Choose a camera according to the sensor

Which one has the best dynamic range and the best ISO sensitivity?

These values are provided by the Photons Stop Photo site for a set of cameras from which we have chosen those included in the comparisons on the site, plus some full-frame cameras added for comparison. Camera are ranked according to the dynamic range, from best to lowest.

Recall that the dynamic range is the index of the ability to clearly reproduce both the lightest and darkest areas in an image, and the ISO sensitivity the ability to see clearly in low light. Dymamic range is more useful for landscape while ISO score est relevant to sport and action.

When it comes to ISO sensitivity, full frame sensors are the best. However Fujifilms equipped with X-Trans sensors are rated very well for both dynamic range and ISO. This is not the case with the X-T200 which has a classic quad Bayer sensor.
The RF-mounted Canon RP wins over APS-C cameras in ISO sensitivity, but it ranks behind all Micro 4/3s on dynamic range criteria!

Dxomark gives a better ISO score to RP than to R. Here is a list of some cameras, sorted by ISO score.

When a full frame camera is used in APS-C mode, with a full frame or APS-C lens, the dynamic range remains about the same, but the ISO sensitivity is halved.
Note that the dynamic range difference between sensors tends to decrease when increasing ISO. The dynamic range of RP drops significantly less than others from ISO 400 and it ranks much better then.
The ISO score is actually the more important factor to consider of the two.
