-inch BSI CMOS Exmor R sensor, a Zeiss Vario-Sonnar T* 8.8–73.3 mm f/2.8 lens (24–200 mm equivalent) with constant f/2.8 maximum aperture throughout the entire zoom range, 1080/60p video, and a built-in ND filter. The constant f/2.8 aperture set it apart from all other bridge cameras and made it a favourite among travel, event, and documentary photographers who needed versatility without carrying a system camera.
Sony does not publish an official rated shutter life for the RX10. 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 (DSC-RX10) | 2013 | 20.1 MP 1-inch BSI CMOS | ~200,000 (est.) | ARW |
| Sony RX10 II (stacked sensor) | 2015 | 20.1 MP 1-inch stacked BSI | ~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 stores the shutter count encrypted in MakerNote tag 0x9050 of every ARW RAW file. ShutterCount decrypts and reads it automatically.
The RX10 Mark I was popular with travel and event photographers but saw less burst-heavy use than the wildlife-focused III and IV. Many used copies have moderate counts. Given the camera's age (released 2013), also check for lens barrel wear, zoom mechanism smoothness, and display condition.
| Actuation Count | % of Est. Life | Assessment |
|---|---|---|
| 0 – 10,000 | 0 – 5 % | Very low use — near new |
| 10,000 – 40,000 | 5 – 20 % | Low use — plenty of life remaining |
| 40,000 – 100,000 | 20 – 50 % | Moderate use — normal for an active 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 — from the A1 flagship down to the RX10 compact. After decryption, ShutterCount reads the 32-bit count from the appropriate byte offset within the decrypted block.
No. The RX10's built-in 3-stop ND filter controls exposure by reducing incoming light, not by altering the shutter mechanism. All exposures — with or without ND — actuate the mechanical shutter the same way.
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 Mark I. Community estimates suggest approximately 200,000 actuations. This is an informal estimate, not a Sony specification.
Yes — the constant f/2.8 aperture across the 24–200 mm range remains impressive for event, concert, and travel photography. Key things to check beyond shutter count: zoom ring and barrel for mechanical wear, video autofocus performance (contrast-detect only, slowish for video), lens for fungus or delamination, and battery condition.
The RX10 II (2015) added a stacked CMOS sensor enabling 1000 fps super slow-motion video, a higher burst rate (16 fps vs 12 fps), and 4K video. The lens and field of view (24–200 mm f/2.8) are identical. If 4K video or slow-motion are priorities, the II is worth the extra cost on the used market.
