SONY A7M5 Shutter Count #369
Description
Exiftool 13.43 may read incorrect ShutterCount on Sony A7M5 (ILCE-7M5).
I took a 4-shot burst of ARW files from DPReview and ran exiftool -v5 on them. Here's what came up:
DSC09105.ARW
| | | | ShutterCount = 699
| | | | - Tag 0x0032 (4 bytes, int32u[1]):
| | | | a89c: bb 02 00 00 [....]
DSC09106.ARW
| | | | ShutterCount = 699
| | | | - Tag 0x0032 (4 bytes, int32u[1]):
| | | | a89c: bb 02 00 00 [....]
DSC09107.ARW
| | | | ShutterCount = 699
| | | | - Tag 0x0032 (4 bytes, int32u[1]):
| | | | a89c: bb 02 00 00 [....]
DSC09108.ARW
| | | | ShutterCount = 699
| | | | - Tag 0x0032 (4 bytes, int32u[1]):
| | | | a89c: bb 02 00 00 [....]
Tag 0x0032 at offset a89c is stuck at bb 02 00 00 (which is 699) for all four shots.
On Sony A7M5, the actual mechanical/electronic shutter count is most likely stored in MakerNote Tag 0x9050a, offset 0xa86a, bytes 11–14 (int32u little-endian), instead of the current Tag 0x0032.
Here are those bytes:
DSC09105.ARW
a86a: 00 00 00 00 00 00 00 00 00 00 38 02 00 00 00 00 [..........8.....]
DSC09106.ARW
a86a: 00 00 00 00 00 00 00 00 00 00 39 02 00 00 00 00 [..........9.....]
DSC09107.ARW
a86a: 00 00 00 00 00 00 00 00 00 00 3a 02 00 00 00 00 [..........:.....]
DSC09108.ARW
a86a: 00 00 00 00 00 00 00 00 00 00 3b 02 00 00 00 00 [..........;.....]
These give 568, 569, 570, 571.
