Canon shutter count: model support and CR3 limitations

Some Canon originals contain a readable ShutterCount. Support depends on the camera and parser. For example, ExifTool documents EOS R5/R6 and R6 Mark II counters that include both electronic and mechanical exposures.

Documented examples, not a universal compatibility list

ExifTool lists ShutterCount in CameraInfoR6 for EOS R5/R6 and CameraInfoR6m2 for EOS R6 Mark II. Its notes identify both as combined electronic-plus-mechanical counts. These are documented decoder fields, not cameras tested by ExifGrabber.

Read a Canon original

Use the original CR3 or JPEG. Preserve the full output and any warnings. If a browser viewer returns only general EXIF, use a dedicated MakerNote decoder before concluding that the counter is absent.

Why an old tool can miss an R6 count

The ExifTool author confirmed adding the reported R6 counter to version 12.68. This illustrates why a blanket claim that Canon files never contain a counter becomes outdated. Record your installed version when sharing results.

Does the number measure mechanical wear?

A combined counter cannot isolate mechanical actuations. For example, an illustrative total of 30,000 exposures could include extensive electronic-shutter use; the total alone cannot tell you the mechanical portion.

Do not rename FileNumber or FileIndex to ShutterCount in a report. If no documented field is available, say the file did not provide a supported count. A camera-compatible diagnostic or service inspection may be needed to answer a different question about the hardware.
