Canon R50 has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic X processor. On the other hand, Sigma DP1 Merrill has a
15.0MP APS-C (24 x 16 mm ) sized CMOS (Foveon X3) sensor and features Dual TRUE II engine processor.
Canon R50's sensor provides 9MP more than Sigma DP1 Merrill'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 R50 and DP1 Merrill sensor size comparison.
Sensor Size and Resolution Comparison image of Canon R50 and Sigma DP1 Merrill Cameras
As seen above, Sigma DP1 Merrill has a 1.2x Larger sensor area than Canon R50. 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.
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 R50
or the
Sigma DP1 Merrill ,
including hyperfocal distance.
