Canon published a firmware update for the Canon EOS R3 this morning that addresses “the oddity whereby the camera infrequently becomes inoperable” when shooting in Servo AF and utilizing back-button focus, among other things. This issue may or may not be the sporadic crashes that many R3 owners have discussed on numerous forums.
The problem occurs infrequently enough that it hasn’t turned into wild anti-Canon fanboy fodder. An optimist would believe it has implications for resolving some Canon EOS R5 freezes that occur from time to time.
[UPDATE: Canon service employees have assured multiple Canon Rumors forum readers that the R5 freezing issue is actually recognized and will apparently be resolved in a future firmware release.]
The software also offers the option to connect Android smartphones to the body’s new smart display. Allowing the selection of card recording modes when utilizing remote control, adding options for subject tracking control, and “increasing stability” during FTP upload are three other minor faults addressed.
