Drop a CR3 RAW file from your Canon EOS R6 Mark III and get the shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Canon EOS R6 Mark III is Canon's latest mid-range full-frame mirrorless camera, building on the hugely successful R6 and R6 Mark II line. It targets wedding, event, and portrait photographers who need a fast, versatile body with excellent autofocus and high ISO performance.
| Model | Release | Sensor | Shutter Count Field | RAW Format |
|---|---|---|---|---|
| Canon EOS R6 Mark III | 2025 | 24.2 MP full-frame | ImageCount (0x086D) | CR3 |
| Canon EOS R6 Mark II | 2022 | 24.2 MP full-frame | Offset 0x0D29 | CR3 |
| Canon EOS R6 | 2020 | 20.1 MP full-frame | Offset 0x0AF1 | CR3 |
The R6 Mark III does not show the image count in its on-screen menus. The counter is embedded in every CR3 RAW file.
For the most accurate count, use a file shot before formatting the card, as formatting may reset the ImageCount field.
While Canon has not published an official shutter rating for the R6 Mark III, the R6 II was rated at 300,000 actuations. Use similar thresholds as a guideline.
| Image Count | Assessment |
|---|---|
| 0 – 30,000 | Very low use — near new |
| 30,000 – 65,000 | Low use — uint16 max is 65,535 |
The ImageCount field is a uint16 value (max 65,535). For cameras with very high usage, the counter may have wrapped. Cross-reference with the camera's overall condition and service history.
The R6 Mark III writes images in Canon's CR3 format. ShutterCount parses the ISOBMFF box hierarchy to find the EXIF MakerNote and reads the ImageCount field at byte offset 0x086D as a uint16 little-endian value.
This is the same offset and field type used by the Canon EOS R1 and R50 V. It differs from the uint32 offsets used by the R5 Mark II (0x069C) and R6 Mark II (0x0D29).
No. The R6 Mark III's electronic shutter does not engage the mechanical curtain and does not increment the ImageCount.
Shoot a CR3 RAW file and drop it into shuttercount.app. The ImageCount is read from offset 0x086D in your browser — no upload needed.
The ImageCount field (uint16 at 0x086D) may reset when the camera is formatted. For the most reliable reading, check a file taken before formatting.
EXIF tools can modify metadata in a file copy but cannot change what the camera writes into future CR3 files. Always verify from an original, unedited file.
The R6 Mark II stores its shutter count as a uint32 at offset 0x0D29, while the R6 Mark III uses a uint16 ImageCount at 0x086D. The R6 III shares this new counter type with the R1 and R50 V.
ShutterCount supports the full Canon EOS R system. See related guides:
