Is Canon officially announcing two cameras in May?

[P-visie]

Would someone please explain the benefits of a stacked sensor other than read out speeds? Does it give better, similar or worse performance for low light performance or dynamic range? I appreciate those with more technical backgrounds. Thank you!

See DPReview here and here.

You are right to be skeptical.
Believing youtubers is like believing politicians.
99,99% is a speculation, a lie, soni paid propaganda or a pure invention.

Or statistics.

Always good to get the opinion from a real, experienced professional. Thank you Sir for showing me the holy light of Truth!

May the holy-light from some random person with no special knowledge always shine on us all!

For performances, the big advantage of electronic shutter is that it's silent. On my R3, I have the stills/video toggle switch assigned to switch in/out of silent mode. With the stacked sensor, shooting silently doesn't cost me 2-stops of bit depth in my RAW files.

Didn't you mention you noticed in silent mode, the R3 doesn't close the shutter on power off?

Correct. And flash doesn’t work. So now I remember to leave silent mode.

I don't have an R6II, but the R8 has the same sensor and has no problem shooting at ISO 5000. But maybe that's just a miracle that can only happen in some place like St. Peter's Basilica in the Vatican...

Pretty much all Canon FF cameras beyond the R RP have decent performance below ISO 10000.

I feel that there is not much reason to visit this site any longer. Canon has shut down the rumor mills.

Fwiw some of us never used this site for rumours, it's just a little community where people can shoot the breeze and share knowledge and photos.

Very good point. I also like the site because on the day of the announcements they summarize on-line content for what is being announced.

As a scientist I am always skeptical. The only information I believe at this stage is that Canon has registered five cameras in 2024; three are likely R-series cameras and 2 are likely cinema cameras. In terms of announcements, could be May or June; It is anyone's guess.

Having said that, there is a practical implication for using electronic shutter, since the stacked sensor of the R3 enables full 14-bit capture whereas other models drop the bit depth to 12 for electronic shutter.

I assume the bit depth is a bandwidth constraint… 14 bit @30fps for 24mp vs 12 bit @20fps for 45mp both need ~10gb/s bandwidth.

I am not convinced that having a stacked sensor improves the bit depth but the processor bus speed seems more likely to me.
I assume that the new R1/R5ii will both have the next iteration in the digic x family with a higher bus speed

I use EFCS on my 24 MP R8, because that provides 14-bit RAW files while electronic shutter drops it to 12-bits. Note that unlike the R5, the R8 can be set to shoot ES at low-continuous speed of 5 fps…and still delivers only 12-bit RAWs.

How does that align with your assumption?

My assumption is that the 12-bit was picked to get a useable amount of rolling shutter, each bit you drop gets you a faster readout and the max fps is capped by the bandwidth bottleneck.

A stacked sensor, like the R3, would allow full bit-depth images with acceptable rolling shutter, while a newer digic would allow more bandwidth.
I hope this means we can get at least 20fps in e-shutter with full bit depth on the R5II, focus stacking is much less frustrating with fast fps

Even the EOS R has good ISO performance until ISO 8.000. But ISO 12.800 really hits the IQ really hard.

It looks like the Canon Rumors post from the other day got deleted?

Yes, I think it's because of this:

https://twitter.com/x/status/1787188513227575676

it wasn't about the R1/R5II at all.

But it's interesting how a small post from CanonUSA on Xwitter with almost 0 information produced a huge speculative thread here.

It seems English canon rumors have not talked about it.
R1 will support CFexpress type b 4.0. The camera has 3000MB/s writing speed.
This news is from Taiwan memory card company which is ready to sell CFexpress type b 4.0. So R1 bandwidth is large enough ro over 120fps.
I hope R5ii will support this also.

it's been probably said before but a R7C?

That was a rumour about a year ago and then a rumour that it was canceled.

Rumors about rumors of a rumor.
Where are the news?

Todays news is that the rumor about the news is no more.
