Both bodies carry the same 200,000-actuation rating, so shutter durability is a wash — your buying decision comes down to sensor, features and price, not shutter wear.
Rated figures are manufacturer estimates, not hard limits. Many bodies shoot well past their rating, while a small number fail earlier — the rating is best read as a durability class, not a countdown. When buying used, what matters is the actual actuation count relative to that rating, which you can read for free below.
Both bodies launched in 2023, so neither has a clear generational advantage; the choice is about sensor and handling rather than age.
On resolution the A7C II leads at 33 MP full-frame against the R8’s 24.2 MP full-frame — worth having if you crop hard or print large, while the R8 keeps file sizes and low-light noise in check.
Remember you are also choosing a system: Canon (CR3 files) and Sony (ARW files) have different lens line-ups, so weigh the glass you already own or plan to buy.
The R8 writes CR3 files and the A7C II writes ARW files — ShutterCount handles both formats natively.
See the full model guides for each body: Canon EOS R8 shutter count and Sony A7C II shutter count.
Both the Canon EOS R8 and the Sony A7C II are rated for 200,000 shutter actuations, so neither has a durability edge on paper.
Take a photo, then drop the resulting CR3 (R8) or ARW (A7C II) RAW file into shuttercount.app. The count is read from the file’s MakerNote entirely in your browser — no upload, no account.
Both launched in 2023, so compare them on sensor, handling and price rather than age. Always verify the actual shutter count from an original RAW file before buying.
No. Only the manufacturer’s service centre can reset the hardware counter, and only after a physical shutter replacement. EXIF editors can rewrite surrounding metadata but cannot alter the in-camera counter, which is why you should always read it from an untouched CR3/ARW RAW file.
