Check Shutter Count →The Canon EOS R100 is Canon's 2023 ultra-budget APS-C mirrorless camera. Stripped down to essentials — no viewfinder articulation, no IBIS, no top dial — the R100 targets beginners upgrading from smartphones. With a 24.1 MP APS-C CMOS sensor and a 100,000-actuation mechanical-only shutter, it is Canon's most affordable RF-mount body.

| 60,000 – 90,000 | 60 – 90 % | High use — negotiate price; shutter service approaching |
| 90,000 + | 90 %+ | Near or past rated life — budget for shutter replacement |
The Canon EOS R100 uses the CR3 container format (ISOBMFF-based). ShutterCount reads the shutter count from the MakerNote CameraInfo block embedded in the CR3 file. The R100 shares the same MakerNote structure as other recent Canon APS-C bodies — ShutterCount automatically identifies the correct offset from the camera model recorded in the file metadata.
All processing happens locally in your browser. The CR3 file is never transmitted anywhere.
Shoot a CR3 RAW file, then drop it into shuttercount.app. The count is read from the MakerNote in your browser — no upload needed.
Canon rates the EOS R100 at 100,000 actuations — sufficient for casual and hobby use over many years.
Yes. The R100 offers excellent image quality at the lowest price point in Canon's RF-mount lineup. Its 100,000-actuation shutter is more than enough for typical beginner shooting volumes. A hobbyist shooting 3,000 frames per year would reach the rated threshold in over 30 years.
Only a Canon authorised service centre can reset the hardware counter after a physical shutter replacement. Always verify from an original CR3 file, not a screenshot.
