Drop an ARW RAW file from your Sony Alpha 580 and get the shutter actuation count in seconds — processed entirely in your browser. The DSLR-A580 stores its shutter count in unencrypted MakerNote block 0x0020 (MoreInfo block 0x0201, offset 0x0125).
Check Shutter Count →The Sony Alpha 580 (DSLR-A580, November 2010) was the last consumer A-mount camera Sony released using a traditional optical viewfinder and conventional mirror mechanism — making it the final chapter of Sony's DSLR era before the SLT transition. It featured a 16.2 MP APS-C Exmor CMOS sensor, BIONZ processor, 7 fps burst, and 1080i video recording. Its 16.2 MP sensor was the highest resolution in the consumer A-mount DSLR lineup and represented a direct response to Canon's 18 MP 550D and Nikon's 16.2 MP D7000.
Sony rates the Alpha 580 mechanical shutter at 100,000 actuations.
| Model | Release | Sensor | Rated Shutter Life | RAW Format |
|---|---|---|---|---|
| Sony Alpha 580 (DSLR-A580) | 2010 | 16.2 MP APS-C Exmor CMOS | 100,000 actuations | ARW |
| Sony Alpha 550 (DSLR-A550) (prev. enthusiast) | 2009 | 14.2 MP APS-C Exmor CMOS | 100,000 actuations | ARW |
| Sony SLT-A55 (concurrent SLT) | 2010 | 16.2 MP APS-C Exmor CMOS | ~100,000 actuations | ARW |
| Actuation Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 10,000 | 0 – 10 % | Very low use — near new |
| 10,000 – 40,000 | 10 – 40 % | Low to moderate use |
| 40,000 – 75,000 | 40 – 75 % | Moderate to heavy use |
| 75,000 – 95,000 | 75 – 95 % | High use — negotiate price |
| 95,000 + | 95 %+ | Near or past rated life |
The A580 remains a capable 16 MP Exmor body with full A-mount compatibility and in-body IBIS. On the used market it offers excellent value for A-mount lens owners. Always check shutter count — 7 fps burst users may have accumulated high counts quickly.
The Alpha 580 uses unencrypted Sony MakerNote block 0x0020 (MoreInfo block 0x0201, offset 0x0125) for the shutter count — the layout ExifTool documents for this body. ShutterCount parses the ARW TIFF structure, locates this block, and reads the counter directly. The A580 is one of the last Sony A-mount cameras to use this straightforward unencrypted approach; the SLT cameras that launched alongside it (A55, A33) use the same plain MoreInfo block; the encrypted 0x9050 tag came with later bodies such as the SLT-A65/A77.
Both cameras share the same 16.2 MP Exmor sensor and BIONZ processor. The key difference is the viewfinder: the A580 uses a conventional optical viewfinder with a flip mirror, while the A55 uses Sony's SLT (Single Lens Translucent) technology with a fixed translucent mirror and electronic viewfinder. The A55 offers 10 fps burst vs 7 fps on the A580, but the A580 provides a traditional optical shooting experience. Their shutter counts are stored the same way: A580 uses unencrypted MakerNote block 0x0020 (MoreInfo block 0x0201, offset 0x0125); the A55 uses the same block and offset.
The A580 records 1080i video using a continuous readout without operating the mechanical shutter. Only still photo exposures increment the shutter counter. Video recording has no impact on the shutter count.
