Dynamic range on the Canon EOS 80D the student is progressing well but still needs improvement.

Since I am at minimum services, I had not realized, but a comment from Guillermo has drawn my attention to the analysis of dynamic range that Dpreview has performed on the new Canon EOS 80D and the results, as you will see in the screenshot that I’m adding below, despite not being amazing, at least they are encouraging.

The method is always the same, the ISO invariance, and if you click the link you will see that by default the EOS 80D and 70D were selected, lifting the shadows +5 EV and + 6EV. I preferred to change it up and put the 80D against the 70D, with the Nikon D7200, and I also wanted to put the Sony Alpha 6300 but I couldn’t find it, so I put the tiny Sony RX100 IV, which is already unfair because it has a tiny 1" sensor, substantially smaller than the APS-C size of all others. In all cases I have raised the shadows +5 EV, which is fine.

Doesn’t take a genius to figure out many things.

  • There is clearly an improvement between 80D and 70D, despite its modest increase in resolution of 20 to 24 megapixels.
  • There is also a clear difference between the Canon and Nikon, which is much cleaner.
  • Note that the 80D (and also the 70D) has the "dual pixel AF", which means that each pixel is divided into two, for whatever that’s worth and whatever the impact that has on noise and dynamic range, which I do not know.
    Overall we can say that "the student is progressing well, but a little slowly and needs improvement." Sony, for a small fee, offers to give remedial classes, and if I were Mr. Canon I would take them, that is as long as no one knows it and it does not transcend so that the superEGO of Mr. Canon remains intact.

The small Sony is here only as an extra and it serves to remind us that the laws of physics are very stubborn, and that the size of the sensor (actually the photodetector pixel) clearly influences the noise and dynamic range.

We are talking about the APS-C world, and I do not know until which point that could be extrapolated to the FF world, but of course the outlook is encouraging, and I say this selfishly thinking of the future EOS 5D Mark IV or whatever they call it.

With the sole purpose of being annoying and not to reassure you, I have not resisted the temptation to replace the tiny Sony RX100 IV with the huge Canon 5DS-R.

You will see that the 80D retrieves a better than 5DS-R by a hair, keeping in mind the latter is FF. Does that mean that the sensor of the 80D is better than the 5DS-R or this is the price to pay for the megapixel hypertrophy of the latter?

I am not able to give an informed answer, but if I can give a clue that comes from the hackneyed rule of three.

If the sensor of the 80D was FF, it would be 61 megapixels.

So, what do you think?
