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, Sony A58 has a
20.0MP APS-C (23.2 x 15.4 m ) sized CMOS sensor .
Canon RP's sensor provides 6MP more than Sony A58'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 A58 sensor size comparison.
As seen above, Canon RP has a 2.5x Larger sensor area than Sony A58. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
