This is just a Sunday reminder of the Canon EOS R5 specifications
- Thread starter Canon Rumors Guy
- Start date
I haven't kept up with the findings on their color science I did not know it was that good; but I definitely like their BRAW codec. I did not take color science that seriously until I started shooting with the GH5. Great camera, packed with features, but so difficult to color grade.
Another issue I have heard about Blackmagic cameras is they aren't that great in low light. Personally I think if you learn your camera, the log curve you are shooting with, and the color space you are shooting in, and expose properly for those factors you can properly handle noise in post and that applies to any camera.
A final issue is that Blackmagic is truly a video body, any body Canon releases that is not a part of the cinema line will be excellent at photography as well, so IMO the only thing Canon really needs to beat is Canon.

My Spokane so you think the DR will be the same as the almost 5 year old 5Dm4? I’m not trying to get the DR issue going just wanted to know if there might be some improvement for wildlife dawn and dusk. If the MP go up with no loss of DR I suppose in a way that is an improvement.

What level of improvement are you expecting? Modern sensors are basically as good as it gets for now.
Using the two different exposures from the DPRAW for improved DR can cause artifacts in partially blown out areas, so I doubt we'll ever* see an official Canon version. As far as I understand, there are improvements in high ISO DR to be had using multiple amplifiers, but we haven't seen this in the 1DX III. So I doubt we'll see anything like that in the R5.
*on second thought, they definitely can work around this so in time, or one resolutions become great enough anyway, this may change.
No banding even in extreme boosts (~5 stops and beyond) and finer detail (Higher resolution, fine low pass filter) are the improvements I'd expect over the R / 5D IV. DR, especially at base ISo, not so much.

I still don't know why there are no SSD interfaces. Maybe the R5 will have one.

“The official Canon version“ is DGO. Available commercially right now:

I don't expect it to. Canon has been know to make cameras that are built like tanks. Relying an a USB cable to an external SSD for extended storage does not sound reliable, or weather proof. I use an external SSD on my Blackmagic cameras, but they are also not know for their ruggedness like Canon is.
Also, internally CFExpress is essensially a NVME SSD in a portable form, running on a PCIe 3.0 x2 bus. So much faster and scalable interface than CFast that was essensially an SATA 6Gbps SSD interface at base.

Maybe but remember that the Pocket 4K did not originally ship with 2.6K/120, it could only do 1080/120.
Blackmagic added it through firmware.

Very interesting, thank you for bringing that to my attention.
I am not sure if that relates directly to creating a HDR image from the two sub pixels in a Dual Pixel CMOS though. From reading into it, I get the impression that it is a system like what Arri has been using?
"The DGO Sensor is a newly developed imaging system that generates high dynamic range and maintains low noise levels by reading out each photodiode with two different gains. It combines the two with saturation prioritizing gain for bright areas, and a lower noise prioritizing gain for darker areas."
Source: https://www.usa.canon.com/internet/...a-eos/eos-c300-mark-iii-digital-cinema-camera
So each photodiode is amplified with two different gains according to this marketing info. But a Dual Pixel Cmos has two diodes for each pixel. If they specifically use different amplification for both the left and right diode of each pixel, why wouldn't they say so? They could have written that the two halves are amplified differently and combines in a special manner. From that text, it appears as if this is not about the two halves.
However in this lab test by Cinema5d it is shown that the rolling shutter is cut in less than half when DGO is turned off at the higher frame rates. To me that suggests that the two sub pixels do play a role in DGO, and when the feature is disabled they are combined as usual.
I'm not sure if they have worked around the parallax issues somehow and are using a modified version of DP CMOS here, or if they have taken a page out of ARRIs handbook.

Depends on whether you're talking raw or JPEG/HEIF.
Several other models besides the 1-series have unlimited buffer shooting JPEG.

I agree that any improvements in base ISO DR will be so minor that you'll need to work to see the difference, but the 1DXIII did see some improvement in DR at base ISO and is now ahead of the a9II by the slimmest of margins. There was a CR1 rumour here a few months ago (for what that's worth) that suggested that the new sensor design would be putting a lot of emphasis on dynamic range, and considering that we saw an improvement in the 1DXIII, I wouldn't rule out an improvement to base ISO DR for the R5. Whether or not that matters to most people's photography is an entirely different discussion which has been beaten to death here, but I don't think an improvement is impossible, or even unlikely.

According to the Swedish Canon Website (https://www.canon.se/cameras/eos-r5/) it has an advanced tracking-AF that can track the body, face or eye of dogs, cats and birds.
I assume it can do the same for humans
Now wouldn't that be just like Canon to leave out humans...
Thank you very much for that useful and quite logical description of how things are probably done.
So perhaps part of the problem is that in this time of pandemic with 'social distancing' and limitations on the number of people on a given space, there really is only one person doing all the work...
When we get our cameras, that "Inspected by 42" stick may really mean the same person for all of them.
