Check Shutter Count →The Sony A7R (ILCE-7R, 2013) was Sony's first high-resolution full-frame mirrorless camera and a pioneer of the E-mount system. It features a 36.4 MP full-frame Exmor CMOS sensor (without an optical low-pass filter for maximum sharpness), magnesium alloy body, and Sony's FE lens mount. The A7R uses a mechanical shutter rated for approximately 100,000 actuations.
| Spec | Sony A7R | Sony A7R II | Sony A7 |
|---|---|---|---|
| Sensor | 36.4 MP Exmor CMOS | 42.4 MP Exmor R BSI-CMOS | 24.3 MP Exmor CMOS |
| Rated shutter life | 100,000 | 500,000 | 100,000 |
| Release year | 2013 | 2015 | 2013 |
| IBIS | No | 5-axis | No |
| Max video | 1080p 60fps | 4K 30fps | 1080p 60fps |
The A7R uses Sony's cubic residue encryption on tag 0x9050 with byte offset 0x0032 (same as A7 and A7 II). ShutterCount handles the decryption automatically.
| Shutter Count | Assessment |
|---|---|
| 0 – 10,000 | Very low — barely used |
| 10,000 – 30,000 | Low to moderate — plenty of life left |
| 30,000 – 60,000 | Moderate to high |
| 60,000 – 100,000 | High — approaching rated life |
| 100,000 + | Beyond rated life — shutter failure risk increases |
The Sony A7R encrypts the shutter count in ARW MakerNote tag 0x9050 using Sony's cubic residue algorithm (modulo 249). After decryption, ShutterCount reads the count at byte offset 0x0032 — the same offset used by the original A7 and A7 II. All processing happens in your browser.
Take an ARW still photo and drop it into shuttercount.app. The encrypted count is decrypted from tag 0x9050 in your browser, instantly and privately.
The A7R is rated for approximately 100,000 mechanical shutter actuations. The A7R II dramatically increased this to 500,000.
Yes. The A7R II added 5-axis IBIS, a back-illuminated sensor with better high-ISO performance, dramatically improved AF, 4K video, and a 5x higher shutter rating (500,000 vs 100,000). It's one of the most significant generational upgrades in Sony's lineup.
The original A7R does not have a silent/electronic shutter mode. This feature was introduced with later Sony bodies. The shutter count reflects all mechanical shutter actuations.
