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, Fujifilm IS Pro has a
6.0MP APS-C (23 x 15.5 mm ) sized CCD sensor .
Canon R50's sensor provides 18MP more than Fujifilm IS Pro'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 IS Pro sensor size comparison.
Sensor Size and Resolution Comparison image of Canon R50 and Fujifilm IS Pro Cameras
Canon R50 and Fujifilm IS Pro 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 R50
or the
Fujifilm IS Pro ,
including hyperfocal distance.
