Awesome, I think me having zero exp in Photo Mechanic makes me appreciate your (and Jeff's) skills more!
Behind The Shot interviews Jeff Cable, to talk about using the EOS R3 in the real world

This is very educational, and I appreciate the insight from a legitimate and credible professional working photographer. If there's anyone interested in this camera, or Canon in general when it comes to photography, I highly recommend it. I didn't think I'd watch more than 5 minutes but I sat through the whole thing because it actually elevated my sports photography.
It's a shame that all people care about is listening to YouTubers that review cameras and have shit for photography.

EFCS itself doesn't have a DR penalty, but it does unlock higher FPS modes on the R5 which to come with a DR penalty regardless of shuttermode, you'll go from 14-bit to 13-bit captures when doing more than 8fps.
ES means fully electronic shutter, not EFCS.
Believe me, you aren't the only one.
I find the button utterly useless, and would love to be able to use it for something else, but it's not only the most useless button on the entire camera it's the ONE button that cannot be changed to anything else.
I did provide Canon feedback via the support channel for the Rate re-map among other potential firmware improvements. Hopefully you have done the same
Maybe all CR readers could provide a solid/coordinated source of feedback this way.
Please see my above post and maybe give the rate button a shot. It can dramatically change the way you edit and deliver images.
not that I know of. I just know the bokeh at high shutters like 1000 and up look worse.
I am curious on why there is a difference in the dynamic range between electronic shutter and physical shutter. Can someone explain why the electronic shutter in the R5 has lower dynamic range below ISO 800? Just curious and want to understand.
The ADCs the photo sensors use are "ramp-compare" type. Which means that in order to evaluate one 13-bit pixel the ADC needs to pass through 2¹³ = 8192 cycles. For a 14-bit pixel, the number of cycles (and thus the time) per pixel doubles.
For the electronic shutter, the rolling shutter effect is determined by the speed of pixel processing (accessing, analog-to-digital conversion, digital throughput). If analog-to-digital conversion is the bottleneck, it is possible to increase its speed by a factor of two or four by dropping one or two bits of its resolution (by doubling or quadrupling the magnitude of the ramp-up step of the ADC).
For the fully mechanical shutter and the EFCS, the rolling shutter effect is determined by the speed of the mechnical shutter, and then the sensor readout could be continued when the sensor is covered by the mechanical shutter. However, you still need to read the whole sensor before you can start a new exposure. So, to increase your frame rate with EFCS, you may also want to decrease the bitness of your ADC.
For the "natural" (limited by the photon physics) dynamic range of a sensor with Bayer pattern and a pixel pitch of R5 at ISO 800 and above, 12 bits of the value representation are enough, and you don't need an ADC with a higher bitness. Lower ISOs mean potentially more photons per pixel cell and more bits to be useful for recording the full DR.

Thank you for the detailed explanation. If I understand correctly, having a stacked sensor with a faster readout might improve the dynamic range in electronic mode? Can has stated that the R3 shoots 14-bit files @ 30 fps with the electronic shutter so hoping that dynamic range is very good with the ES.
I'm not sure about DR. I don't usually pay attention to that. The only confirmed penalty I've seen is a slight deviation in the bokeh at certain shutter speeds. Something I'd never notice without the videos or research I saw. I personally just shoot my R5 on mechanical. I mainly shoot sports, and I am happy with the 10-12 frames I can get. And I don't shoot slow shutter speeds so the reduced vibration from EFCS also isn't a factor.
I can't possibly usefully "rate" images based on a 2 inch tall image on the back of the camera, especially not in daylight.
I do that process at home.
Button is useless to me. Utterly, completely useless.
If you have a stacked sensor, you can put much more electronics onto it. In particular, you can increase the number of ADCs working in parallel, and then your bottleneck will no longer be the ADC.
OK, so change your magnification button to zoom 1:1 on the AF point to check focus in the field. Benefit of an EVF is now you can keep your eye to the viewfinder on a sunny day when required. It's what most of us are doing and it's PROBABLY why there is a button called RATE on nearly all professional cameras and why it's one of the first things I look for on any new camera body I consider...because we're using it in the field to save time when we get them on the computer. If you're not willing to do any of this then best of luck to you in the future. Just trying to save you time and demonstrate another approach to culling images that was taught to me by one of the greatest photographers I know.
If I can interrupt photographing things long enough to do all that, then instead of rating the bad pictures, I'll simply delete them.
But I'd rather spend that time AFTER the job when it doesn't cut into my time on site.
But realistically, even if some people find it useful and others find it a waste of time...the REAL issue is why Canon won't let you reassign the button.
If I could do that, I wouldn't give a damn about the rate function. Instead I end up resenting it because it uses up what could otherwise, to me, be a valuable button. The fact that YOU and unspecified pros find it useful doesn't change the fact that the button is unassignable for those who do not.

This means Jeff Cable is a Canon Ambassador.
That means Jeff Cable is being paid (in money or cams) to tell the world Canon is great!
That means you are watching a commercial.
The R3 is 24 mpix guys.. Nikon is doing 45mpix, Sony is doing 50mpix. What is Canon doing?? It’s almost 2022. 24 mpix, seriously? Sure, incredible AF. But 24 mpix?
I am waiting so long for a Canon mirrorless pro camera, but I’m gonna skip this one.. keeping my fingers crossed for Canon to make an epic R1 with a reasonable pricetag. If not, I’m off to Sony too…

i gather from this you do not feel like the R3 will improve your results. i can only say the move from 5d4 to r5 has greatly improved my results, and the resolution really isnt the biggest piece of the puzzle. i wonder about the 'sensor splatter' that is what kept me out of the 1d series. i perhaps electronic shutter has reduced the moving parts to the point that there is no issue.
That was an issue with the 1D X only, although mine never had an issue. Canon issued a service notice (in 2013, I think) and fixed the problem for free.
