Drop a CR3 file from your Canon EOS R6 Mark II and get the exact mechanical shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Canon EOS R6 Mark II is Canon's 2022 all-around full-frame mirrorless camera. It replaces the original R6 with a substantially upgraded 40MP sensor (up from 20MP), a 40fps electronic burst with subject tracking, improved dual-pixel autofocus, and a host of video improvements including 6K RAW video output. The mechanical shutter is rated at 300,000 actuations, positioning it squarely between the entry-level R8 and the flagship R5 and R1.
| Model | Release | Resolution | Rated Shutter Life | Position |
|---|---|---|---|---|
| Canon EOS R6 Mark II | 2022 | 40 MP full-frame | 300,000 | All-around |
| Canon EOS R5 | 2020 | 45 MP full-frame | 500,000 | High-resolution |
| Canon EOS R8 | 2023 | 24.2 MP full-frame | 200,000 | Entry full-frame |
| Canon EOS R1 | 2024 | 24.2 MP full-frame stacked | 500,000 | Pro flagship |
Note: use a file shot with the mechanical shutter, not electronic shutter. Electronic shutter frames do not increment the counter and may return a misleading (lower) value.
| Shutter Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 10,000 | < 4 % | Lightly used |
| 10,000 – 60,000 | 3 – 20 % | Normal use for age |
| 60,000 – 150,000 | 20 – 50 % | Moderate use — inspect carefully |
| 150,000 – 270,000 | 50 – 90 % | Heavy use — price accordingly |
| 270,000 + | 90 %+ | Near or past rated life |
Shutter ratings are statistical averages. Many R6 Mark II shutters will last well beyond 300,000 actuations, but the risk of failure rises after the rated figure. Factor shutter replacement cost (€200–350) into negotiations when the count is high.
Canon CR3 files use the ISOBMFF container format. The shutter count is stored in the MakerNote CameraInfo block embedded in the CR3 metadata. ShutterCount parses this block and extracts the image count value. All processing is done locally in your browser — no file data is ever transmitted to a server.
This method applies to all Canon EOS R-series bodies that shoot CR3 files, including the R1, R5, R6 Mark II, R7, R8, R10, and R50. The EOS R1 is the exception: it uses a unique uint16 ImageCount field at offset 0x086D.
Shoot a mechanical shutter CR3 frame and drop it into shuttercount.app. The count is read from the CR3 MakerNote CameraInfo block in your browser, instantly and privately.
Canon rates the R6 Mark II at 300,000 actuations — the mid-tier of the Canon RF lineup, above the R8 (200,000) and below the R5 and R1 (both 500,000).
Both support Canon's excellent Dual Pixel CMOS AF II with animal and vehicle tracking. The R5 wins on resolution (45MP vs 40MP), EVF quality, and shutter rating (500,000 vs 300,000). The R6 Mark II is lighter and more affordable; for most sports use, the autofocus system is essentially identical. Consider the R1 if you need the absolute fastest frame rate with stacked sensor readout.
Only Canon authorised service centres can reset the counter. Always verify the count from an original CR3 file, not a screenshot.
No. The 40fps electronic burst mode uses an electronic (silent) shutter and does not increment the mechanical shutter counter. Only frames shot with the mechanical shutter count toward the 300,000-actuation rating.
