Drop an ARW RAW file from your Sony Alpha 390 and get the shutter actuation count in seconds — processed entirely in your browser. The DSLR-A390 stores its shutter count in unencrypted MakerNote tag 0x014a.
Check Shutter Count →The Sony Alpha 390 (DSLR-A390, June 2010) was Sony's entry-level A-mount DSLR for 2010, replacing the A380 with a notable sensor upgrade. Where the A380 used a CCD sensor, the A390 introduced a 14.2 MP APS-C Exmor CMOS sensor alongside a tilting 2.7-inch LCD — two significant improvements at the entry-level price point. The Exmor sensor delivered improved noise performance at high ISO, while the tilting LCD made live view composition from low or high angles practical. In-body Super SteadyShot IBIS remains standard, and the A390 accepts all A-mount lenses including legacy Minolta AF glass.
Sony rates the Alpha 390 mechanical shutter at 100,000 actuations.
| Model | Release | Sensor | Rated Shutter Life | RAW Format |
|---|---|---|---|---|
| Sony Alpha 390 (DSLR-A390) | 2010 | 14.2 MP APS-C Exmor CMOS | 100,000 actuations | ARW |
| Sony Alpha 380 (DSLR-A380) (predecessor, CCD) | 2009 | 14.2 MP APS-C CCD | 100,000 actuations | ARW |
| Sony Alpha 290 (DSLR-A290) (budget sibling) | 2010 | 14.2 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 |
As an entry-level camera, the A390 was primarily sold to hobbyist photographers who typically accumulate lower shutter counts. Bodies on the used market with moderate counts represent good value for A-mount lens owners who want a tilting-LCD camera with in-body stabilisation.
The Alpha 390 uses unencrypted Sony MakerNote tag 0x014a for the shutter count — the same tag used across the entire A100–A580 DSLR series. ShutterCount parses the ARW TIFF structure, locates this tag, and reads the counter directly. No cipher or decryption is needed.
Yes. The A390 supports live view shooting via its tilting 2.7-inch LCD. It uses contrast-detect autofocus in live view mode (unlike the A300/A350 which used a secondary sensor for phase-detect live view AF). Live view display does not increment the shutter counter; only still exposures do.
Yes. The A390 uses the Sony A-mount, which is mechanically and electronically compatible with Minolta AF (Maxxum / Dynax) lenses from 1985 onward. Super SteadyShot stabilisation works with all A-mount lenses, including legacy Minolta glass without stabilisation information embedded in the lens.
