I wonder then the R1 will land and how much it will cost given the information we have learned with the R3. I would really hope to get something regarding the difference in low light and DR vs the R5 and R6.

That precedent could change due to the change in mount this time around. Canon is really pushing the RF mount and the 1DX3 helps sell exactly 0 RF lenses. Therefore there is an incentive for them to shorten the upgrade cycle this time.
Exactly, and if we go back to that last precedent, FD-EOS, the New F-1 to EOS-1 was eight years, though nobody expects that kind of delay.

And to be sure there is no one right way, sometimes blown out exteriors for the mood or because of the view are the right way anyway, whereas sometimes showing the exterior view to full effect is the entire point of the building.

Nice natural balance (y)
Just to be pedantic; the brain sees, not the eye which is why we are able to see things in the way you describe, and why some people really do see ghosts - even though they are not really there !

I think that there are 2 points here: capture time for the sensor and read out time for the sensor. The read out time will define how fast the continuous fps will be. The capture time will dictate the fastest shutter speed. Mechanical shutters get to 1/8000s but they get there by a slit travelling over the sensor. It may be much less with a global shutter. Interesting to see how it is implemented :)

By "less" I think you mean longer. 1/1000 or 1/4000 is more than 1/8000, not less.

But what about the rear position of the vertical hold control wheel instead of on the righthand end of the camera, just behind the vertical shutter button?
You're confusing two different dials. The R3 also has the "main dial" directly behind the shutter button on the top of the grip in addition to the the new third wheel on the top of the back of the grip.

I disagree there.
R5 and R6 are selling like hotcakes but so are M50 and the Rebel cameras.
The rumored ZV-E10 and Z30 seem like threats to the dominance of Canon, especially with so many people declaring their M system and DSLRs dead.
While these threats might not materialize, Canon should not be 100% reactive.
How many times has Canon been D*O*O*M*E*D because they didn't offer a camera with identical specs and price to that of a competitor. According to the internet, they were dead and buried long ago. Yet here we are.

A lot of speculation about the resolution of this camera .
It appears to be very much a specialised body for sports photographers so I think it will only be 20-24 mp for 3 reasons :
- smaller files speed up the camera as the processor can work faster
- smaller files mean a faster work flow
- most professional sports photographers have suitable Big White lenses and they don't need to crop much and usually are working in arenas which are well lit and human subjects are quite large and don't move very fast (less than 30mph). Motorsports move very fast but in a very predictable way that's easy to track and the Pros are in ideal positions to shoot from.

I really like this camera but for hobbiests like my self who shoot birds in flight especially small fast moving and unpredictable species like swallows, kingfishers and flycatchers a crop sensor version of this camera with 30-35mp would be an ideal camera.

I wonder how many full time professional sports shooters there are compared to amateur bird shooters ?
I suspect we out number them at least 10 to 1 , here in New Zealand I would think there are only a few dozen sports pros in the country but hundreds of amateur bird shooters (similar ratio in the rest of the world I suspect) so I think the market for a really good crop sensor camera is pretty large.

Personally I'd be prepared to pay a similar price to an R6 (in my dreams a bit lower still) for such a camera but whether Canon chooses to make one at such a price who knows ?

I don't think camera companies make much profit on these flagship bodies (which have very small production runs) but probably make good margins on lenses and making the best ones must help sales of more affordable cameras.

Here in the U.S., I'd think that amateur sports photographers outnumber amateur birders by at least 10:1, probably more like 20:1. There are handfuls of them on the sidelines at every high school football game, which is by far the biggest amateur sport in the U.S. (college sports are not "amateur", no matter what the NCAA claims). Baseball/softball and soccer have their share, too.

If both are 30 FPS then it is still fine.
Even better would be if WIFI is also 30 FPS.
30fps until the buffer is full. Then you're at ever how many frames clear the buffer per second. If the buffer is sending data to both the CFexpress bus and the SD card bus at the SD card speed, it will take significantly longer to clear the buffer of the same amount of data than when the CFexpress bus is operating at its higher speed.

39 MP is all that is required for UHD 8K.
Since Canon is only claiming downsampled 4K and RAW I assume it will be significantly less than that.
I do not see the point in going 35 MP instead of 39.
So somewhere between 20 and 30 makes sense and I am guessing it will be closer to 30.

UHD 8K is 16:9. Extend that width to a 3:2 sensor and you have 44-45 MP.

If the sony A1 costs $6500 and does 30fps and 50mp, it would be crazy to buy the R3 at $6000 if it has less than 36mp. If canon is going to charge almost as much as the A1 it needs to directly compete with it. Anything less is subpar. The LCD screen difference is an insignificant difference, the IBIS in the R5 is plenty.

If your highest priority is MP, then the R3 probably is not for you, just like the 1D X Mark III is not for you. Wait for the R1 or go with the Sony α1.

See how easy that is? Not every camera Canon releases needs to meet your specific needs.

I get the joke, but actually Canon has a patent for a new kind of sensor I'm half-expecting to show up on one of the bodies above the R5, that in effect can give you one-shot HDR. It can basically take two exposures, and switch between them at microsecond speeds, so it can give one exposure 1/1000 the light of the other, and have relatively smooth motion blur and so on while also having a super-under-exposed version of the same scene also with smooth motion blur to recover highlights from.

Basically, any architecture/real estate photographer needs this feature to expose a room and also capture the view out the window, so it's not actually that esoteric.

1/1000 as much light is only 3.333 stops, though. Eight stops is 25,600X as much light.

24 MP is 20% more pixels in two dimension than 20 MP. The square root of 20 is 4.47...

But, yeah, the square root of 1.20 is 1.09544...

So you are correct.

But I stand by my opinion that 9.5% more linear resolution has very little practical difference.

The difference between, say, 20 MP and 30 MP is 22.5% linearly. That's significant.

??? A single stop of light is 1/2 as much light (or 2x in the other direction).
So 1/1000 as much light is 10 stops (2^10).
25,600X as much light is LogBase2(25,600) = 14.6 stops.

Yeah, so I used 1/100 as my base instead of 1. Sorry.

I wonder why Canon can't just give us two or three sensor options? Maybe 20, 30 and 60 megapixels. Then everybody would be pleased. Would threy really have to change a lot of the internals ofd a camera, if the megapixel count changes? If the camera can process 60 megapixel images, it should also be able to handle 20 megapixel images. At the moment I am working on hundredsof old photos I took with an 8.2 megapixel APS-H camera and I love how crisp they look on a pixel level. With a high megapixel count diffraction sets in much sooner. Of course you can always downsample those photos, but then you would still have to handle those large RAW files.

The biggest reason those 8.2 MP images look so good at the pixel level is that when you view them at 100% on your monitor you're enlarging them a LOT less than when you view 30 MP or 45MP images on the same monitor.

If you're using a monitor with, say, a pixel pitch of 96 ppi then 100% magnification of 8.2 MP (3504x2336) is the equivalent of a piece of a 36x24 inch enlargement. If you view a 45 MP (8192x5464) image at 100% magnification on the same monitor, it's the equivalent of 85x57 display size!
