Drop a CR3 file from your Canon EOS R (the original 2018 model) and get the exact mechanical shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Canon EOS R (2018) was Canon's first full-frame mirrorless camera and the launch product of the RF mount system. It uses a 30.3 MP full-frame CMOS sensor — the same as the EOS 5D Mark IV — with Dual Pixel CMOS AF and 8fps burst. As the first-generation RF body, its mechanical shutter is rated at 150,000 actuations, the lowest rating in the Canon RF lineup. Subsequent generations quickly raised the bar: the R5 and R6 introduced 500,000 and 200,000-actuation shutters respectively.
| Model | Release | Resolution | Rated Shutter Life | Position |
|---|---|---|---|---|
| Canon EOS R | 2018 | 30.3 MP full-frame | 150,000 | Original RF body |
| Canon EOS RP | 2019 | 26.2 MP full-frame | 150,000 | Budget RF body |
| Canon EOS R8 | 2023 | 24.2 MP full-frame | 200,000 | Entry full-frame |
| Canon EOS R6 Mark II | 2022 | 40 MP full-frame | 300,000 | All-around |
| Shutter Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 10,000 | < 7 % | Lightly used |
| 10,000 – 50,000 | 7 – 33 % | Normal use for age |
| 50,000 – 90,000 | 33 – 60 % | Moderate to heavy — inspect carefully |
| 90,000 – 135,000 | 60 – 90 % | Heavy use — price accordingly and budget for service |
| 135,000 + | 90 %+ | Near or past rated life — significant risk |
The Canon EOS R produces CR3 files using the ISOBMFF container format. The shutter count is stored in the MakerNote CameraInfo block embedded in the CR3 metadata — the same location used by all Canon RF cameras. ShutterCount parses this block locally in your browser; no file data is ever transmitted.
Shoot a 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 EOS R at 150,000 actuations — the same as the EOS RP, and lower than every later Canon RF body. The R5 (500,000) and R6 Mark II (300,000) represent significant durability improvements.
The EOS R's 30.3 MP sensor still delivers excellent image quality, and Dual Pixel CMOS AF remains reliable for stills. The 8fps burst and lack of in-body stabilisation are dated by current standards. If you find one in good condition at a very low price, the RF lens ecosystem access makes it a reasonable entry point. For any serious use, the R8 or R6 Mark II offer much better value with higher shutter ratings.
