Canon C300 Mark III still supported?

Hey folks,

I was hoping someone could let me know if the Canon C300 Mark III is no longer supported. I saw that the C70 will be getting an update in the future with the C80, C400 and R5C and was curious if the C300 Mark III will be getting anything or support has ended.

Greetings,

The C300 Mark III is still under current support. The last firmware update was about 9 months ago. Not sure when/if another update will be provided.

Yeah, it always gets me but thankfully Canon are slowly changing. Canon's, so called, 'Pro' cameras, C300/C300 MK II/C300 MK III, C500 MK I/C500 MK II and C700/C700 FF pretty much only get one bug fix firmware update, when 'Prosumer' cameras, C70/C80 and C/R range of DSLR/Mirrorless get multiple new features and bug fixes etc.
