Check Shutter Count →The Sony A7C II is Sony's 2023 second-generation compact full-frame mirrorless camera, featuring the same 33 MP BSI sensor as the A7 IV in a significantly smaller rangefinder-style body. Released alongside the A7CR (61 MP), the A7C II targets travel, street, and hybrid photographers who want A7 IV image quality in a pocketable form factor. Despite its compact size, it carries a 200,000-actuation shutter rating — actually higher than the A7 IV.
| Model | Release | Sensor | Rated Shutter Life | Form Factor |
|---|---|---|---|---|
| Sony A7C II (ILCE-7CM2) | 2023 | 33 MP full-frame BSI | 200,000 | Compact rangefinder |
| Sony A7 IV (same sensor) | 2021 | 33 MP full-frame BSI | 150,000 | Traditional mirrorless |
| Sony A7CR (compact 61MP) | 2023 | 61 MP full-frame BSI | 200,000 | Compact rangefinder |
| Actuation Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 20,000 | 0 – 10 % | Very low use — near new |
| 20,000 – 60,000 | 10 – 30 % | Low use — plenty of life remaining |
| 60,000 – 120,000 | 30 – 60 % | Moderate use — normal for active travel photographers |
| 120,000 – 180,000 | 60 – 90 % | High use — negotiate price accordingly |
| 180,000 + | 90 %+ | Near or past rated life — budget for shutter service |
The Sony A7C II stores the shutter count encrypted in ARW MakerNote tag 0x9050. ShutterCount applies Sony's cubic residue decryption (modulo 249) and reads the count from byte offset 0x000a — the updated offset introduced with the 2023 Sony generation (A7C II, A7CR, A6700) compared to the 0x003a offset used by the 2021 generation (A7 IV, A7 III, A9 III, A1).
ShutterCount detects the camera model automatically from the ARW metadata and selects the correct offset. All processing is done locally in your browser.
Sony periodically updates its MakerNote internal structure when introducing new firmware platforms. The 2023 bodies (A7C II, A7CR, A6700) all use the newer layout. Tools that do not account for this change may read an incorrect count from an A7C II ARW — ShutterCount is calibrated for this.
Shoot an ARW file, then drop it into shuttercount.app. The count is decrypted from tag 0x9050 at offset 0x000a in your browser.
Sony rates the A7C II at 200,000 actuations — higher than the A7 IV (150,000) despite sharing the same sensor.
The A7 IV has a larger grip, dual SD slots, and a top LCD better suited to high-volume professional work. The A7C II is rated higher (200k vs 150k) but its compact body is optimised for travel and street, not marathon event shooting sessions.
Only a Sony authorised service centre can reset the hardware counter. Always verify from an original ARW file, not a screenshot.
