The Canon RF 70-200mm f/4L IS USM has appeared for Russian certification (SKU 4318C005A), which means we should get an official announcement soon. I expect to see the RF 50mm f/1.8 IS STM to be announced alongside it.
While we don’t have an exact announcement date, we may see them announced in a few weeks alongside the new RF mount Cinema cameras and other new gear.

I don’t think it comes as a surprise that Canon will be releasing firmware updates for the Canon EOS R5. I have been told that we will see an update “soon”, no date was given. As with most firmware updates, it’ll be released when it’s done.
The source claims the following will be added to the Canon EOS R5, but cautions it may not come all at once in a single firmware update.
Addition of Cinema RAW light option to 8K recording
Addition of CLog 3
Increased record time limits (but don’t expect a huge boost)
Various bug fixes
These additions may not be all that is coming, but the source claims these features are what’s coming first.
Here we have our first teardown of the Canon EOS R5, and it will give you some idea in how Canon has chosen to control heat. There are a few design choices that I find interesting.
The thermal pads on the CPU don’t cover the full CPU
Aluminum was used instead of copper, though there is added cost and complexity of working with copper.
There is definitely no venting for heat to escape
Is there an issue with the CFExpress slot being so close to the processor?
As pointed out by EOSHD, why does not of this matter when recording externally? I and others think it’s probably some kind of software limit.
