These results, processed using the site's standard Canon Digital Photo Professional RAW processing parameters (including a very low "1" sharpening strength setting) facilitate comparisons with other cameras. I suggest using the f/4 or f/5.6 aperture test result to ensure that a very sharp lens setting was in front of the camera.
Comparing the 90D to the 80D is a good starting point. Here we see the higher resolution 32 MP imaging sensor showing its advantage over the previous-standard 24 MP sensor.
Another interesting comparison is between the 90D's f/5.6 and f/8.0 results. These show the effects of diffraction starting to show at f/8. The effect is especially noticeable at f/11 where dimishing returns are being seen from this sensor's extreme resolution. Note that the higher resolution sensors results will be at least as good as (and very potentially better than) lower resolution images captured at the same aperture setting when compared at the same overall output size.
