PhotonsToPhotos Results for the EOS R1

[Quarkcharmed]

So, they call this "Tonal Dynamics" but it seems to follow Imatests test method for dynamic range. The "Wysoka" and P2Ps definition (minus CoC) are both 20 dB. I am not saying exact results should mirror each other as anything in how this is set up/analyzed could vary a bit.

CoC is crucial here - it's basically the normalisation in the P2P method. PDR is a normalised metric - it measures noise in the images as if they were printed the same target size and viewed from the same distance.

So the PDR and measurements from Optyczne are not comparable.

However you can check EDR from P2P: https://www.photonstophotos.net/Charts/RN_e.htm
select a camera and then click on the button with the camera name in the top right, you'll see this. That'll be, roughly speaking, per-pixel DR.

I did and I can.
I never said that the R5 II was better at everything.

You are wrong. I've used both the R5II, A1 and also the R5, R3. The R1 should have more dynamic range compared to the R5II. The A1 II and A1 should also have the same dynamic range.

You can throw out dynamic range charts all you want but the R5II's dynamic range isn't across the board dynamic range for everything except 8K RAW. If you want to make the R5II into a spec camera then go ahead but lot's of people have used the R3 and R5II and most say the R3 has better dynamic range for phot and video compared to the R5II.

Rent and used both the A1 and R5II and come back and let everyone know what you think. I still have the R5 and sent back the R5II for the A1 so we will so how this works out. I'm still getting used to Sony color and how it treats dynamic range because whatever Sony is doing under the hood is different.

The reason I went with the A1 is because I couldn't get around Canon's overheating issues.

I disagree.
I predict that we will see a wave of Canon bashing.
People can't stop complaining about the R5 II.

The R5ii is pretty remarkable and shows well compared to the R3 and R1 on dynamic range vs iso. Look of the electronic shutter comparison on photonstohotos.

Interesting dynamic range vs. ISO of Canon R1 to Canon R5ii to Canon R5

Everyone that was criticizing the Sony A9iii for its lack of dynamic range will now say: ohhh you see the Canon R1 is not that bad , it competes with A9iii , so it’s all good . That’s called hypocrisy
But anyways , I love my R1 but it seems every camera company moving forward , makes a step backwards when it comes to image quality and It’s all about speed now .

The criticism was for the loss of dynamic range from the A9II to the A9III but with a substantial increase in price for the camera. For still photographers paying $$$$ for IQ. the slight increase in global shutter readout is a wash for the price one is paying hardware wise. Processing is still limited by the write to disk speed. The speed didn't create a substantial more hit rates or income in stills. Reason the global shutter hasn't garnered much traction in still photography since it was invented by Kodak back in the 1970s. Ok for motion picture and video, but has relatively little use in still photography and not worth the $$$$. Once stacked sensors reach 2 - 3ms the advantage of the GS for still photography is a wash hence the criticism for a $6800 + tax camera that doesn't capture any more stills faster than the R1 or R3
