ShutterCount does not return a verified shutter count for the Canon EOS M50 Mark II. Since 28 October 2026 it shows a “Possible shutter count (unverified)” read from a CameraInfo position found by a research scan — 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 0x0ACF, with the note that the position was found by comparing files of this body and is not confirmed by Canon or ExifTool.
The tool identifies the body by the model string Canon writes into the file, Canon EOS M50m2, so the card may show that name rather than “M50 Mark II”.
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.
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 M50 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 M50 Mark II it found it at the same position, 0x0ACF, in files from two different bodies (values 1,601 and 7,578) and at the same position in a file from the EOS R100 (672), a sibling that shares the sensor generation. The same scan recovers the three known offsets on every file of the bodies that have them, which is why its findings are worth showing at all.
One file per body shows a plausible number, not a counter. 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 M50 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 M50 Mark II has no menu item that shows the shutter count.
The Canon EOS M50 Mark II (2020) was Canon’s most popular entry-level EF-M mirrorless camera, aimed at vloggers and enthusiasts stepping up from a phone: a 24.1 MP APS-C sensor, Dual Pixel autofocus and a fully articulating touchscreen. It is extremely common on the used market, which is exactly why a trustworthy count would matter.
| Model | Release | Sensor | Shutter life | RAW Format |
|---|---|---|---|---|
| Canon EOS M50 Mark II | 2020 | 24.1 MP APS-C | ~100,000 (est.) | CR3 |
| Canon EOS M50 (original) | 2018 | 24.1 MP APS-C | ~100,000 (est.) | CR3 |
Canon publishes no shutter durability rating for either body; its specification pages list the shutter type and speed range only. The ~100,000 figure is a class-norm estimate for entry-level bodies, not a Canon number, and an individual shutter can fail earlier or last much longer.
As rough reference points against that estimate: under 10,000 is light use; 10,000–40,000 is typical hobbyist use with plenty of life left; above 80,000 price accordingly and budget for a possible shutter service. Combine any count with a sensor inspection and a check of the autofocus and shutter sound.
Not as a verified value. Since 28 October 2026 the tool shows a “Possible shutter count (unverified)” for the M50 Mark II, read at CameraInfo offset 0x0ACF — 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.
A record shaped exactly like the verified EOS R5 / R6 counter (a marker word, six zero bytes, then a 32-bit number) sits at the same position, 0x0ACF, in files from two different M50 Mark II bodies (values 1,601 and 7,578) and from an EOS R100 (672). That is consistent with a counter, but no file from a body with a known count has confirmed it yet.
Set the camera to RAW or RAW+JPEG, 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”.
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 M50 Mark II; its specification pages list the shutter type and speed range only. Figures you see elsewhere, usually around 100,000 actuations, are estimates based on comparable entry-level bodies, not a Canon figure.
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 M50 Mark II, so check the tool’s own compatibility list first. When buying used, ask the seller for one of these before you pay.
No. The candidate position lies in the CameraInfo block of the CR3 file’s CTMD metadata track, which a JPEG does not carry. Use original, unedited CR3 files straight from the card; a file re-saved by editing software may have the block stripped.
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 M50 Mark II. Shutter type and speed range: Canon’s EOS M50 Mark II specification pages, which state no durability rating.
ShutterCount reads some Canon bodies and not others — each guide says which.
