How the Canon EOS 90D and Canon EOS 6D Mark II compare on rated shutter life, sensor and value — and how to read the exact actuation count of either from a RAW file, free and in your browser.

| Full name | Canon EOS 90D | Canon EOS 6D Mark II |
| Released | 2019 | 2017 |

| Rated shutter life | 120,000 | 100,000 |
The 90D is rated for 120,000 actuations versus 100,000 for the 6D Mark II — roughly 20% more rated shutter life. In practice that means a used 90D at a given actuation count has consumed a smaller share of its rated life than a 6D Mark II at the same count.
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.
The 90D is the newer design (2019 vs 2017), which usually means longer firmware support, a more current autofocus system and a stronger residual value — but also a higher used price.
On resolution the 90D leads at 32.5 MP APS-C against the 6D Mark II’s 26.2 MP full-frame — worth having if you crop hard or print large, while the 6D Mark II keeps file sizes and low-light noise in check.
If you are buying used and plan to shoot heavily, the higher 120,000-actuation rating on the 90D gives you more headroom before a shutter service becomes a consideration.
Because both are Canon bodies, your existing lenses and accessories carry straight across — the decision is purely about the body itself.
The 90D writes CR3 files and the 6D Mark II writes CR2 files — ShutterCount handles both formats natively.
See the full model guides for each body: Canon EOS 90D shutter count and Canon EOS 6D Mark II shutter count.
The Canon EOS 90D is rated for 120,000 actuations, higher than the Canon EOS 6D Mark II’s 100,000. Individual shutters can last well beyond — or occasionally fall short of — the official rating.
Take a photo, then drop the resulting CR3 (90D) or CR2 (6D Mark II) RAW file into shuttercount.app. The count is read from the file’s MakerNote entirely in your browser — no upload, no account.
The 90D is newer (2019), which tends to mean better resale value and longer support; the 6D Mark II is often the better bargain used. 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/CR2 RAW file.
