Drop a CR3 RAW file from your Canon EOS R5 or R5 Mark II and get the exact shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Canon EOS R5 is Canon's flagship full-frame mirrorless camera, designed for professional photographers and videographers. Its 45 MP sensor and high-speed shooting make it a popular choice for wildlife, sports, and studio work — and also one of the most commonly traded second-hand mirrorless bodies.
| Model | Release | Sensor | Rated Shutter Life | RAW Format |
|---|---|---|---|---|
| Canon EOS R5 | 2020 | 45 MP full-frame | 300,000 | CR3 |
| Canon EOS R5 Mark II | 2024 | 45 MP full-frame | 500,000 | CR3 |
The Canon EOS R5 does not show the shutter count in its on-screen menus. The count is written into the MakerNote of every CR3 RAW file. To read it:
You can drop multiple CR3 files at once to check counts across an entire shooting session or compare two bodies side by side.
When buying a second-hand Canon R5, the actuation count tells you how much of the rated 300,000-shot shutter life has been consumed.
| Actuation Count | % of Rated Life (R5) | Assessment |
|---|---|---|
| 0 – 30,000 | 0 – 10 % | Very low use — near new |
| 30,000 – 90,000 | 10 – 30 % | Low use — plenty of life remaining |
| 90,000 – 180,000 | 30 – 60 % | Moderate use — normal for active shooters |
| 180,000 – 270,000 | 60 – 90 % | High use — negotiate price accordingly |
| 270,000 + | 90 %+ | Near or past rated life — budget for shutter replacement |
For the R5 Mark II (rated 500,000), scale proportionally: under 50,000 is very low use; 150,000–300,000 is moderate; above 400,000 is high.
Both the R5 and R5 Mark II write images in Canon's CR3 format — an ISOBMFF (ISO Base Media File Format) container. ShutterCount parses the box hierarchy to locate the embedded EXIF block, then reads the Canon MakerNote.
The shutter counter is stored as a uint32 little-endian value at a model-specific byte offset within the MakerNote:
0x0AF1 inside the CameraInfo block0x069C (different block layout introduced with the Mark II)These offsets have been validated against actual R5 and R5 Mark II CR3 files from multiple firmware versions. All processing happens in your browser — the file never leaves your device.
Canon does not embed the shutter counter in the MakerNote of JPEG files produced by the R5. Use a CR3 RAW file. If you shoot RAW+JPEG, use the CR3 side of the pair.
No. The R5's electronic shutter uses the sensor's rolling readout without moving the mechanical curtain. Those frames are not counted. Only mechanical shutter and EFCS exposures increment the counter. The R5 Mark II adds a partially-stacked sensor readout; those silent shots are also not counted.
Shoot a CR3 RAW file with your R5, then drop it into shuttercount.app. The shutter count is read from the file's MakerNote entirely in your browser — no upload needed.
Canon rates the EOS R5 at 300,000 actuations and the EOS R5 Mark II at 500,000 actuations. Both are median estimates.
Only a Canon authorised service centre can reset the hardware counter, and only after a physical shutter replacement. EXIF-editing tools overwrite metadata but cannot alter the in-camera counter. Always verify from an original CR3 RAW file.
No. The silent electronic shutter bypasses the mechanical curtain entirely and does not increment the count. Only mechanical and EFCS exposures are counted.
Canon changed the internal CameraInfo block layout between the R5 and R5 Mark II. The original R5 stores the count at offset 0x0AF1, while the Mark II uses 0x069C. ShutterCount automatically detects the model from the CR3 metadata and applies the correct offset.
ShutterCount supports the full Canon EOS R system. See related guides:
