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.
