Check Shutter Count →The Sony A6400 is Sony's 2019 mid-range APS-C mirrorless camera — one of the best-selling mirrorless cameras of its generation. With a 24.2 MP Exmor CMOS sensor, real-time Eye AF, 11 fps burst, 4K video, and a flip-up screen for vlogging, the A6400 became the go-to camera for enthusiasts and content creators. Its 200,000-actuation shutter rating matches the higher-end A6600.

| 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 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 A6400 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 0x003a — the same offset used by the A6100, A6300, A6500, and A6600.
All processing happens locally in your browser. The ARW file is never transmitted anywhere.
Shoot an ARW file, then drop it into shuttercount.app. The count is decrypted from tag 0x9050 at offset 0x003a in your browser.
Sony rates the A6400 at 200,000 actuations — the same as the A6600 and the newer A6700.
The A6700 brings a stacked sensor, AI AF, and improved video. But a used A6400 with a low shutter count costs a fraction of a new A6700 and still delivers excellent photos with real-time Eye AF. For stills-focused work on a budget, the A6400 remains an outstanding choice.
Only a Sony authorised service centre can reset the hardware counter. Always verify from an original ARW file, not a screenshot.
