Went through all posts and only one other person mentioned DLA. is it a limiting factor?

For a landscape photographer, what is the advantage if diffraction causes loss of sharpness at apertures smaller than f/5, which landscape togs typically shoot at?
More resolution is always better, even if you hit somewhat diminishing returns due to diffraction. Diminishing returns does not mean no returns.

Nice! Hope I am finally in a situation I can viably switch to my first mirrorless R1 or R5s.
Quite happy using my 5dsRs on tripod still for arhictecture and still life. Would be nice to ditch the tripod in some situations to speed up workflow & shoot movin subjects for a change. Would be nice to ditch the tripod & bump the iso to a usable 400-800+ with IS & maintain a decent amount of HRD to push shadows and pull down highlights in post!

The idea is that in crop mode smaller files recorded, meaning an effectively bigger buffer and maintenance of a faster frame rate for a longer time. The camera has to support that, though.
This all comes down to whether a R5 equivalent sized body can handle the heat dissipation.
Canon's Digic X is powerful but not as efficient as Sony's processors. This is looking purely at battery life, CIPA numbers and a smaller body. The A1 doesn't handle the same bandwidth needed for 8kraw and hence CFe Type B cards but it is a smaller body than the R5. Although the A1 records compressed 8K it is oversampling and compressing via the processor rather than using the bus for higher data flow.

I suggest that Canon needs a new/more efficient processor for the R1/R5s. Previous 1DX models have had multiple processors but I don't think that the R1 will be a larger size than the R3 precedent.

I don’t understand the need to crop in camera? Wouldn’t cropping in post have the same result plus the ability to choose a variety of post capture compositions? I’d rather do it in post. I have the R5 and forgot it has the ability to crop in camera because I’ve never thought to use it. I’m primarily a portrait photographer though.
I don't use crop mode in my R5. I crop in post if needed.
Faster frame rate may be possible (and theoretically lower rolling shutter and flash sync) only if the sensor is clever enough to only read the crop portion of the sensor. Do we have any evidence that Canon sensors have done this in the past?

Another reason to use crop mode is that for some competitions, cropping (or at least severe cropping) would not be allowed. When underwater, you can't change lenses but activating crop mode could be one advantage in this case.

Only if the heat management can be better than the R5
To be fair, in the latest firmware the heat problems are prety well managed.
4k25 - no problem
4k25 hq oversampled from 8k - 20-30 minutes runtime
4k50 - rarely any problems
4k100 is the most problematic mode, where overheat may happen after 5 minutes. Though I rarely ever need that much of record time. :)

100+ megapixels on FF would be a 1st and A LOT for the sensor size. Be interesting to see what ISO performance is like and which of the RF lenses can resolve those megapixels and resolve them well.
Just hope for potential buyers there’s no AA filter.
No AA filter would be fine for landscape but wouldn't be okay for portrait and video usage. I know that some people don't use cameras for stills and video but you can't get away with this now.

12K DCI resolution is 12288 x 6480 for a total of 79,626,240 pixels (~80 MP) which would mean ~102mp stills at 3:2
This fits with the rumour and would be a first for Canon to both have the first 8k MILC and the first 12K MILC

This. When photographing smallish subjects at a distance, the focus accuracy is significantly improved by using the crop mode.
I am not following this... Less pixels overall in crop mode means that the processor is not looking at the entire sensor for focus targets but the tracking is only pixel to pixel which wouldn't change from crop or full sensor. Has there been any tests for this?

From what I understand of landscape medium format photographers, they need to focus stack to ensure sharpness front to back because of this issue (DLA and depth of field)

Agreed but I do find 4k30 HQ and 4K120 to run into problems quickly. Note that generally use these modes underwater and there is a partial vacuum inside the housing meaning less heat conduction. A specialist niche of course.
The A1 (maybe because of processor efficiencies, lower bandwidth and higher temperature limits) in a smaller body doesn't suffer. The A1 will be the reference body that it is measured against. Canon won't go through the R5 overheating issue again

I think the context is not that it’s the camera’s focus accuracy that is improved by crop mode, but rather the photographer’s ability to accurately select and track a small subject.

The point of a crop camera is $1500 vs $3800. And cropping the $3800 camera gives you only 17MP vs 32MP.

Yes, I would imagine that is the case. It certainly "seems" that the magnified view in crop mode makes it easier to, say, select the eye rather than simply the head. Whether it is the camera or the photographer I don't know.
