ShutterCount does not return a verified shutter count for the Canon EOS M6 Mark II. Since 28 October 2026 it shows a “Possible shutter count (unverified)” read from a CameraInfo position found by a research scan — seen in one file of this body so far, and not confirmed by Canon or ExifTool. Drop two consecutive shots and the tool checks whether that number rises; your report helps turn the candidate into a supported body. Files are parsed in your browser and never uploaded.
Open the Checker →Drop an unedited CR3 from the camera and the result card shows the model, firmware, capture date, settings and lens, read locally. Below them, a separate field labelled “Possible shutter count (unverified)” shows the number read at CameraInfo offset 0x0AC7, with the note that the position was found by comparing files and is not confirmed by Canon or ExifTool.
A single file cannot tell a counter from any other number. Two files taken one after the other can: a shutter counter must rise by exactly the number of exposures between them. For the M6 Mark II, with only one file in our corpus, this check is the first evidence that the field moves at all.
The report carries the model, firmware, offset, the two values, the two capture dates and your shot count — no file, no serial number, no e-mail address. Mismatches are as useful as matches: they tell us where the candidate fails.
Canon keeps the counter of its CR3 bodies in a model-specific CameraInfo block (CTMD tag 0x000D). Every counter ShutterCount reads with confidence — EOS R5 / R6 at 0x0AF1, R6 Mark II / R8 / R50 at 0x0D29, EOS R at 0x0194 — sits in the same kind of record: a 16-bit word pair fourteen bytes earlier, six zero bytes, then the 32-bit count. ExifTool documents no CameraInfo table for the M6 Mark II and decodes no shutter count for it.
A systematic scan of every Canon CR3 in our release corpus and the visitor samples looked for that record shape wherever it occurs. On the M6 Mark II it found it at 0x0AC7 in the single file we have (value 5,760), and at the same position in the single EOS M200 file (116) — a sibling with the same processor generation. Two files, one per body: the offsets agree, but nothing has yet been shown to rise on one body, which the EOS RP and M50 candidates, for example, have. That is weaker evidence than for most bodies on the candidate list, and the page says so.
Even a two-shot match proves only that the field rises per exposure; it cannot rule out a counter that resets when the card is formatted. Canon does write such fields — ExifTool documents an ImageCount on the EOS R6 Mark III that “resets to 0 when SD card is formatted” — and a card-relative number would pass the two-shot check just as well. That is why the tool reads the value only when the six zero bytes are present, caps it below 1,000,000, and still labels it as possible.
One CR3 from a body whose count is known from Canon service or a USB tool, or several two-shot matches plus a file from a body that has formatted its card many times. The M6 Mark II moves to “supported” only when both lines of evidence agree. If you have such a file, please write to samples@shuttercount.app; this is an invitation to help, not a promise that support will follow.
The image file number (for example IMG_1234.CR3) is not a shutter count: it rolls over at 9999, can be reset in the menu and continues across cards. The M6 Mark II has no menu item that shows the shutter count.
The Canon EOS M6 Mark II (2019) was the high point of the now-discontinued EF-M system: a 32.5 MP APS-C sensor, 14 fps with the mechanical shutter and 30 fps with the electronic shutter, in a compact rangefinder-style body. Because it can shoot silently without cycling the mechanical shutter, a used M6 Mark II can have taken far more frames than its mechanical count shows — whatever that count turns out to be.
| Model | Release | Sensor | Shutter life (Canon) | RAW Format |
|---|---|---|---|---|
| Canon EOS M6 Mark II | 2019 | 32.5 MP APS-C | Not published | CR3 |
| Canon EOS M200 | 2019 | 24.1 MP APS-C | Not published | CR3 |
| Canon EOS M50 Mark II | 2020 | 24.1 MP APS-C | Not published | CR3 |
Canon publishes no shutter durability rating for any EF-M body; its specification pages list the shutter type and speed range only. Figures quoted elsewhere are estimates from comparable bodies, and an individual shutter can fail earlier or last much longer.
Silent-mode-heavy users — street, wildlife and stage photographers — often show mechanical counts far below the body’s real use, so judge the count together with the body’s age and condition: inspect the sensor, test the autofocus and listen to the shutter. As rough reference points, under 10,000 mechanical actuations is light use and above 70,000 deserves a lower price and a budget for possible service.
Not as a verified value. Since 28 October 2026 the tool shows a “Possible shutter count (unverified)” for the M6 Mark II, read at CameraInfo offset 0x0AC7 — a position found by a research scan of CR3 files, not confirmed by Canon or by ExifTool, which decodes no count for this body. It is never used for the verified certificate, the PDF report or the value estimate.
Weaker than for most other candidate bodies. A record shaped like the verified EOS R5 / R6 counter sits at 0x0AC7 in the one M6 Mark II file we have (value 5,760) and at the same position in the one EOS M200 file (116). Two files, one per body, and nothing yet shown to rise — which is exactly why the two-shot check matters for this camera.
Set RAW or RAW+JPEG, switch silent (electronic) shutter off, take two photos one after the other, then drop both CR3 files into shuttercount.app. When two files from the same body are on the page, the result card shows by how much the possible count rose between them. If it rose by exactly the number of photos you took, the field behaves like a shutter counter; you can then press “Report this result”.
We do not know yet. Silent electronic-shutter frames do not cycle the mechanical curtains, and whether this field counts them is untested. Run the two-shot check with the mechanical shutter first; a second pair of silent-mode shots, reported separately, would tell us how the field treats electronic frames.
The camera model, firmware, the offset, the two possible-count values, the two capture dates and how many shots you say you took between the files. No image file, no serial number and no e-mail address is sent. The files themselves are parsed locally in your browser and never uploaded.
Canon has not published a shutter durability rating for the EOS M6 Mark II; its specification pages list the shutter type and speed range only. Any figure you see elsewhere is an estimate from comparable bodies, not a Canon number.
Ask a Canon authorised service centre, which can read the release count when it inspects the camera (availability and fees vary by country). Some third-party tools read a count over a USB (PTP) connection; we have not confirmed that any of them supports the M6 Mark II, so check the tool’s own compatibility list first. When buying used, ask the seller for one of these before you pay.
The candidate position, its record shape and the values quoted above: ShutterCount’s systematic scan of the release corpus and visitor samples, documented in the project README under “Research: Canon CameraInfo counter candidates” (28 October 2026). The verified R5 / R6 counter record the shape is compared against: the CameraInfoR6 table in the ExifTool Canon tag reference, which also documents the card-format-resetting ImageCount on the R6 Mark III and lists no CameraInfo table for the M6 Mark II. Shutter type, speed range and burst rates: the Canon Europe EOS M6 Mark II specifications, which state no durability rating.
ShutterCount reads some Canon bodies and not others — each guide says which.
