Canon RP has a
26.0MP Full frame (35.9 x 24 mm ) sized CMOS sensor and features Digic 8 processor. On the other hand, Sigma fp L has a
61.0MP Full frame (36 x 24 mm ) sized BSI-CMOS sensor .
Sigma fp L's sensor provides 35MP more than Canon RP's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the EOS RP and fp L sensor size comparison.
Sensor Size and Resolution Comparison image of Canon RP and Sigma fp L Cameras
Canon RP and Sigma fp L have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon RP
or the
Sigma fp L ,
including hyperfocal distance.
