Canon EOS R6

Shutter units on high-count bodies fail predictably; keep the actuation log before you open it.

Repairability

4/ 10

medium risk

41% of cases

Symptom: Err 20/30 on release, black frames, or an audible double click.
Diagnosis: Shutter blades stick after high actuation counts; the magnet coil weakens before it fails outright.
Solution: Replace the shutter unit and reset the actuation counter.
