Canon has released new firmware for the Canon RF 100-500mm f/4.5-7.1L IS USM to improve performance with the Canon EOS R3.
Firmware Version 1.1.0 incorporates the following improvement:
- Improves performance of the image stabilization when using the electronic shutter of the EOS R3 camera during still image shooting.

I suspect we will not see anything other than 3 / 15/ 30 fps for the e-shutter fps options on the R3. That sort of thing is generally not something Canon will change in a firmware update. I'd expect the R1 to be more customizable regarding fps selection, those sorts of adjustments are the province of 1-series bodies.
Anyway, I suspect that I'll (should I not cancel my pre-order) use 15fps most of the time for action photography. I shot a 2-day cross country meet this weekend using my R5's 20fps e-shutter and ended up with over 6,000 images to process. That was not fun! Notably, the 100-500 performed like a champ. Despite my initial skepticism about f/7.1 at 500mm, this lens produces magic at every focal length.
Do keep in mind that there is a cost associated with implementing any function, even in software. On the surface, it seems like it should be a simple matter to take a feature in one camera and implement it in another, and that doing so should be 'free'. But that's not the case.
As a counterexample, when the 1D X came out there was a bug in the AF Microajustment such that the lens-specific values were not stored...but only if the option orientation-linked AF point was selected. Both features were available on previous cameras, but when implemented on the 1D X one setting borked the other. It took me and another forum member to get to the bottom of it. I found the AFMA bug, but not the association with the orientation-linked AF point, the latter enabled Canon to reproduce the issue and led to them developing a firmware update to fix it. So two 'free' features from previous cameras...weren't so free.
That’s precisely why Canon and other brands state the *maximum possible burst rate under ideal conditions*, and ambiguous settings such as “high”, “medium” and “slow” burst rates.
My point is that although that level of customization isn’t available outside the 1-series, I bet it will be possible on the R1.
@Billybob no need to give Canon the benefit of the doubt – a user-defined max frame rate is quite possible, but Canon reserves that feature for 1-series bodies. It’s simply product differentiation. I’d really like AF point-linked spot metering on my R3, but I’m not getting it…because it’s not the R1.
My R5, and all of the Canon DSLRs I’ve owned in the past, have tended to over-expose (for my usage) at default metering settings, causing me to set minus 1/3 or minus 1/2 stop as my baseline setting.
AFAIK, on most modern Nikon cameras it is possible to set up to a stop of what you refer to as “background EC” in 1/6 stop increments, at least that was the case with my D610.
Could it be the case that in electronic shutter mode there is some form of digital stabilisation, in addition to IBIS and OIS. Seems unlikely, unless it is only active in video mode.
