Drop a CR3 RAW file from your Canon EOS 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 Mark II (2024) is Canon's flagship hybrid mirrorless camera, succeeding the hugely popular original R5. It features a new 45 MP partially-stacked CMOS sensor with eye-control AF, improved thermal management for extended video recording, and a mechanical shutter rated at 500,000 actuations — one of the highest ratings in Canon's mirrorless lineup.
| Model | Release | Sensor | Rated Shutter Life | RAW Format |
|---|---|---|---|---|
| Canon EOS R5 Mark II | 2024 | 45 MP full-frame (partially stacked) | 500,000 | CR3 |
| Canon EOS R5 | 2020 | 45 MP full-frame | 300,000 | CR3 |
| Canon EOS R1 | 2024 | 24.2 MP full-frame (stacked) | 500,000 | CR3 |
The Canon EOS R5 Mark II does not display the shutter count in its menus. The count is written into the MakerNote of every CR3 RAW file at offset 0x069C.
With a rated shutter life of 500,000 actuations, the R5 Mark II has one of the most durable shutters in its class.
| Actuation Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 50,000 | 0 – 10 % | Very low use — near new |
| 50,000 – 150,000 | 10 – 30 % | Low use — plenty of life remaining |
| 150,000 – 300,000 | 30 – 60 % | Moderate use — normal for active shooters |
| 300,000 – 450,000 | 60 – 90 % | High use — negotiate price accordingly |
| 450,000 + | 90 %+ | Near or past rated life — budget for shutter replacement |
The R5 Mark II writes images in Canon's CR3 format — an ISOBMFF 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 byte offset 0x069C within the CameraInfo block. This offset was introduced with the R5 Mark II and differs from both the original R5 (0x0AF1) and the newer R1/R6 III generation (0x086D).
No. The R5 Mark II's electronic shutter uses the partially-stacked sensor's rolling readout without engaging the mechanical curtain. Those frames are not counted. Only mechanical shutter and EFCS exposures increment the counter.
Shoot a CR3 RAW file with your R5 Mark II, then drop it into shuttercount.app. The shutter count is read from offset 0x069C in the file's MakerNote entirely in your browser — no upload needed.
Canon rates the R5 Mark II at 500,000 actuations, matching the EOS R1 and significantly exceeding the original R5's 300,000 rating.
Only a Canon authorised service centre can reset the hardware counter 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.
The R5 Mark II features a partially-stacked CMOS sensor (vs conventional BSI on the R5), eye-control AF, improved thermal management, and a higher shutter rating (500k vs 300k). The CR3 shutter count offset changed from 0x0AF1 to 0x069C.
ShutterCount supports the full Canon EOS R system. See related guides:
